corona-9-3dsmax-daily-2022-07-12.exe

General

• Added Corona Pattern modifier
• Added support for Chaos Cosmos Decals assets
• Added option to preserve slicer materials when using material override
• Added possibility to preserve material opacity and bump when using override material
• ACES OT tonemapping operator is now used by default

• Improved metals detection and materials conversion in Corona Converter
• Improved conversion of refractive materials in Corona Converter (materials with black refraction color are no longer treated as refractive materials)
• Removed support for 3ds Max 2014 and 2015
• Removed warning about using V-ray bitmap in IR (it works correctly)

Experimental

• Added support for out of core textures - currently off by default
• can be enabled in devel settings by increasing the HDD cache size to non-zero value

Fixes

• Fixed Corona Bitmap mapping in High Quality Max viewport

• Fixed Y-axis being reversed when sampling colors - i.e. picking the value from the top of viewport picked it from the bottom

Chaos Scatter

• Chaos Scatter requires license only when its UI is on, not during the whole 3ds Max session. Rendering scattered instances is unlimited.
• Fixed endless IR restarts in V-Ray in certain situations (e.g. when using IFL file as density map).
• Cosmos models imported as part of Scatter presets are disabled for rendering. If needed, it can be enabled again in 3ds Max, in object properties of each of the models.
