: How do I reduce noise in a normal map with Photoshop? I'll be straightforward: I want to create a normal map resembling this from this texture: I've been at it for about an hour, and

There’s only two ways I know to make a normal map — from a vector model or from a height map. Since you have a photo as a starting point, a height map is your best option.

You can probably fudge a decent height map by copying a channel and applying levels to it, because the dark areas are also the recessed areas.



From there, you’ll have to convert the height map to a normal map.

If you’re on a PC, NVIDIA have a Photoshop plugin available: developer.nvidia.com/nvidia-texture-tools-adobe-photoshop
This tutorial seems good, but I can’t vouch for it’s accuracy: www.moddb.com/groups/udk-developers-group/tutorials/ao-and-normal-maps-from-a-height-map
Or, you’ll have to use some other method (there are quite a few tools available for the task).
