◆ GPU_vertformat_multiload_enable()

void GPU_vertformat_multiload_enable	(	GPUVertFormat *	format,
		int	load_count
	)

Makes vertex attribute from the next vertices to be accessible in the vertex shader. For an attribute named "attr" you can access the next nth vertex using "attr{number}". Use this function after specifying all the attributes in the format.

NOTE: This does NOT work when using indexed rendering. NOTE: Only works for first attribute name. (this limitation can be changed if needed)

WARNING: this function creates a lot of aliases/attributes, make sure to keep the attribute name short to avoid overflowing the name-buffer.
