Adding a factor for alpha affecting specular in the standard and enhanced pbr materials (#1474)
* Adding a factor for how much alpha should affect specular to standard and enhanced pbr. Currently blended and tinted transparency always assume that the geometry represents the surface, and the surface may just be transparent like glass. In this model, specular is unnaffected by alpha - perfectly clear glass still reflects light and obeys the Fresnel factor. However alpha may also represent the absence of a surface entirely for mateirals where cut-out alpha is a bad fit because of subpixel detail, like hair or cob webs. This change addresses that by allowing the alpha to also affect specular reflection if desired.
* Adding material for ASV test.
[ATOM-14344][ATOM-13908] Merging skinned and static mesh motion shaders using an optional vertext stream. This removes the log spam "Mesh does not have all the required input streams. Missing 'POSITIONT0'." and allows Material::GetShaderCollection() to be const only as it was intended. The MeshFeatureProcessor also no longer needs to decide which motion vector shader to use, and therefore no longer has m_skinnedMeshWithMotion in the descriptor to acquire a mesh.
- Renamed "Details" group to "Overview".
- Renamed "UV Names" group to "UV Sets".
- Renamed "General" group to "General Settings".
- Renamed "Parallax" group to "Displacement".
- Renamed "Texture Map" properties to just "Texture". In cases where a specific type of texture is mentioned like "roughness texture map" I called this "roughness map" (which is more common according to google).
- Renamed "Heightmap" to "Height map" (which is more common according to google).
ATOM-14002 [Material Editor] Revisit user facing organization and layout of material types
Removed the parallax invert flags and instead all the materials assume displacement is always specified as heightmaps.
Updated property naming, tooltips, and shader variable names to reflect this.
Updated ParallaxMapping.azsli to treat depthOffset as an offset in depth value rather than an offset in height value, so it matches the fact that ParallaxMapping.azsli always operates in depth values rather than height values.
The only remaining unnecessary enable flag I found was for the parallax property group. It is removed, and now we just use the texture map and useTexture flag to gate whether the feature is enabled.
Copied tinted transparency opacity mode from EnhancedPBR to StandardPBR.
Fixed a bug in EnhancedPBR where Blended opacity didn't work right because the second DrawListOverride functor was stomping on the results of the first DrawListOverride. I removed these functors and made StandardPBR_HandleOpacityMode.lua set the draw list override instead.
Updated material type files for StandardPBR, EnhancedPBR, and Skin to align with each other as much as possible.
There were minor cases like some property settings were different, properties in different order, comments, and formatting.
There were major cases as well, like EnhancedPBR using clunky built in functors where lua functors would be better, property visibility state wasn't right, properties were missing, etc.
I also added a new HasShaderWithTag function for lua functors. This is used in StandardPBR_ShaderEnable.lua to allow this script to be used for both StandardPBR and EnhancedPBR (EnhancedPBR doesn't have the low end pipeline shaders).
Updated material types to have default parallax settings of POM, Low quality, 0.05 scale. That way the parallax effect will show up as soon as a user adds a heightmap.
Updated StandardMultilayerPBR_Displacement.lua to control the o_parallax_feature_enabled, so we can have the material's parallax.enable=true by default. Again this is to allow parallax behavior to show up as soon as the user adds a heightmap or adjusts the displacement offset. Note that even though we have a functor to drive the feature based on displacement settings, we still need the parallax.enable flag that that the user can set to false when they want to use displacement blending but not parallax.
Updated test materials to maintain their prior implied settings.
Added a loop to the skin shader that will sample from wrinkle masks, multiply them by a weight, combine them, and use them instead of vertex colors for wrinkle map blending
Added an array of masks, an array of weights, and a wrinkle mask count to the DefaultObjectSrg. -Will create a follow up task to handle this a better way.
Removed motion vector (for now) from skin.materialtype since we're not using them, and removed depthtransparent since skin doesn't support transparency
Added an interface to the MeshFeatureProcessor to get the object srg
Wrapped srg->Compile in if(srg->IsQueuedForCompile()) to prevent compiling twice --This doesn't stop a race condition if both happen at the same time, but that is at least far less likely. It will need a better solution later.
Added a function to the MorphTargetExporter that will check to see if a texture that matches the blend shape name exists in a particular folder, and adds a reference to that image to the MorphTargetMetaAsset --Only supports .tif, and doesn't automatically re-process the .fbx if the folder is updated. These can be improved in later iterations
Added a null check in MaterialTypeSourceData.cpp to fix a crash I ran into
Added a for loop in two places to look for the first submesh that has a morph target, instead of just using the first to check if a lod has morph targets or not. --I have a better fix for this, but it involves more areas of the code, so I'm saving that for another change.
Modified AtomActorInstance to look for any morph targets that have a wrinkle mask reference
Then each frame, for any morph targets with non-zero weights that also have wrinkle masks, it updates the mask array, weights, and count on the object srg.
