public int GetVertexAttributeDimension(Rendering.VertexAttribute attr);


attr Vertex data attribute to check for.


int Dimensionality of the data attribute, or zero if it is not present.


Get dimension of a specific vertex data attribute on this Mesh.

Meshes usually use a known format for data layout, for example, a position is always a 3-component Vector, and a tangent is always a 4-component Vector. But, in some cases (usually regarding texture coordinates), the data layout can be of different dimensionality. For example, SetUVs accepts either a 2D, 3D or 4D texture coordinates. You can use this function to query this layout.
