Version v0.12.0

• Revamps treatment of MultiMaterials:
  • MultiMaterials are, once again, detached and treated individually within 3ds Max;
  • MultiMaterials are now only treated as "containers/compounds of other materials";
  • At the end of the inner-DCC operations, after baking/rendering, they are reattached;
  • The submaterials are translated individually outside of 3ds Max, maintaining their individual properties;
  • This method provides better visual quality, and in some cases improved performance.
• MultiMaterials and Shell Materials are now classified as Supported Materials for input scenes.
• The padding for material atlas baking has been reduced:
  • The padding is now proportionally dependent on the resolution in use for baking, for example:
    • 256 - 2px;
    • 512 - 4px;
    • 1024 - 8px;
    • 2048 - 16px;
    • 4096 - 32px.
  • In short, 1px of padding is added for each 2px of baking;
  • This change allows for considerable improvement in baking performance.
• Improves VRayDisplacementModifier conversion into Bump maps:
  • Reduced the number of VRayBumpMtl materials created to one material per modifier/material pair.
  • Modifiers that can't be baked to geometry (e.g. 2D displacement and SubDivision Displacement) are now always converted to Bump.
• Adjusted material conversion for Hair & Fur geometry.
• Adjusted error checking when adding modifiers to geometry nodes.
• Adjusted Falloff conversion:
  • The replacement of Falloff by black color/texture is now only performed on Falloff texmaps connected to the reflection slots of VRayMtls;
  • All other Falloffs are converted to an 80/20 mix between Front & Side texmap/color.
• Revamped vertex color cleaning operations:
  • A more efficient vertex color cleaning method has been implemented, improving performance;
  • Additionally, vertex colors are now only cleaned for geometry nodes that have vertex colors applied, improving performance even further.
• Revamped two sided geometry operation, for volumetric materials:
  • The Shell Modifier is no longer used;
  • This operation is now only performed if an object is not watertight, improving performance.
• When converting VRayBlendMaterials, certain non-bakeable parameters are now exported based on the Base material:
  • Thin-Walled flag;
  • Volume Depth;
  • Fog Color;
  • Emission Multiplier.
• Fog color/attenuation color is now taken into account for reimported VRay materials into Shell shaders.
• Fixes issues with multipliers during material simplification inside the DCC.
• Fixes issues with VRayDisplacementModifier baking into geometry, when using multimaterials and multi-uv channels.
• Fixes issues with Cloth modifier conversion.
• Gradient and Gradient Ramp nodes are now classified as Functional Texmaps.
• Scenes with repeated names are checked before batch processing starts, rather than during.
  • As a result, statistics for "skipped" scenes are no longer reported at the end of the batch.
• The performance and memory usage of certain Image operations have been improved.
• Fixes issue with material multiplier mixing for 1-channel images.
• Fixes issue with log file being overwritten by a blank file.
• Known Issues:
  • Certain refractive materials have artifacts around their UV edges. A fix is being investigated.

Version v0.11.2

• Major internal refactoring and optimization of Translation procedures:
  • The translation procedures are now unified across the different material levels.
• The reimport of glTF Files into the output Max file has been revamped:
  • An additional, simplified, VRay shader is now created in addition to the glTF Material;
  • This is due to 3ds Max limitations and issues with rendering glTF Materials on VRay;
  • Both the VRay and the glTF material shaders are plugged into a Shell Material, for easier export and rendering;
  • The Shell Material is compatible with the Autodesk glTF Exporter.
• Introduces a threshold for Opacity and Transmission:
  • Materials that are very close to being Opaque (or non-Transmissive) will be considered so, preventing rendering issues;
  • This threshold is fixed in 5% and currently can't be adjusted.
• Introduces Texture to Color simplification:
  • Textures that are identified to be a single color will be converted into color values.
• Revamped Treatment of VRayDisplacementModifier when --bakeDisplacementis off:
  • Only one VRayBumpMtl is now created for each modifier instance, per base material.
  • VRayDisplacementModifiers of types 2D and SubDivision, which are unable to be baked, will now always be converted into VRayBumpMtl materials.
• Fixed issues with multipliers on simple materials.
• Fixed an issue with Bump to Normal map conversion on simple materials.
• Fixed an issue where materials were overly transparent.
• The gamma correction treatment has been revamped:
  • As a result, several gamma correction issues have been solved, especially on simple materials.
• New metadata files for the scene and/or batch of scenes are now saved in the output folder.
• Optional MaterialX creation has been disabled due to the Translation changes:
  • As a result, the experimental flag --createMtlx has been removed.
• Implemented a new Python glTF loader library:
  • As a result, the pygltflib dependency has been removed.

Version v0.11.1

• The creation of additional output files (GLB, USDZ, FBX, GLBOpacity) is now handled through a new flag --additionalFormat or -f:
  • Multiple file formats can be provided to -f/--additionalFormat at once.
  • Example usage:
    • --additionalFormat usdz glb fbx
    • -f usdz glb fbx
    • If you want to generate additional glbs and FBXs, but no USDz files: -f glb fbx
    • If you only want to generate additional FBX files: -f fbx
  • NOTE:
    • glTF files are always generated, no matter the usage of this flag or not.
    • Providing the same format multiple times (e.g., -f fbx fbx or -f fbx -f fbx) has no additional effect.
    • Providing the flag multiple times (e.g., -f fbx -f glb) overwrites the file format.
• Deactivated layers are now ignored during scene preprocessing, and its child geometry nodes removed.
• Fixes known issue from version v0.11.0, when using instances and references in the same node.
• The flag --additionalOutputs has been removed.
• The flag --generateOpacity has been removed.
• Fixes issue when multiple exporter plugins with support for FBX or glTF are installed.
• Fixes warning when clearing subobject selection on 3ds Max.
• Fixes issue introduced with version v0.11.0, with the return code being overridden.

Version v0.11.0.1

• Fixes an issue with incompatible Python dependency versions.
