public int GetVertexAttributeStream(VertexAttribute attr)
Parameters
The vertex data attribute to check for.
Returns
Type | Description |
|---|---|
| int | Stream index of the data attribute, or -1 if it is not present. |
Remarks
Meshes usually use a single vertex buffer stream, but it is possible to set up a vertex layout where attributes use different vertex buffers (see Mesh.MeshData.SetVertexBufferParams). When you use such a layout, use this function to query which vertex buffer stream a given attribute is part of.
Note that this function returns the index of the stream, without specifying where the attribute is within the stream. To identify the location of a given attribute in the stream, use Mesh.MeshData.GetVertexAttributeOffset.
