Advanced Member kirkl Posted January 13, 2011 Advanced Member Report Share Posted January 13, 2011 I am doing my every texture now with a help of Surface noise in Zbrush. This feature is fantastic. I recall I saw something that was looking similar in one of 3dcoat videos some time ago. Is it so and still there? Quote Link to comment Share on other sites More sharing options...
Psmith Posted January 13, 2011 Report Share Posted January 13, 2011 Kirkl: The only thing that is really similar to this function, in 3D-Coat, is the use of "Shaders" as they are found in the Voxel Room. Zbrush's noise is procedurally based and so are some of the Shaders in 3D-Coat. But, they are only good for internal rendering within 3D-Coat, itself. You can apply 3D-Coat Materials in what appears to be a "noise" fashion - and this is quite fast - but it is manually applied and depends upon your own skill to make it convincing. Materials can contain Color, Displacement and Specular information - speeding manual painting application. I actually prefer the manual method, since it makes it much easier to overcome that "computer generated" appearance - so typically seen with many procedural 3D renderings.

I constructed my own shaders, I gave them a bump value. When baking in MV or PPP these bumps can be captured as normal maps. Before baking its good to have ambient and contrast at the lower value. The normal map captures the bump noise automatically. The funny is that I use a similar method in zbrush. I import the bumpy 3dc UV texture map to zbrush, convert it to alpha and have some interesting displacements, better than the surface zb noise.

philnolan3d Posted January 14, 2011 Report Share Posted January 14, 2011 Well I'll be... It does work, I never tried reducing the lights before baking. Quote Link to comment Share on other sites More sharing options...
Applink Developer haikalle Posted January 14, 2011 Applink Developer Report Share Posted January 14, 2011 One way doing this is to use fill tool's modulation type. Using these with zreeze tool you can get very interesting results. here is brief video. Also good tip is to create two diffrent kinds of noise in two separate layers. Then playing with "depth blending mode" and you get some interesting noise patterns. But I have to admit that zbrush surface noise is very nice tool because you can control the noise pattern with the curve. Quote Link to comment Share on other sites More sharing options...
Advanced Member kirkl Posted January 14, 2011 Author Advanced Member Report Share Posted January 14, 2011 Thanks for the tips. That fill modulation is what I saw I think . It's pity it don't work in voxel mode too. michalis. Could you tell a bit more please about baking shaders to MV. It seems to only bake the color information on my end. Not sure where I should decrease the ambient and contrast. Quote Link to comment Share on other sites More sharing options...
Applink Developer haikalle Posted January 14, 2011 Applink Developer Report Share Posted January 14, 2011 I agree. We need some kind of noise tool in the voxels. Quote Link to comment Share on other sites More sharing options...
Advanced Member Digital777 Posted January 15, 2011 Advanced Member Report Share Posted January 15, 2011 Cool thanks for the tips, very useful Procedurally based surface noises would be very useful voxels tools. Procedural/Interactive weather effects would also be very cool, i had a few quick ideas a while back - http://www.3d-coat.com/forum/index.php?showtopic=4306&st=0&p=33438entry33438 Quote Link to comment Share on other sites More sharing options...
