about the power of 2 thing, P6 might have it different the texture size setting in render settings isnt power of 2 but again, might mean nothing at all, just random thought monitoring memory during some renders would show also most skin textures i've seen (especially lately) seem to just be 1 ratio of colors, as red changes, so does green and blue by same amount, to keep the ratio the same thats why i've been using greyscale maps in my work greyscale seems to render faster, and much less memory and just feed it into a colored input instead of pure white speed might be due to i saved maps as 8 bit greyscale so 1/3 the info needed, one thing i do know, texture loading is faster lol well duh but anyways
