User-Facing Improvements

  • Added option to save image that can be later used with AI Enhancer.
  • Better max values for night sky multipliers.
  • Added support for export of IES lights to Vantage.
  • Added high-res moon version.
  • Light lister in Corona lights now opens lister’s Lights tab.
  • Added MAXScript functions to change lightmix parameters (enable/disable, tint, intensity).
  • Fit to bitmap account for cropping.
  • Added seed control to offset and rotation in the Corona pattern.
  • Rewritten “Save options” dialog for image saving to Qt, re-added it into CIE, replaced the WxWidgets implementation in Standalone.
  • AI Enhancer - Adding preview attribute to uploaded EXR image for faster upload and avoiding dummy placeholder for >65MB images. Limit of 300MB for image size stays.
  • Image filter is automatically set to tent if AI denoising is used in production rendering.

Bugfixes

  • Fixed B&G not displaying in non-tonemapped elements after switching from element with B&G disabled.
  • Fixed disappearing stars for small camera FOV.
  • Fixed issue, where Chaos Scatter export/live link to Vantage was not working correctly.
  • Fixed infinite IR restarts with the moon.
  • Fixed wrong region being rendered during IR in zoomed & flipped image.
  • Fixed a bug where slicer didn’t work when decal was intersecting it. Also fixes inverse slicer when using volumetric/SSS materials.
  • Fixed artifacts that would sometimes appear when using bloom&glare with night sky.
  • Fixed crash when using Corona Render Elements Manager script.
  • Fixes issue where removing legacy atmospheric shaders could lead to crash if the shaders were removed by Max Scene converter.
  • Ensure Corona does not crash when encountering corrupted meshes from 3ds Max.
  • Fixed issue where IR was restarted even though time/frame did not actually change.
  • Fixed issue where Fabric material has a wrong material ID.
  • Fixed issue where Corona was crashing when LUT was used and “Convert local file paths to relative” was used.
  • Fixed behavior of “Prevent black appearance” for light sources/light materials - previously it could generate stronger emission in direct visibility or lower emission when occlude other lights was disabled.
  • Fixed issue where Corona could crash when exporting scene to Vantage if the scene contained some third party textures.
  • Fixed issue where metal V-Ray material would be dimmed after conversion.
  • Fixed issue where IR might spuriously restart when using geometry motion blur.
  • Fixed issue where CXR might be wrongly saved after IR has stopped.
