Corona Renderer 7 for 3ds Max - Daily Builds Changelog

corona-7-3dsmax-daily-2021-06-03.exe

  • Improved Sky model - Added final version of the improved sky model. Unlike the previous version this one contains additional parameters: altitude and turbidity. - Note: This may change the look of scenes which use the Improved Sky model

  • Displacement - Fixed bug where displacement was removed even if override material was off, added preservation of displacement from layered material

    • Fixed displacement map being clamped to [0,1] range
    • Fixed displacement being wrongly applied in cases where it shouldn’t be
  • PhysicalMtl - Added switch to system settings determining whether IOR or specular mode is used as a default

corona-7-3dsmax-RC1.exe

  • Corona Converter - Simplified the shading networks generated by the conversion
    • VRayMtl is now converted to CoronaPhysicalMtl directly instead of using CoronaLegacyMtl as an intermediate step
    • Made the error log more readable by adding additional indentation and newlines
    • Added better warning when V-Ray is not installed
  • General - Fixed crashes in some cases when bump map is evaluated to NaNs
    • CoronaNormal - improved tooltip for the “Add gamma to input” checkbox

corona-7-3dsmax-RC2.exe

  • Improved sky model - Added atmospheric shader!(http://new fog.jpg) - Current known limitation: This does not function well with multiple suns/skies.
    • Corona no longer needs improved sky model data to properly load. If the data is not found we automatically switch to Hosek&Wilkie model and show an error message.
  • Corona Converter - Fixed errors during conversion with V-Ray 4
    • Fixed errors when converting Mental Ray and V-Ray portals
    • Fixed duplicate CoronaColor nodes being generated in some cases
    • Removed “Fix Bitmaps using “Mono Channel Output” used as opacity maps” button from Corona Converter - this functionality already works without the need for fix
  • General - Fixed “connection failed” issue when using “search on LAN” after “search LAN” in Distributed Rendering

corona-7-3dsmax-RC3.exe

  • Improved sky model - Fixed green haze
  • General - Optimized scene parsing in some rare cases (e.g. displaced light sources)
    • Fixed DrServer in command line mode ignoring output being redirected to a file.
    • Fixed V6 regression of LightMix render element not shown by default when starting render
    • Fixed crash during scene parsing when using Pro Optimizer modifier
    • Fixed some rendering artefacts caused by infinite values in textures (e.g. EXR)

corona-7-3dsmax-RC4.exe

  • Improved sky model - Fixed the improved sky volume effect having incorrect color (usually a magenta tint) when viewed through refractive or transparent surface
    • Remapped Improved sky model turbidity, so its default value is now the same as for the other models (2.5) - Note that this will unfortunately change a look of scenes created in the recent daily builds
  • Corona converter - Improved propagation of reflection parameters from original materials to CoronaPhysicalMtl.
    • Fixed incorrect conversion when PhysicalMtl is set to use specular instead of IOR by default
    • Fixed asserts during conversions of some scenes
  • General - Open Image Denoise (Intel AI denoiser) updated to version 1.4.1 - fixes some crashes when denoising certain resolutions
    • Fixed rare crash caused by rounding errors when evaluating texture map for a given pixel
    • Fixed crash when the Corona improved color picker is launched from maxscript colorPickerDlg function
    • Fixed crash when a Falloff map in Fresnel mode is connected to an IOR slot of any material through another map - Note that Falloff map in Fresnel mode is not supported in the IOR slot by Corona and doing this will trigger a warning and the material will be rendered as if nothing was connected to the IOR slot.

corona-7-3dsmax-RC5.exe

  • Improved sky model - Fixed new sky model being black below horizon in orthographic cameras
  • Corona converter - Fixed more problems when converting with having V-Ray 4 installed
    • When reporting problematic materials to maxscript listener, each material is now printed on a separate line, to improve readability
  • General - Added support for rendering newer Ornatrix objects
    • Fixed artifacts in the bloom & glare effect in some cases with very bright lights
    • Fixed some entries in viewport right click menu being disabled the first time this menu is open in a 3ds Max session
    • Fixed crash during 3ds Max startup when a Corona licensing log file cannot be opened for some reason

corona-7-3dsmax-RC6.exe

  • Improved sky model - Fixed green/magenta tint in the new improved sky model volumetric effect when computed for short distances (under 200 meters)
    • Reintroduced fake horizon blur for Improved sky model. Default horizon blur is now 0, since the blurring should be controlled by the physically correct altitude parameter.
  • Corona converter - Fixed an issue with reflection parameters not being computed correctly when reflection map, IoR map or both were plugged to the original material.
    • Fixed asserts during conversion of some scenes in certain 3ds Max versions
    • Fixed “convert by class” not working for 3ds Max physical material
    • Fixed conversion not preserving the “show background in preview” option
    • Conversion now preserves material ID channel
    • Conversion from VRay2SidedMtl to CoronaPhysicalMtl now produces simpler shading networks
    • Polished the UI
  • General - Bucket rendering disabled for IR, because in some cases it is still too visually distracting. - Buckets are still enabled in production rendering after 5 passes, and in DR/Backburner/command line render from the render start, to get better performance. We’ll experiment with IR buckets more in v8 to get some better solution.
    • Fixed render to texture not working
    • Fixed crash when using Forest Pack version 6
    • Fixed excessive rendering times and RAM usage in some corner cases caused by refraction
    • Fixed some checkbox labels being clipped in the render settings dialog
    • Added tooltip to randomization mode of MultiMap and UvwRandomizer mode, explaining that the “Instance” randomization is based on a node name and will change when the node is renamed
    • Added warning when proxy contains corrupted normals which cause it to render differently depending on whether the “keep in RAM” checkbox is checked.

EDIT:

  • Material Library - Added 13 new metal materials
    • Added 13 new masonry materials
    • Added 9 new wood materials - All new materials are built upon the new physical material
    • Converted existing carpets, ceramic tiles, concrete and flooring materials to the new physical material - Note that this might result in a slightly different visual result, however existing scenes based on the previous versions of material library will be unaffected

corona-7-3dsmax-RC7.exe

  • General - Fixed objects with displacement disappearing in IR if you immediately resize the VFB during parsing
    • Fixed possible crashes occurring when VRayBitmap is plugged as density map in Corona Scatter.
  • Corona converter - Fixed environment mapping type being changed when converting from CoronaBitmap to 3ds Max Bitmap
