You can build Bump and Specular maps easy from within Poser using Math_Functions nodes.įor Specular Maps => True White is max Specular, and true BLACK is NO Specular.įor Bump Maps => True White is max Bump, and true BLACK is NO Bump. 005 setting will get you to see what i mean, but ive never used anything past. this gives me a good render of wht bump with no colors so I can see if it need to be cranked up (value) or down. What I do, is i unattach the texture node in the material room, and play with and adjust the bump on the model before I even attach the texture. ĥ in poser, open the bump, connect to the 'bump' or 'displacement' nodes. (here, the moles and raises on skin always seems to be white(r) now, which is what you want.Ĥ save and name whatever -just add 'bump' to the original file name, and stick it where ever the file name is.

but through trial and error, ive learned that the best result is this that Ive found for what I like.ġ open your texture imgage in a photo editor,ģ change image to NEGATIVE. I have been playing P6 for a bit on this. Of course you don't need to use every shade of grey, you can decided what steps to use by your choice of grays. I think of it as a topographical map with 255 layers, black is sea level, grey shade 1 = 1 step up, grey scale 2 = 1 step higher, and so on up to the highest mountain which is white. If you wish to create a good bump/displacement map you need to look at the surface texture and create a map of that. Some of my darker veins aren't raised at all.

If you look at your hand the skin colour information has very little to do with the skin texture, which is why I called greyscaling the colour map a quick and dirty method. As out lined above the bump or displacement maps don't use colour data, they are a greyscale map with the black = none through to white = full, stepped up through the shades of grey information onto the object. So one set of files contains the colour maps and the other contains the texture. If it's silk it will have a fine texture, sacking will be course, regardless of colour. For instance a piece of cloth, may have a plain colour or pattern printed on it, but that is not the texture of the cloth. They can be used as quick and dirty maps to give texture but they may be completely wrong. They don't have any texture information they are in fact colour maps. I think a part of the problem is that the files called 'texture' maps give a false idea.
