Make attribute layout non-interleaved. Warning! This does not change data layout! Use direct buffer access to fill the data. This is for advanced usage.

De-interleaved data means all attribute data for each attribute is stored continuously like this: 000011112222 instead of: 012012012012

Note

This is per attribute de-interleaving, NOT per component.

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.

Warning

Always add a prefix to the result of this function as the generated string can start with a number and not be a valid attribute name.
