ashwin.sudhir Posted August 12, 2011 Posted August 12, 2011 Was surprised to find this in the documentation "Specular map should be without the alpha channel to avoid artifacts" Is this still a problem? What kind of artifacts might appear? Is there some other way of controlling the spec power? -a.
frustum Posted August 12, 2011 Posted August 12, 2011 You shouldn't use zero values in alpha. Alpha zero areas cause NaN values in rendering pipeline.
ashwin.sudhir Posted August 16, 2011 Author Posted August 16, 2011 Guess this is a documentation bug then; it should probably read (if I understand it right): "Specular map should be without *zero in* the alpha channel to avoid artifacts *on DX10 renderers*" -a.
