SMR: Skinned Mesh Renderer (built-in)\
IcaSM: Ica Skinned Mesh (this asset)\
Ica Skinner: Main Component of the asset\
LBS: Linear Blend Skinning (Built-in skinning)\
DQS: Dual Quaternion Skinning

<mark style="color:purple;">Q: Is it faster than built in SMR?</mark>\
A: It depends, SMR and Ica Skinner have different performance characteristic. In most cases when more than 8 blend-shapes are active, Ica Skinner start outperforming SMR.

<mark style="color:purple;">Q: Does it use more vram than SMR?</mark>\
A: Unfortunately yes, due to some limitations of mesh API, some data need to be duplicated and this result of higher vram usage. While it may seems a lot, it will be not significant unless you have hundreds of Ica Skinner actives at the scene.

<mark style="color:purple;">Q: Does it reduce asset size?</mark>\
A: Yes, since Ica Skinner recomputes normals and tangents real-time, it does not need the mesh normals-tangents and blend shape delta normals-tangents. This significantly reduce asset size.

<mark style="color:purple;">Q: Can be used by “X Asset” together?</mark>\
A: If X asset work with the internal buffers of SMR (GetVertexBuffer etc), then probably no.

<mark style="color:purple;">Q: Does Cloth Component works?</mark>\
A: No. Same reason above.
