Texture/ material question

[alienhive]

Forgive me if this has been covered, but can I, using texture master, pick a material complete with bump mapping, and paint with it, like with Deep paint 3d?
Or would I be better off painting colours onto model, then adding bump map with deep paint?

You know... I have wondered the same thing since I first started using Zbrush. I'm pretty sure that Zbrush does not include separate channels for bump, transparency, glow and specular maps. This would be an excellent feature though!
My suggestion would be to make the texture map in Z... possibly make your other maps using only grayscales. Put them all together in your raytracer of choice.
Alternately, you could use an alpha mask of your bump map on your object and then inflate it.
If you have enough polys this will probably work... If you want low polys scrap this idea.
Or just use DP3d for your other maps.
I'm sure Aurick will elaborate, or let us know the possibilities!
Take care,
Michael

Thanx for your advice. I think I will do my bump maps with DP3D, unless anyone else can give me any other help???

The typical approach with ZBrush is to paint your model with a nice Color Bump value in the material. Then the trick comes in getting that bump into the form of a bump map.

After texturing, clear your screen and size your document to match the texture size. Now, using that same material, fill the layer with the texture. You'll see it with all of its bumps. Use the MRGBZGrabber tool with Auto Crop off and Shaded RGB on to capture the canvas. Shaded RGB captures shading caused by the material channel (such as Color Bump) to be converted to RGB color. Now you'll have a second texture in the Texture Palette. Click the Make Alpha button, go to the Alpha palette, and export a really great bump map!
