Corona Renderer 1.6 for Autodesk 3ds Max Released

The latest update to the Corona Renderer once again brings many new features to this CPU-based un(biased) photorealistic renderer. The focus is on speed in rendering & workflow, with overhauled Distributed Rendering, improvements to IR, the Corona Image Editor for working with your images outside of any 3D application, bake LightMix settings into the scene, 3ds Max 2018 support, and more!

Below you’ll see user created art and the highlights of the new features available with the release of Corona Renderer 1.6. I am specifically happy to learn Corona for SketchUp is back on track, with a new developer joining the team for it. Welcome, Standa 🙂

I’m looking forward seeing all the new and good stuff directly by the creators during Corona Academy this weekend… Also getting them on record for the Spectroom Podcast which is going to be released very soon!

Now… on with the features :

3d rendering done in Corona Renderer –

Distributed Rendering Overhaul

Distributed Rendering overhaul – Makes it easier than ever to leverage the power of all available machines. Improvements include 3ds Max being pre-started on all slave machines to reduce wait times; assets that are missing on the slave machines are transferred automatically only to those machines that need them; Corona DR now works with adaptivity, and rendering to a noise level limit; and more detailed and accurate information is displayed on master and slave machines, e.g. showing memory usage.

Interactive LightMix

The unique Interactive LightMix feature now allows changes made in the VFB to be baked into the scene, making LightMix an ideal way to set up lighting rather than edit individual lights. The automatic LightMix setup has been improved with the option to setup via instanced, grouped or individual lights, with the memory requirements shown for each different setup.

Corona Image Editor

The new standalone Corona Image Editor (CIE) allows all denoising, LightMix and post-processing functionality to be used on Corona EXR files, giving access to all the Corona VFB features outside of any 3D software and without the need to re-render. Standard EXR files can also be loaded, and Corona post-processing effects such as tone mapping, bloom and glare, etc. can be applied. Post-processing and LightMix configurations can easily be exchanged between the CIE and the Corona VFB.

And More…

Post-processing options have been extended, with custom tone curves, sharpen/blur capability, and improved vignetting.

New improved shading means that faceted terminator shadows on low-poly objects and materials with bump maps are no longer an issue.

Other improvements include subsampling in Interactive Rendering, allowing much faster updates; new options for Corona Scatter to place objects along splines or in regular patterns; Triplanar mapping; non-360 stereo rendering; support for 3ds Max native 2D Pan Zoom and Lens Distortion; improved Corona RoundEdges map rendering; fuzzy render regions; and more.

The update also brings with it an extensive list of other improvements, features and bug fixes, and is compatible with 3ds Max versions 2012 to 2018.

Full information on the changes is available in the official Corona Renderer 1.6 for 3ds Max Released! blog post

Corona Renderer 1.6 for Autodesk 3ds Max is available for purchase on the developer’s website at and there is also a 45-day unlimited demo version for download.

Render Legion s.r.o. are developers of the Corona Render engine. Commercially available since 2014, Corona Renderer is fully integrated into 3ds Max, with integrated Cinema 4D and SketchUp (Ay Caramba) versions in development.
