1.8.2 - 2024-12-11 #

Added #

• - button for prefab safe set #1368

Fixed #

• Errors with models with UV at very edge #1363
• Errors if exactly same AnimatorController is specified for multiple playable layers #1366
• Errors if objects removed by some component is listed on exclusions of Trace and Optimize #1367
• OverflowException when creating prefab #1369

1.8.1 - 2024-12-01 #

Fixed #

• Optimize Texture may break liltoon outline mask #1357

1.8.0 - 2024-11-30 #

Added #

• AnyState to Entry/Exit optimization in Optimize Animator #1157
  • If AAO found animator layer only with AnyState, AAO tries to convert them to Entry / Exit pattern.
    • Currently due to implementation there are some patterns that can be convert but but not converted.
    • We may relax some restriction in the future.
  • Because we have to check for each condition if we use AnyState but we can check for only one (in best case) with entry/exit, this generally reduces cost for checking an parameter in a state.
  • Combined with Entry / Exit to 1D BlendTree optimization, which is implemented in previous release, your AnyState layer may be optimized to 1D BlendTree.
• Optimize Texture in Trace nad Optimize #1181 #1184 #1193 #1215 #1225 #1235 #1268 #1278 #1313 #1328 #1338 #1334 #1346
  • Avatar Optimizer will pack texture and tries to reduce the VRAM usage.
  • Currently liltoon is only supported.
• Copy Enablement Animation to Merge Skinned Mesh #1173
  • This feature copies activeness / enablement animation from merge target renderers to the merged renderer.
  • This feature is not enabled by default. You have to enable it in the inspector.
  • This feature supports copying activeness animation of activeSelf of the GameObjects or ancestors of the GameObjects. However, this feature does not work if multiple GameObjects (or both GameObject and Renderer itself) are animated.
  • In addition, this feature will be animate the enabled of the merged renderer, so you must not animate the enabled of the merged renderer.
    • If animations are unsupported, AAO will show an error message and abort the build.
• Support Read/Write disabled Meshes with Av3Emulator Enabled #1185
  • Previously, AAO cannot process meshes with Read/Write disabled if AAO is triggered by Av3Emulator.
  • Since this release, AAO can process meshes with Read/Write disabled if AAO is triggered by Av3Emulator.
  • In addition, AAO now supports non-Float32 vertex buffers.
    • We still use Float32 internally so Int32 data might lose precision a little.
    • However, AFAIK there is no real-world problem with this so we implemented this way.
    • If you found such a case, please report it.
  • This change make AAO incompatible with Unity without Graphics.
    • If you’re building your avatar with batchmode with -nographics, please remove -nographics.
• Asset Description for Avatar Modify Support bundled in an avatar, Shinano #1189
• API to get in advance whether a polygon will be removed #1177
• Rename BlendShape component to rename BlendShapes #1245 #1296
  • This can be used to avoid blendShape name conflicts in Merge Skinned Mesh
• Invert option for Remove Mesh in Box #1257
  • You now can remove polygons outside of the box instead of inside the box.
  • Along with this new feature, we renamed Remove Mesh in Box to Remove Mesh By Box to make it more clear.
    • This doesn’t change the class name of the component since it’s already a part of the public API.
• Remove Mesh By UV Tile, a new way to remove polygons #1263
  • You now easily remove some polygons of models configured for UV Tile Discard.
  • This component removes polygons like UV Tile Discard with Vertex Discard Mode.
• Automatically remove unnecessary material properties based on shader #1041
  • This feature is added to Remove Unused Objects in Trace and Optimize.
  • When you changed shader for an material, properties for previously used shaders might be remain
  • This may increase your avatar size by unexpectedly including unused textures
• Right-click menu option to create a new GameObject with a specified component #1290
• Automatically Merge Blendshape #1300 #1324
  • This is new automatic optimization in Trace and Optimize
  • This is a part of “Optimize BlendShape” optimization.
  • AAO 1.8.0 introduced BlendShape support for Merge Skinned Mesh, but new default mode “Rename to avoid conflicts” would increase number of BlendShape.
  • This feature is added to relax this problem by automatically merging multiple BlendShapes of one Mesh.
  • With this feature, you can use rename mode without performance loss.
• Fix mode for PhysBone Limits in Merge PhysBone #665 #1336 #1345
  • In addition to existing Copy and Override, we added Fix mode.
  • This mode will try to correct roll axis by rotating bone.
  • This feature allows you to configure the mode for PhysBone Limits in Merge PhysBone.
  • This is useful if all configuration is same but roll axis is different.
• Automatically merging meshes which have BlendShapes #1308
  • In previous version of Avatar Optimizer, meshes which have BlendShapes are not automatically merged.
  • This was because BlendShape manipulation load is proportional to the number of vertices in Unity 2019.
  • However, in Unity 2020 and later, BlendShape manipulation load is mostly proportional to the number of moving vertices.
  • This means that increasing the number of vertices in a mesh which has BlendShapes does not increase the load of BlendShape manipulation much.
  • Therefore, we decided to automatically merge such meshes.
• Improved OSC Gimmick Support #1306 #1351
  • We added two information for OSC Gimmick in Asset Description.
  • By defining parameters read / written by OSC Gimmick, your OSC Gimmick no longer breaks.
• Automatically Merge Material Slot #1334
  • If you have multile material slots with same material, it will be merged automatically.

Changed #

• Skip Enablement Mismatched Renderers is now disabled by default #1169
  • You still can enable it in the Inspector.
  • This change does not affect the behavior of previously added components.
• Use UInt16 index buffer if possible even when total vertex count is more than 2^16 #1178 #1255
  • With baseVertex in index buffer, we can use UInt16 index buffer even if total vertex count is more than 2^16.
  • Of course, if one submeh references wide range of vertices, we cannot use UInt16 index buffer so we still use UInt32 index buffer in such a case.
• Reimplement Preview system with NDMF Preview System #1131 #1195 #1218 #1270
  • This will prevent issues relates to Animation Mode bug.
  • This allows you to preview Remove Mesh components without selecting Mesh OR while in Animation Mode.
• Improved Prefab Safe Set, which are used in MergePhysBone, MergeSkinnedMesh, FreezeBlendShape and more components #1212 #1219 #1221 #1236 #1287 #1294 #1348
  • This should improve compatibility with replacing base prefab, which is added in Unity 2022.
• Allow multiple component for Remove Mesh components with API #1216 #1218
  • This allows non-destructive tools to add Remove Mesh components even if Remove Mesh component are added before.
• Animator Parser Debug Window now supports ObjectReference animation support #1222
• Reimplemented Animator Parser node system #1227
• Renamed debug options internally #1228
  • This will lose previously configured debug options.
  • However, debug options are not considered as Public API as stated in documents so this is not backward incompatible changes in semver 2.0.0 section 8.
• Performance Improvements #1234 #1243 #1240 #1288 #1304 #1307 #1314 #1325 #1327 #1326 #1341
• Transform gizmo are now hidden while you’re editing box of Remove Mesh in Box #1259
  • This prevents mistakenly moving the Skinned Mesh Renderer while editing the box.
• Make MergePhysBone implement INetworkID #1260
  • This allow you to configure networkid for merged PhysBone component
• Changed locale code for simplified chinese from zh-cn to zh-hans #1264
  • This would improve compatibility with other NDMF tools.
  • Many NDMF tools uses zh-hans so previously you may see both 中文 (中国) and 中文 (简体).
  • I think zh-hans is more accurate expression so I changed so.
• Improve RemoveMeshByMask compability with Tex Trans Tool #1269
• Support for Shaders that depends on vertex index #1275 #1281 #1285
  • Avatar Optimizer will not automatically merge meshes that are using vertex index
  • since merging them may change vertex order, which changes vertex index
• BlendShape support for Merge Skinned Mesh #1286 #1299
  • You now can successfully merge Meshes with BlendShape with Merge Skinned Mesh.
  • Actually, previous version does not have proper consideration for BlendShape.
  • This version introduces options to select BlendShape behavior in Merge Skinned Mesh.
• Renamed “Automatically Freeze BlendShape” to “Optimize BlendShape” #1300

1.7.1 - 2024-05-07 #

Added #

• Implement mask texture editor #1044
• Add Simplified Chinese translation #1055

Changed #

• Improved behavior with Read/Write Off #1045
  • Because of Unity limitation, AAO cannot process meshes with R/W off on Start so it will be error.
  • However, on Awake, we can read them so AAO should process them.
  • Since this version, AAO will process meshes with R/W off on Awake.
  • This reduces the number of errors on the apply on play.
  • If you’re using Av3Emulator, you still see the error.
  • In addition, in such case, we’ll show Auto Fix button on the error message.
  • If you press the button, AAO will fix the error by changing the mesh to read/write enabled.
• Advanced Options section has benn renamed to Debug Options #1052
  • This express the purpose of the section more clearly.
• Added Advanced Optimizations and moved Remove Zero sized Polygons to it #1052
  • The Remove Zero sized Polygons can break some shaders or animations so it’s not enabled by default.
  • To make it more clear, we moved it to Advanced Optimizations.

Fixed #

• Material Slot animations for multi-material multi-pass rendering are broken #1042
  • Previously we only preserves animations for the number of submeshes instead of material slots.
• Relax Bounds condition for Automatic Merge Skinned Mesh #1043
  • Previously, AAO doesn’t merge Skinned Meshes if bounds are different accurately.
  • Since this version, AAO will merge meshes if bounds are the same with precision to the last 6 digits of decimal point.
• Entry/Exit to BlendTree broken with None state 1048
• Particle System with bone-rigged Skinned Mesh Renderer will be broken #1054

1.7.0 - 2024-04-30 #

Added #

• Animator Optimizer #854
  • Most features of Animator Optimizer is not available in Unity 2019.
  • Animator Optimizer optimizes your Animator Controller without behaviour Changes
  • Current Optimizer includes the following optimization
    • Remove meaningless properties #854
    • Converts Entry / Exit to 1D BlendTree #854 #867 #927 #970 #982 #991
    • Merges multiple BlendTrees to single Direct BlendTree #870 #978 #980 #984
    • Removes meaningless Animator Layers #870
• Asset Description #847
  • Asset Description is the file to provide information of your assets for Avatar Optimizer.
  • Please see documentation for more details.
• Warning for material animation in Merge Skinned Mesh #769
  • Merge Skinned Mesh does not support animating material properties differently. (In other words, it can be broken.)
  • Since this version, AAO will warn for such a case.
  • If you animated all materials from same animations, your animation will not be warned.
• API for declaring dependency relationship to the name of the component #943
  • You can use this API to not change the name of the GameObject.
• Configuring Clamp BlendShapes (Deprecated) #957
  • Since VRCSDK 3.5.1, VRCSDK sets Clamp BlendShapes (Deprecated) to true on assembly reload.
  • This is not a good setting for AAO in EditMode since AAO does not support clamping BlendShapes.
  • That’s why AAO now configures Clamp BlendShapes (Deprecated) to false in edit mode and true in play mode.
  • PlayMode is usually used for testing the avatar behavior so it’s better to have the same setting as VRChat client.
  • If you want not to change this setting, please disable Tools/Avatar Optimizer/Configure Clamp BlendShape Weight.
• Automatic Merge Skinned Mesh #952 #972 #1010 #1020 #1021
  • Trace and Optimize now automatically merges Skinned Meshes if possible.
  • Trace and Optimize will merge your mesh if the material properties or enablement of the mesh is animated similarly and has no BlendShapes.
• Components API for Scripting Usage #976
  • You can now add AAO components from your script.
• Animations animating missing GameObject is removed #994
  • Since this update, animations that targeting GameObjects with post-AAO paths is no longer working.
  • Please create animations that targeting GameObjects with pre-AAO paths.
• Remove Mesh by Mask #998
  • With this component, you can remove polygons with mask texture.
  • You can use use mask for MeshDeleterWithTexture or alpha mask to remove polygons.
• Remove Empty SubMesh in Trace and Optimize #1007
  • This removes empty SubMeshes including becomes empty by optimization.

Changed #

• MergePhysBone now corrects curve settings #775
• MergePhysBone now warns if chain length are not same #775
• MergePhysBone with only one source is now error #775
  • It was not working well and not a error by a bug.
• Animator Parser is completely rewritten #850 #968 #1011
  • New Animator Parser allow us to track animating properties animated by components removed by AAO.
• PhysBone that swings no bones are now removed #864
  • I found such a PhysBone on Lime so I added this feature.
• Switched Localization system to NDMF from CL4EE #873
  • Since this release, Avatar Optimizer is no longer depends on CL4EE.
  • Because VCC doesn’t remove unused packages, CL4EE may still be installed on your project.
  • If you want to remove CL4EE, please remove it manually.
• Suppressed animated BlendShape warning of FreezeBlendShape if it’s animated to a few constants #881
  • Modern models have tons of BlendShapes to change their face shape but emotion animation of some of them animates such a BlendShapes to constant (default value).
  • That’s unnecessary (incorrect I think) and force users to remove or change the clip when user wants to face shape.
  • I see AAO users use FreezeBlendShapes for overriding such a BlendShapes on twitter.
  • I think using this way is reasonable enough so I suppressed the warning if AAO detected such a usage.
• Changed minimum VRCSDK to 3.3.0 #882
  • VRCSDK 3.3.0 is required for stable NDMF-VRCSDK compatibility.
• Endpoint Position settings for newly created MergePhysBone is now Copy instead of Clear #945
  • The Clear settings will increase the number of PhysBone Transforms so it’s not better as a default settings.
• Improved activeness animation warning in Merge Skinned Mesh #948
  • Reduced false-positive warnings
    • Previously, AAO warns if activeness warning is applied to different GameObjects.
    • However, this can be false-positive if animation is applied to different GameObjects with same timing.
    • Since this version, AAO will not warn if the activeness is animated in same animation clip with same curve.
  • Combined warning per Merge Skinned Mesh component.
    • Previously, AAO warns for each source Renderers.
    • Since this version, AAO creates one warning for each Merge Skinned Mesh component.
• Add error for Cloth component in Merge Skinned Mesh component #949
  • The Cloth component is not supported by Merge Skinned Mesh component.
  • In previous versions, AAO will keep the source Skinned Mesh Renderer if it’s with Cloth component by bug.
  • Since this version, AAO will make an error if the source Skinned Mesh Renderer is with Cloth component.
• Remove Unused Objects now removes PhysBones and Contact Receivers with parameters defined but not used by Animator Controllers #959
  • Previously, AAO did not remove PhysBones and Contact Receivers if they are defined in Animator Controllers whether they are used or not.
  • I thought such a PhysBones on the base body are rare but my friend told me there is Manuka has such a PhysBone so I added this feature.
• Dropping GameObject to PrefabSafeSet adds the All components on the GameObject to the PrefabSafeSet #960
  • You can add all PhysBones on the GameObject by dropping the GameObject to the MergePhysBone component.
• MergeSkinnedMesh now warns if Root Bone or Anchor Override are not set #963
• It will be error if read/write mesh is off in play mode again #1018
  • I found that we may not possible to read mesh with r/w mesh off mode in play mode with the Av3Emulator.
• Disabled AutoFreezeBlendShape for Skinned Mesh Renderers with Cloth component #1029
  • According to the report, making some polygons zero-size by AutoFreezeBlendShape will make initializing avatar extremely heavy.
  • After a small discussion, we decided to not automatically optimize Skinned Mesh Renderers with Cloth component.
