- numBones (numMatrices)
- Number of bones attached to the skin, also the number of inverse matrices (see skinToBoneMatrices).
- numUsedBones
- Number of bones which influence vertices, that is those bones which have at least a non-zero weight. If this value is zero, RW will try to find "used" bones automatically.
- maxWeightsPerVertex
- Overall number of maximum non-zero weights per vertex. If zero, RW will find this value automatically.
- bonesUsed
- Indices list of the significant bones connected to the skin (see numUsedBones).
- vertexBoneIndices
- Vertex bone indices are represented with 4 bone indices per each vertex.
- vertexBoneWeights
- Vertex bone weights are represented with RwMatrixWeights structure per each vertex. RW docs says it's necessary to keep the order within 4 weight values (from higher to lower), but even some example models have different ordering.
- skinToBoneMatrices
- These are inverse matrices represented with RwMatrix structure.
- boneLimit
- numMeshes
- numRLE
- meshBoneRemapIndices
- meshBoneRLECount
- meshBoneRLE
