Problems with NVidia Photoshop Normalmap Plugin

Steve Schulze

I've been experimenting with this tool a bit but can't seem to get any result that looks much like a normal map. The only colour that comes through is the blue with very subtle gradations on varying levels of my height map.

Looking through related websites and tutorials, I don't think I'm doing anything wrong and should be getting a decent looking normal map out of this.

Any suggestions as to where I'm screwing up?

Pior gives help!

That may help. You can't make a full normalmap just by painting a greyscale and running it through the filter.

You have to change it to Overlay mode on top of your base normalmap, set the blue channel's levels to 127 instead of 255, collapse that and run the filter again set to Normalise.

Ah, I knew I'd seen a proper tutorial around somewhere. That seems to have worked quite well. Thanks Mop and thanks Pior.
