◆ multires_ensure_external_read()

void multires_ensure_external_read	(	Mesh *	mesh,
		int	top_level )

Makes sure data from an external file is fully read.

Since the multi-res data files only contain displacement vectors without knowledge about subdivision level some extra work is needed. Namely make is to all displacement grids have proper level and number of displacement vectors set.
