Synopsis

Mesh:attachAttribute( name, mesh, step, attachname )

Arguments

string name

The name of the vertex attribute to attach.

Mesh mesh

The Mesh to get the vertex attribute from.

VertexAttributeStep step ("pervertex")

Whether the attribute will be per-vertex or per-instance when the mesh is drawn.

string attachname (name)

The name of the attribute to use in shader code. Defaults to the name of the attribute in the given mesh. Can be used to use a different name for this attribute when rendering.

Notes

If a Mesh wasn't created with a custom vertex format, it will have 3 vertex attributes named VertexPosition, VertexTexCoord, and VertexColor.

Custom named attributes can be accessed in a vertex shader by declaring them as attribute vec4 MyCustomAttributeName; at the top-level of the vertex shader code. The name must match what was specified in the Mesh's vertex format and in the name argument of Mesh:attachAttribute.
