There were two issues fixed here. First, I broke the material inspector with my changes at 53188a12da which added support for hiding entire property groups. I'm not sure how this happened because I definitely tested the MaterialComponent's material inspector. Perhaps there was a bad merge or something otherwise got clobbered after testing and before committing. Anyway, this issue was I accidentally delete the code that prepared the list of material properties for functor processing.
The second issue was the MaterialFunctor class needs to return null when metadata can't be found; it was proceeding to dereference an end iterator.
Testing:
Successfully opened the material inspector through the MaterialComponent. Was able to change property flags in the inspector and see other properties change visibility as expected.
Cleaned up code around MaterialFunctor's QueryMaterialPropertyMetadata and QueryMaterialPropertyGroupMetadata.
Removed unnecessary "groupHeader->setObjectName(...)"
Simplified code in MaterialInspector::OnDocumentPropertyGroupVisibilityChanged.
ATOM-14688 Disable Individual Layers
- Added new SetMaterialPropertyGroupVisibility functions to the material functors.
- Updated the MaterialFunctor::EditorContext to include parameters for handling material property group metadata.
- Updated the material inspector(s) to apply the property group visiblity changes from the material functor, to hide or show the property groups.
- Moved some code from MaterialPropertyDescriptor.h/cpp to a new MaterialDynamicMetadata.h/cpp, since these aren't really related to the MaterialPropertyDescriptor code. It's more for material functors to use.
- Also fixed the casing for the "GetMaterialPropertyValue_Image" lua function, since I was already in this code (ATOM-14793 "Fix Inconsistent Casing For LuaMaterialFunctorRuntimeContext")
Tested in MaterialEditor and in in the main Editor's MaterialComponent property override inspector.
