Hi, I was wondering if anyone could shed any light on how to create a specualr map from a Zbrush model. I have been using XNormal to create my normal/occulsion maps but I am unsure how to create a good specular map. Any help at all would be greatly appreciated. Thanks in advance! :)
Hi, maybe I should rephrase... I have created a character in zbrush and have exported the high res model as an obj. I have then used xnormal to create my maps from that. I was really wondering if you can create specular maps in xnormal? I have seen a tutorial on how to create a specular map from a bump map in photoshop,…
Creating your own specular maps is a much better practice. I would render an ambient occlusion map in xNormal and overlay my UV layout on that in Photoshop/GIMP/whatever, then paint my specular map on a new layer(s). You can blend in the ambient occlusion map where needed too that way. Good luck.
Hello Simon-s, When creating specular maps for game characters, remember that you should have lower specularity on the recessed areas of the model. Although this is not technically correct, it helps to sell the normal map more convincingly, as 'shiny' recesses can break the effect you are trying to achieve. I therefore…
