Corona Renderer for Cinema 4D Beta 1 released!

We are pleased to announce that Corona Renderer for Cinema 4D Beta 1 is released!

The main purpose of Beta 1 was the implementation of Interactive Rendering. To be able to do that, we have rewritten a big part of the plugin (nearly every part of the plugin was touched), so it took quite a long time to stabilize all of Corona Renderer with so many changes.

The good news is that this big rewrite allowed us to implement Interactive Rendering that includes support of standard Cinema 4D and 3rd-party shaders, and that it also allowed us to quickly implement the Shadow Catcher and finally native Material stacking, so I am sure you’ll agree it was worth the wait!

During the development of Beta 1, we updated twice to the new core, first to 1.6 and then to 1.7.2, which is the most up-to-date core. We also released 21 daily builds, so we’d like to thank all of you for testing them and helping us to finally release the stable version!

Compared to the previous Alpha version, there have been a huge number of bug fixes (some longer-existing bugs still persist, but that’s why we’ve always had Beta 2 planned), and there have been a lot of new features and new functionality implemented.

I have decided to take this opportunity to inform you about the recent news, changes and improvements within Render Legion which we plan for 2018. Some of our plans still have to be kept secret, but I am able to reveal some of them.


In 2017, we hired 8 new members onto our team, taking the total to 25. We plan to grow our team significantly in 2018: at the moment we have 29 new positions planned. We are hiring not only developers – who will boost the development of the 3ds Max and Cinema 4D plugins and the Corona core, and will also drive the development of our future products – but we are also looking for Support Representatives, Project Managers, and Researchers.

If you are interested in working with us, please be sure to check our Jobs section regularly, as we update it quite often.  We are dedicated to improving what we have, and to deliver better products and better services for you, our beloved Coronauts.

Now, together with our bigger brother Chaos Group in the back, we are encouraged and able to reach greater heights and achieve more goals, and we are committed to walk the talk!


3ds Max plugin

Future releases of Corona Renderer (3ds Max and Cinema 4D) will focus more on compatibility with V-Ray. We have already started this process with the 3ds Max plugin, and the next release (Corona Renderer 2 for 3ds Max) will expose some of the cross-compatibility, while the subsequent version should bring the majority of cross-compatibility features.

You can check our roadmap here:

Cinema 4D plugin

Development of the 3ds Max plugin is now almost frictionless, so we have decided to commit ourselves even more to delivering a strong and stable Cinema 4D plugin. It is safe to say that we will put all our spotlights on to C4D from now on – we have already hired a fourth developer for the Cinema 4D team, and the C4D team will receive a dedicated Product Manager and Support Specialist later this year.

Check our roadmap here: 

SketchUp plugin

Let’s admit it, the last year was not that successful for our SketchUp plugin: we had two developers who came, did a small amount of work, and then left. For the past few months, there has been virtually no progress on the plugin. We also hit some roadblocks in development, which did not help.

By the end of the year, we were faced with a tough decision on what to do with the plugin. Should we scrap it? Or maybe reboot the development from scratch? All the while, we had to evaluate if any of that made sense, especially now that our colleagues from ChaosGroup have released their strong V-Ray 3.6 plugin for SketchUp (please check it on  CG’s website , it’s worth it!)

Our conclusion was a tough one, but after a lot of soul-searching we have chosen to end  development of the SketchUp plugin for good. We have decided that it makes most sense for us to focus all our efforts and manpower on the Cinema 4D plugin, which is really promising and very close to the finish line.

I know that this kind of news is always hard to read – and even harder to write – but to be honest if we compare what V-Ray offers for SketchUp and what we have now, we have to be realistic and admit that they did a far better job than us.

So, now we would rather focus our time and effort on the Cinema 4D plugin where we think we can offer more.  I am sorry to those who we have disappointed with this move, but we sincerely think it is the best possible one.

Next “undisclosed” plugin!

We have decided to do a couple of “test integrations” for Corona Renderer. The goal is to create something in a quick and dirty fashion, to evaluate the possibility of bringing Corona Renderer to other applications.

At the moment we are working on the first test integration which we will evaluate soon. All I can say at the moment is that the applications which we are testing are mostly from the AEC industry segment.

Thank you!

As always I want to thank you, our users, for your enthusiasm and passion for Corona Renderer, and for your tireless testing – and yes even for your feature requests! You are all part of the Corona team along with us.




Here is the overview of the changes since Alpha 6!

New Additions

  • Cinema 4D R19 fully supported
  • Interactive Rendering now fully supported
  • Native stacking of materials supported
  • Shadowcatcher material added
  • New improved sampler, for less noise in the same number of passes / same time
  • Dispersion and Subsurface Scattering added to the Corona Material for more realism when required
  • Render Selected Object functionality added
  • Resume Render functionality added to VFB and native Picture Viewer
  • Corona Image Editor added to the installer, for macOS and Windows


  • LightMix “bake to scene” functionality greatly improved
  • Team Render now close to fully functional (remaining limitations to be removed in Beta 2)
  • A LOT of bug fixes!

And now all the new features and improvements in detail!



Interactive rendering

Interactive rendering is now fully supported in the Corona VFB. It detects all changes in the scene such as camera movement and parameters, editing of materials and geometry, environment changes, changes to objects and materials from Expresso, and more.

Native stacking of materials

This long-awaited feature is finally implemented in Beta 1! Cinema 4D lets you assign as many materials on an object as you like, and we now fully support this feature in Corona Renderer.

Materials can be stacked (layered) on top of the previous, and when a higher material is partially transparent or doesn’t cover the whole lower material, then the lower material is visible as expected. This means that stickers and labels can be created very easily, for example.

This new feature also brings the possibility to assign materials to front, back or both sides of a polygon, and both features work seamlessly together and with polygon selections, layered materials, ray switcher, and so on.

Shadow Catcher material

The new Corona Shadow Catcher material allows you to seamlessly and realistically combine your 3D scene with an HDRI map or a backplate image. This allows your objects to interact with the existing image by occluding lights and casting shadows as if they were there when the image was captured!

Lining up your object or camera’s point of view is made simple thanks to the Interactive Renderer, too.

Matching perspective to the backplate for the Shadow Catcher is easy using Interactive Rendering (free HDRI from HDRI Hub, free car model from Turbosquid)


New improved sampler

Thanks to the update to the latest core, we now use the new DMC sampler as the default sampler. This new sampler is capable of speeding up your renders by up to 2 times i.e. it produces much less noise for the same number of passes as the previous default sampler, so you can render less passes (which means less time) for the same amount of noise.

The comparisons below were rendered for the same number of passes in both the old and new samplers, with one scene without materials to emphasize the noise alone, and the other a real-world use in a full scene:


Dispersion and Subsurface scattering

More great features which come with the the new core are Dispersion and Subsurface Scattering, which are fully integrated into the standard Corona Material. These allow you to produce more realistic renders than before in scenes where these effects are required.

Render selected object

This is another feature which users have been asking us to implement for a while! It allows you to render only the selected object from the viewport (and unselected objects will not be shown in the rendered image), or users can specify what to render/not render in an include/exclude list. The feature works both in a final render, and in Interactive Rendering.

Improved LightMix “bake to scene” functionality

The LightMix “>Scene” button can “bake” adjusted light parameters from post-processing into the scene lights, and now also supports baking of instanced lights. Baking is useful when you want to increase the intensity of a light to a much higher level, but doing this purely in LightMix would also increase the noise (like in the sample image shown below).

In such cases, the new values set using LightMix can be transferred to the scene and the image re-rendered with the brighter lighting, giving less noise as the renderer can work with the higher intensity at render time.

Team Render

Team Render is much more stable, and should be close to fully-functional. Known limitations are – it is best used from the native Picture Viewer, and it cannot use Noise Level, Adaptivity or Denoising yet. These limitations will be removed in Beta 2.


Resume render

If you were forced to stop rendering before an image was complete, you can now save this “half-rendered” image and resume the rendering later. This feature works for the VFB and the Picture Viewer.

You can also use this feature to add additional passes on top of an already rendered image, if you later decide those would have been useful. You can choose to resume the last render if it is still loaded in the VFB, or simply save the render to Corona EXR (.CXR) format to be able to use this feature at a later time or date.

Support for C4D R19

Both Windows and macOS installers now include a version of Corona Renderer for Cinema 4D R19, and it is automatically detected during installation so you can easily start using Corona Renderer without any problem.


Corona Image Editor

For some time, the Corona Image Editor (or CIE as we like to call it) has been part of  the 3ds Max installers. It offers rich and fast post-processing options for Corona EXRs saved from the VFB:  LightMix, full-featured denoising, tone mapping, LUTs, bloom and glare, curves, blur / sharpen, vignette, etc.

Because Corona Renderer for Cinema 4D is also distributed for macOS, we ported the CIE to this platform too and added it to both Windows and macOS installers. Now the CIE can be used on both platforms without any limitation, as shown below using the free Paris Apartment scene from Slashcube:

And of course there have been a great many bug fixes too. It all adds up to Beta 1 being a quantum leap ahead of the previous Alpha release!



Now we move on to creating Beta 2, which will include the addition of Hair and Skin materials, the Node-based material editor, a Corona scene converter, further improvements to Interactive Rendering, a new implementation of Motion Blur, and more – follow progress on the Corona Renderer for Cinema 4D roadmap!

Thank you to our community for your testing and feedback!

Nik, Ales, Cestmir, and the Corona Team!

    1. Thank you, glad to hear you are enjoying it so much 🙂 Makes the hardwork worthwhile, because that’s what it’s all about! Thanks, Tom

  1. Great renderer, waiting to pay for it. Plase integrate the slicer object what vray already did. As an architect, it is very time saving for me.

    1. Thank you, glad you are enjoying Corona Renderer! On the slicer, that would have to begin with a change to the core, which begins with the 3ds Max version, before getting ported to the Cinema 4D version. It is on the roadmap there ( for Corona Renderer 3 (or beyond), so keep an eye on the roadmap for progress on that! Thanks! Tom

    1. Thank you amauryska! It’s always great to hear how much people love Corona, and so glad you like it! Tom

  2. Phantastic! You guys are Artists.
    Sice using Corona, rendering became the best part of my work as a product designer & interior architect.

    Five stars!

  3. As a C4D user I’m stoked about the fact you put so much effort in the development of porting the plugin to C4D, so thanks for that. In your presentation last year at the EUE, you talked about the material library and that it also would be available for C4D users. This doesn’t show in the roadmap, so I was wondering if that is still your plan?

    Thanks anyway!

    1. Hi Emel! We definitely still want to incorporate the Material Library into C4D – it’s not on the roadmap yet though as we are not yet sure it will be possible, and if it is, how it will be done. So while it is definitely still on our list, it doesn’t show up on the plan as we don’t quite know yet where it would fit in! We’ll update the roadmap as soon as we have some concrete information to put in there, though! Glad to hear you are so stoked about Corona, and we’ll continue to put in all our efforts into its development 🙂 Cheers! Tom

  4. Amazing work.
    Corona for C4D is the best render engine I’ve used. I’m obsessed with it. The interactive rendering is perfect. This will go far. Thanks

    1. Thanks Dave! So glad you are enjoying it – and it will only get better still! 🙂 Cheers! Tom

  5. like your renderer.
    miss the very useful c4d multipass where I can create user defined object channels.
    your multipass feature doesn’t offer this?
    for me a deal breaker.
    will you bring this in the final?

  6. Everything is going excelent, but i would love if a i could zoom out of the working space in the interactive render window. The size of the windows gets stop by the actual out size of the rendering taking to much space in the screen. Keep working

  7. I got the issue with rendering the cloud and When I see OpenVDB render in Corona I decided to jump. But after I realize it’s not support for Corona for C4D, I was pain and disapoint. Why didn’t you add vdb feature to C4D ?

    1. Hi David, we primarily develop Corona Renderer for 3ds Max, so this version will always receive the major updates first. Then they are ported to C4D, and it has to take some time. You will see OpenVDB support in Corona Renderer for C4D as soon as possible, but we can never guarantee that the feature updates will be released on the same day for all platforms (since it’s impossible).

  8. Dear developers! I ask you to release a full commercial version of the corona renderer for Cinema 4D, add a math node system for fine-tuning the materials !!! Tell me how many more do I have to wait for the full version of this render? Not everyone will prefer to work in the bug dinosaur 3D Max! Cinema 4d is the future.

  9. Dear developers of this magnificent render! I beg you to reconsider your views regarding Cinema 4D. So please, please make a full commercial version of the corona render for Cinema 4d!!!

    1. Hi! I am not sure which views we should reconsider 🙂 Our view is that we will develop the finest, most closely integrated, easiest to use render engine extension for Cinema 4D, featuring a material node editor, that has the same power and functionality as the core (3ds Max) version, and that keeps pace with changes in that core version in a timely manner. We are already making the full commercial version, and once it Corona for Cinema 4D is feature-complete and working fully, it will no longer be free and will require a paid license (it’s only free just now while it is in development; it’s not a cut-down free version or anything like that, we just like to give it to everyone free as our way of saying thanks for testing, reporting bugs, making feature requests etc.). I am pretty sure none of our views there are ones you’re asking us to change 🙂

      As for how long it takes to get to a final, paid version, well, that’s just because we are making sure it works well and has all the bugs removed and all the features we want included. It does take time to get there, unfortunately – but we are working as fast as we can on that!


  10. Hi guys! After 3 weeks of successful rendering I got licence problem with Beta1 at C4D R18 (Win7 64 bit Ultimate). At start of C4D i got message:
    “No active licence found on this computer”
    My internet connection is working.
    How to manage the problem?

    1. Our helpdesk article for this is here –

      As noted, if things are not working, there is a contact us section on that page which will let the support team pick up the issue and work with you to resolve it. Sorry you are having troubles, check out that page, and use the contact from there if you are still experiencing issues! Thanks!

  11. Thank you for all the hard work you’re doing to make this possible. I can see high potential for corona to catch up with the render engines on the market in the near future. I love to see how this plugin will evolve.
    Thank you all!!!.
