Hey I came up with the idea how cool it would be to paint your specular maps directly in the viewport with realtime lightin in max using a special shader. From this starting point I thought, why not painting bumpmaps and normalmaps too in relatime on the mesh? While this is just an idea, I am curious if this could be made…
Well, it is not really limited to max (though, it would be cool not use 3rd party programs all the time, especially if we talk about the gui nazis at pixelogic) However, the main idea is NOT limited to diffuse textures. I am perticulary speklaing of normalmaps and specmaps. Why building up a highpoly character if you could…
Here's a freebie 3D painter plugin for max. http://www.max3dstuff.com/max5/3dPainterPrototype/help.html Very basic, but works. Only one map at a time. However I guess you'd need to use an FX shader to see the results affecting specular or bump. Don't know if that'd work either. I think Body Paint 3D has a painting mode…
You can use a 3d paint tool such as deeppaint or body paint which allows painting channesl in real time shaded mode. Also zbrush I think? Also if you're using max you may wan to check out ghost painter, seems like an awesome idea although I don't use max, brings photoshop window in to the max viewport.
