3point shader adds uv channels.

GIS3000

Hi there,

Does anyone here notice that the "3point quality normals" modifier adds 3 new UV channels to your model? Usually channels 3, 4 and 5.

Does this mean the in order for quality normals to work, one needs these extra channels. Don't they increase the file size and vertice count?

thanks

I believe they're there to store the custom tangent space used to display quality normals

and yes, it will add to the overall cost of the object but it's not significant in max terms and you'll strip it all off before exporting to an engine if you don't need it.
