It’s ok to pack diffuse maps with Texture2D.PackTextures.But when I try to pack normal maps which are in DXTnm format,it produces a gray map which is in A8R8G8B8 format,So how to pack normal maps in unity?Thanks.
anyone help?
Try setting the texture type to Advanced in the texture importer (in the inspector when you have the texture selected) and switch on the Read/Write Enabled option.
