d4rkpl4y3r Avatar Optimizer 2.2.0-beta.4

Features

• Add option to apply optimization on upload instead of creating a copy of the avatar.

• Fix parser not recognizing #include directives with <> instead of "". (more)
• Fix optimizer ignoring [gamma] tags for properties. (more)
• Add safeguards around bindpose & bone count mismatch. (more)

d4rkpl4y3r Avatar Optimizer 2.1.1

Install in VCC by adding the https://d4rkc0d3r.github.io/vpm-repos/main.json repo url as a custom repo in the settings.

Bug Fixes

d4rkpl4y3r Avatar Optimizer 2.1.0

Install in VCC by adding the https://d4rkc0d3r.github.io/vpm-repos/main.json repo url as a custom repo in the settings.

Features

• Add option to keep MMD blendshapes intact. (more)

Bug Fixes

• Apparently sampler is also a way to declare a SamplerState. So now the optimizer also replaces those.
• Parse and ignore const keyword in shader function parameters.

d4rkpl4y3r Avatar Optimizer 2.0.0

Install in VCC by adding the https://d4rkc0d3r.github.io/vpm-repos/main.json repo url as a custom repo in the settings.

Features

• Add option to merge simple toggles in the fx layer into one big direct blend tree.
• Optimizer is now a VPM & UPM compatible package.
• A crash in the optimize function will now show an error message that when clicked opens a link to the github issue tracker.
• Add option to merge blendshapes that get animated in a fixed ratio to each other.
• Remove blendshapes that only have animations animating them to 0 if the initial weight on the mesh is also 0.
• Show change in total blendshape count under the perf rank change section.
• Add warning if the avatar has extra animators. The optimizer only supports the custom playable layers.
• Add warning if the avatar has layer masks in the animators and the delete unused gameobjects option is enabled.

Changes

• Texture Compression Analyzer now only shows SSIM by default to reduce clutter.
• Detect DPS penetrators and stop them from getting merged into other meshes.
• Merge static meshes as skinned meshes now only merges if it results in a decrease in material count.
• Foldouts can now be toggled by clicking on the label text too.
• Delete unused GameObjects is now disabled by default if the avatar has any layer masks in the animators.
• Remove #pragma skip_optimizations from the generated shaders.
• Progress bar updates continuously while shaders get parsed.

Bug Fixes

• Fix ring finger to foot collider having half the size from VRChat update 2023.1.2.
• Fix crash when a material swap gets merged into a blob of meshes and its mesh index is non-zero. (more)
• Fix always converting vertex colors to full float32 instead of using unorm8 if it was already unorm8.
• Fix crash when eye look blendshape IDs were greater or equal than the actual number of blendshapes.
• Fix jaw flap blendshape getting deleted.

d4rkpl4y3r Avatar Optimizer 1.10

Features

• Add debug view to show all animated material property paths.
• Several small improvements to the generated shaders and mesh layouts reducing the amount of VRAM used by the optimized avatar.

Changes

• Show original mesh paths in the _IsActiveMesh properties of merged materials.
• Don't inject animated property arrays for merged material properties where none of the original meshes had that property animated.
• Calculate min and max mesh id for each merged material and only add animated property arrays for that range.
• Only add the animated property based on the used mesh indices for the merged material.
• Interleave animated property arrays in cbuffer to reduce the required cbuffer size.
• Pack original meshID & materialID into uv0.z instead of having them separate in uv0.z & uv0.w. Miniscule VRAM savings. (more)
• Call Mesh.Optimize() on the merged mesh to reduce the amount of memory it takes up. (more)

Bug Fixes

• Delete shader properties that start with _ShaderOptimizer from the optimized shader. This is to prevent Kaj shader optimizer from trying to optimize the shader again.
• Fix RemoveIllegalComponents() being broken when the sdk was imported via VCC.
• Change signaling value to NaN. This fixes animated properties interpolating the signal value weirdly.
• Create optimized swap materials after merging materials instead of before so that Texture2DArray and animated properties are correctly set.
• Deduplicate optimized swap materials with the optimized material that is already in the mesh renderer.
• Fix vertex shader not passing along mesh id to the geometry shader if the mesh id is disabled.

d4rkpl4y3r Avatar Optimizer 1.9

Features

• Multiple performance improvements that reduce the time it takes to optimize an avatar by a factor of around 2x.

Changes

• Instead of doing a AssetDatabase.Refresh() to import the optimized shaders it now uses ImportAsset() inside a StartAssetEditing() and StopAssetEditing() block. This saves a tiny bit of time.
• Replaced two heavily used regex with string and char operations. This saves a bit of time.
• Moved most of the generated shader code into include files. This saves a lot of time when importing the shaders.
• Strip [Drawer] attributes from the generated shader code. This saves a significant amount of time when assigning the shader to a material.

Bug Fixes

• Fix that the optimizer would try to merge textures with different mip count.
• Fix crash when the avatar has a component with a missing script on it.

d4rkpl4y3r Avatar Optimizer 1.8

Features

• Add info text if any normal maps are found that are not using BC5 compression.
• Add button to automatically convert all normal maps to BC5 compression.
• Add Texture Compression Analyzer under the Tools/d4rkpl4y3r/Texture Compression Analyzer menu.

Changes

• The optimized animator controllers now have (OptimizedCopy) appended to their name.
• Add Limitations section to the readme to clarify that avatars might look broken if shaders are disabled. (more)
• Slight blend shape download size reduction by setting delta values to 0 if they are below 1e-8.

Bug Fixes

• Fix parents of animated transforms getting deleted. (more)
• Always enable SkinnedMeshRenderer component that gets other meshes merged into it. (more)
• Ignore Renderers that have no materials. (more)
• Only add #define KEYWORD to passes that have a corresponding #pragma shader_feature in the pass. (more)
• Fixed that multiple vert/geometry/fragment shader declarations would cause the optimizer to only use the last one.
• Add Texture2D.GetDimensions(uint mipLevel, out float width, out float height, out float numberOfLevels) and the uint variant overloads to the merged texture wrapper class. (more)
• Fix assumed default vertex color to be white instead of black.
• Ignore Renderers that have no mesh. (more)
• Vector4 properties now use G formatting instead of the default unity F1 formatting. (more)

d4rkpl4y3r Avatar Optimizer 1.7

Bug Fixes

• Fix optimizer not working with VRCSDK3-AVATAR-2022.10.12.21.07 SDK onwards. (more)

d4rkpl4y3r Avatar Optimizer 1.6

Features

• Optimizer now shows a progress bar dialog when optimizing an avatar.
• Add info box if build target is Android to tell users that the optimizer doesn't support Quest avatars.
• Add validation check that checks if the optimizer got added to an optimized copy.
• Add validation error if the amount of base playable layers isn't 5.

Bug fixes

• Fix extra out parameters in the fragment shader not getting added to the function declaration. (more)
• Add ParserException if any parameter in vertex or fragment can't be parsed.
• Fix parsing of template types to permit spaces between the type and the template brackets.
• Fix new lines in string literals not being the environment's new line character. This caused shader warning spam on poi shader.
• Fix default texel size to 4 instead of 8. This matches the sizes of the default textures as checked with nvidia nsight.
• Fix non float params not working with "Keep Material Animations Separate" option.

d4rkpl4y3r Avatar Optimizer 1.5

Bug fixes

• Fix crash when an EditorOnly tagged game object was in the exclusions list.

• Fix nested BlendTrees not getting iterated through to fix animation paths.
• Move the optimized copy to the same scene as the original.
• Replace VFACE semantic with SV_IsFrontFace.
• Force include TEXCOORD0 semantic in the vertex shader input struct. This fixes cases where the sematic only exists in some shader variants.
• Don't delete transforms that are moved by animations.
• Don't delete parent transforms of Constraints.
• Deep copy blend trees when fixing animation paths.
