A unity tool to reduce the amount of clipping between clothing layers and characters by hiding areas of the mesh which are occluded by outer layers.

Note: if duplicate unsafe.dll's are detected, reload vrchat sdk to fix
Still getting error:

Works very well, small issues with certain areas such as armpits as described below.
-
Download the project
-
Open the Scene "Character Clipping Test Scene"
-
Reset the meshes on the occlusion pawn to default
-
Run the "Character Clipping Protector" - Check button - on "HumanMesh_WITHCLIPPINGPROTECTOR"
-
Adjust the sliders for differing results
-
Fast - could be potentially used sparingly realtime depending on the mesh
-
Good coverage - Gets most areas and flat/slightly rounded surfaces
-
Complex areas - Areas such as the armpits/ inner thighs can be an issue due to the huge variance in angles
-
For large meshes will cause perforance isues
-
Async- must be run in a coroutine
-
Only setup for skinned meshes
-
DO NOT RUN in any pose other than T or A pose - will get varying results
-
Setup a specific layer for testing occlusion and set this in the script
-
In editor use the "check" option as described above to run the simulation
-
To run from code simply set the meshes and then start the RunClippingSimulation coroutine (with optional callback when complete)
-
Adjust margin to add "safety" margins where the edges of the mesh occur
-
ORDER MESHES in terms of layer with the lowest priority first in the inspector (see example)
-
Split meshes up if required: The script will do a reasonable job on all areas but manual culling could be required in certain situations (split arms/legs/torso/head etc)
-
Calculate all mesh combinations upfront in a loading phase and store the results with the "Caching" feature - will then allow quick culling later during gameplay
-
Creates a seperate collider mesh to test against for each mesh
-
Uses the new Raycast command to cast for each vertex on each mesh from the outside in
-
Collects results and processes to find areas with overlap
-
Creates a new mesh and hides areas with signigicant overlap
- Use the debug options on the tool to show either mesh hits (overlapping zones) or every raycast made.
