A simple utility that cleans up unused bone references on your Skinned Mesh Renderers, potentially providing a performance boost in ChilloutVR.
- Import
- Upload
This is a non-destructive tool that automatically hooks the ChilloutVR CCK avatar build event. This will not modify your original source mesh- at the cost of potentially making upload slower.
ChilloutVR's specific head-hiding technique is used to avoid the need for a dedicated Mirror Clone. This involves activating a specific flag on the skinned mesh, triggering reskinning during each camera render while the avatar is worn. However, this approach can impact performance severely depending on environment and how many cameras can currently see your local avatar. To mitigate this, ChilloutVR filters out any mesh not needing this performance-intensive flag by checking against the SkinnedMeshRender.bones array to determine if it has any bones actively being hidden.
Previously, older Unity versions automatically excluded bones without weights when importing a new model. Yet, modern avatars inexplicably reference all bones by default, even those irrelevant to the model. Basically- this makes ChilloutVR assume every skinned mesh is in need of head-hiding, which can kill the local performance of your avatar.
This tool preprocesses your avatar automatically on upload, eliminating unnecessary bone references and weights, on the copy of your avatar that is uploaded to ChilloutVR. This allows the head-hiding to only run where needed and as such can greatly improve the performance of your avatar by reducing unneeded overhead while skinning between cameras.
This is not a magic bullet to increase your performance in-game. You are still likely to be bottlenecked elsewhere while in a populated instance, and as such, the performance improvement may not be as noticeable as expected.
The Visual Clone experimental option within ChilloutVR also provides a better solution than this, as it allows the head-hiding to function without the expensive reskinning flag enabled in the first place.
