By default, processing of model files (like FBX) automatically convert the included materials to Atom materials, using StandardPBR. This adds a job dependency on StandardPBR.materialtype, which propagates to any related azsl files as well. Thus any change to azsl code will cause all model files in the project to rebuild.
Some game teams have no interest in using the auto-converted materials; they always use a Material Component to apply material overrides for every mesh. This new setting allows teams to disable material auto-conversion for the entire project, thus removing the job dependency on StandardPBR.materialtype. Instead, every mesh will be assigned the same default material. Any change to azsl code will cause that one default material to rebuild, but this will not trigger any models to rebuild.
Details:
- Added /O3DE/SceneAPI/MaterialConverter registry settings for configuring the scene material converter. It includes an enable flag, and a default material to use when conversion is disabled.
- Added SceneBuilderDependencyRequests::AddFingerprintInfo which allows ScenePI components to modify the scene builder analysis fingerprint. We use this to reprocess scene files when the material converter settings change.
- Updated SceneAPI's material asset builder to skip the StandardPBR dependency when material conversion is disabled.
- Added some code to MaterialComponentController to handle an edge case that may when disabling material conversion on an existing project, and assigned materials disappear.
Testing:
- Changing the registery setting does trigger a rebuild of the fbx files.
- When material conversion is disabled, changing an azsl file does not cause fbx files to rebuild, but the shader still reloads as expected.
- Made a test level using multiple models with multiple meshes, made various adjustments to the material slots for each mesh, and tried switcihng the material conversion registry setting from true to false. (Details below)
- TODO: Will merge this change to a customer's fork and test on their existing content.
Details about my test level:
- Made a new test level AtomTest project
- Added two entities, both using multi-mat_mesh-groups_1m_cubes.fbx
- Added a material component to both entities
- Entity 1 material assignments
- Blue_Zaxis: left as-is
- Green_Yaxis: exported the material
- Red_Xaxis: exported the material, and changed the material instance color to pink
- StingrayPBS1: exported the material, scaled the UVs in the exported material source, and changed the material instance color to green.
- With_Texture: selected an existing brick material, changed the material instance color to red.
- Entity 2 material assignments
- Default Material: set to an existing brick material
- Blue_Zaxis: manually assigned built-in material that was converted from fbx
- Green_Yaxis: manually assigned built-in material that was converted from fbx, and changed the material instance color to orange
