We use square pixels in our textures, even when the output is non square. The only time that’s not done is when we’re working with non square source texture.
Well, that’s fine, but what if you want layer effects (such as glows) which are proportional to the non-square pixels in your output? I you know a texture will be used 2:1, for example, then you’d like a bevel or emboss or shadow to be scaled 1:2 in the source.
No, layer styles are not going to easily handle non-square aspect ratios. Too many of the calculations are based on distance between pixels, and would be very, very difficult to make work in non-square pixels.
Thank you Chris. I suspected it was so, but now I can stop looking for a solution other than flattening and rescaling.
