Zbrush 3 and RS
Hi! Does anyone use Zbrush and RS? I cannot export OBJ objects properly with UV-textures. I can export displacement mapping and OBJ-object, but when I try map disp. map in Realsoft mapping is aligned wrong. Is there any tutorials for exporting models and disp.map into RS? Ville
Re: Zbrush 3 and RS
In the material's property window, try flipping the y for the texture. RS typically considers this differently than everyone else.. cm From: Ville Tirronen [EMAIL PROTECTED] Date: 2007/07/30 Mon AM 10:24:42 CDT To: user-list@light.realsoft3d.com Subject: Zbrush 3 and RS Hi!

Re: Zbrush 3 and RS
Hi Ville, Maybe you have to turn the textures upside down. I always have to do this when I import OBJ created with BodyPaint. Or I flip the UV's. Arjo. Ville Tirronen wrote: Hi!

Re: Zbrush 3 and RS
Hi Ville, I would be very interested to understand how to do what you described. When you figure it out, maybe you could put together a tiny tutorial on it? That would be great, but no problem if not.. Great day everyone, Daniel On 7/30/07, Ville Tirronen [EMAIL PROTECTED] wrote: Hi! Does anyone use Zbrush and RS?

Re: Zbrush 3 and RS
Hi Ville, I recently was experimenting with something similar between RS -- Blender and back. Blender also has sculpt tools similar to ZBrush. I was attempting to export an OBJ, into Blender and Sculpt, create a Normal Map of the Sculpted mesh from a Low and High rez mesh inside XNORMAL [ www.xnormal.net ]. Then apply this Mormal map to the lo-rez mesh in RS From what I gather RS has difficulty with large poly meshes, the type required for sculpting. So - to get over this one might try NORMAL MAPS [ another phrase to look at is tangent space ]. Here is some mails I got from VESA re same: Regarding normal mapping: there are no big secrets involved, you simply assign a texture map to the surface normal. If the normal map comes from another application, one probably has to shift pixel values around zero: surface properties bump normal = texture(map coords) // Assign the normal map bump normal -= constant (0.5, 0.5, 0.5) // shift from 0 .. 1 to -0.5 .. +0.5 In the last VSL object, VSL editor / General tab / Normalize option should be set so that the surface normal gets again unit length. === AND ALSO THIS: Thanks to Timo for this observation at the IRC: == timo2 or more like you have to change the normal information _from_ tangent space to world space before you assign it timo2 and you need uv-coords for it to work So their now, you have been told :) Any wisdom on that? Yes, there is :) My brief example was indeed for a fixed space normal map, not for tangent space mapping. I'll consider this - maybe a new VSL operation 'map to normal space' is required. Of course, U and V directions are not available for all object types (analytics, metaballs etc), but that's really not a problem because normal mapping is mostly related to polygonal or SDS objects. = REGARDING A MESH I SENT VESA WHEN ATTEMPTING NORMAL MAPPING to RS: == Thanks! I tried it and found already the first obstacle. .obj import reads the required UV data as a 'face material' , which is not suitable for bump mapping. Interpolation is so discontinuous that face boundaries show up - I guess that was the rpoblem in the test image you sent me. I manually created a UV set and assigned the height map using it. The result was then OK. So, either .obj import needs the UV set option, or we have to create a simple tool, which converts a face material to a uv set. We will add it as soon as possible (probably into the first SP release for v6 - we will not delay the actual V6 release any more because of new development).

r3metame.js missing (Re: Script to make curve.)
Hi all, I finally tried the script and got some errors. I think it's caused (on my machine) by a missing include file 3d/r3metame.js... another include file raytr/r3cmetnu.js tries to load it (which is in turn loaded by r3subdiv.js), resulting in an avalanche of errors... Apparently, the whole '3d' directory is missing in V5 SP4, so maybe there's nothing wrong with the curve_gen script? The error should occur any time r3subdiv.js is loaded. Hats off to your complicated script K-UDA, I hope we'll get it working! hope this helps, Mark H At 15:55 28-7-2007, you wrote: Hi K-UDA.. Thx for your help n the file... Sorry to say that it didnt help either.. =( Must be something in the RS files.. or some bug Maybe I have some rests from some of the betas... I might need a complete reinstall of V5... =) Again.. thx for all your efforts.. and also thx for sharing your cool script which I hope I can test out some day..
