# Skinned Meshes

## SkinnedMesh Rootpart Name Limitation

Skinned Meshes with PrimaryPart named "HumanoidRootPart" will not animate the root bone correctly\

## 4 Bones per Vertex Maximum

Skinned Meshes have a maximum of 4 bones per vertex, anymore will be ignored.\
\
This is because there are always 4 bone slots reserved per vertex for skinned mesh rendering at any given time, this number is static so attempting to allocate past the 4th one will just cause the data to be ignored.
