hey guys, so ive been having trouble learning how to make "good" normal maps using the normal map filter from nvidia toolkit in photoshop. This is the method most other modders use, correct?
Ive watched/read a few tutorials and basically what im doing is running the filter once with the 'scale' value set anywhere from 2-10, and then select either "4 sample" or "9 x 9" in the height generation section of the filter dialog.. then i leave everything else where it is ("add height to normal map" selected, "animate light" selected in 3D View Options section of the dialog, "Average RGB" selected in Height Source, and "Height" selected in Alpha Field)
Then after i apply the filter the first time, i duplicate the layer, apply some gaussian blur to it, choose "overlay" blending mode, and merge down. Then I repeat this a few times.. this is how im adding more depth/height to the map. .. and thats about it.
basically what ive been doing for practice is taking the textures from various popular mods and trying to replicate the normal map using their regular (diffuse) maps... but it seems i just cant get them quite the same.
Does anyone have any advice for me? It would be greatly appreciated
