New Member stevej Posted May 21, 2014 New Member Report Share Posted May 21, 2014 Hi all. I'm looking for a tool/process to convert normal or displacement maps back into to a mesh. I ran across the following article regarding the process using ZBrush. I was wondering if a similar process is possible in 3D-Coat (as it would save me quite a few dollars). http://www.surlybird.com/tutorials/textogeometry/index.html Quote Link to comment Share on other sites More sharing options...
Javis Posted May 21, 2014 Report Share Posted May 21, 2014 Hi! Unless Andrew has added a new feature, I'm pretty sure this is not possible. I think it would make a really good feature for 3DC. =) I'll put this up on Mantis. Quote Link to comment Share on other sites More sharing options...

I thought there might even be something standalone, but it doesn't look like it. I'm hoping to use the process to just create simple geometry to sit underneath decal textures in games.

Advanced Member polyxo Posted May 21, 2014 Advanced Member Report Share Posted May 21, 2014 (edited) I can't quite follow. Most mesh modellers allow you to apply a displacement map to a subdivided mesh and to actually bake the displacement into, also free ones like Blender (here one would just use a Displace Modifier and load the image). It's actually a very straightforward process, also in Zbrush (the tutorial you refer to is made for a version of Zbrush which is about 10 years old!). One can do so with a tiling map and a plane or on arbitrarily complex object but matching UV's are required for the latter. In 3DCoat one of the possible processes was File / Import / ImagePlane. You could deform more complex objects with UV's by importing to the Paint workspace and importing a matching Displacement map through Textures / Import / Displacement Map. Afterwards the result can be exported out as a HiPoly mesh. If you are looking for a specialized tool for just this purpose there's quite a few options, including Artcam or RhinoEmboss (a plugin for Rhino).

Reputable Contributor digman Posted May 21, 2014 Reputable Contributor Report Share Posted May 21, 2014 (edited) Your title is somewhat confusing. "Texture to Mesh" Are you just looking to create a normal map which only needs a single plane to create the illusion of depth. Of course more polygons can be use. A displacement map needs a large amount of quad polygons to displace the polygons from the greyscale height image. The article covers creating depth details in the above fashion. 3DC has no problems creating depth details like the article... There a few ways to go about it...

Javis Posted May 21, 2014 Report Share Posted May 21, 2014 What the OP is talking about, is importing a map (normal or displacement), applying it to a mesh, then exporting that displaced mesh out with all of the details as actual geometry. Modo can do this by freezing the displaced mesh. Quote Link to comment Share on other sites More sharing options...
Reputable Contributor digman Posted May 21, 2014 Reputable Contributor Report Share Posted May 21, 2014 (edited) Javis, got a question... 3DC can export a high polygon mesh from a height map using MV mode. It sounds though that you are saying that you create a true low polygon mesh based off the height map by freezing the displaced mesh in Modo. Is this assumption correct?

Reputable Contributor AbnRanger Posted May 21, 2014 Reputable Contributor Report Share Posted May 21, 2014 Hi all. I'm looking for a tool/process to convert normal or displacement maps back into to a mesh. I ran across the following article regarding the process using ZBrush. I was wondering if a similar process is possible in 3D-Coat (as it would save me quite a few dollars). http://www.surlybird.com/tutorials/textogeometry/index.html If you have a base mesh, and want to use a displacement map to deform the object, then export the displaced mesh, that is totally doable in 3D Coat. FILE > IMPORT > Microvertex Painting TEXTURES > IMPORT > Displacement Map FILE > EXPORT > Hi-Poly mesh (try the first option before the others, because it will likely be dense enough and the others could bog your system down) This video shows this process...in order to take image map sculpting done in the Paint Room, into the Voxel Room....so you can carry all that work into the Voxel Room to use the advanced tools there, if you prefer.

New Member stevej Posted May 21, 2014 Author New Member Report Share Posted May 21, 2014 Thanks for all the tips guys - I'll try everything out. @Javis - it's interesting that you mention modo as that's my current modelling package. I've been discussing this same topic on their forum and have a couple of things to try there too. Quote Link to comment Share on other sites More sharing options...

It sounds though that you are saying that you create a true low polygon mesh based off the height map by freezing the displaced mesh in Modo. Is this assumption correct? Hey man! I haven't used MV mode in a while, so I'm not really sure how that room functions these days. Basically you have your low poly mesh and an existing texture map that displaces the surface. If you see the results in the render window or preview in Modo, you can freeze the mesh you see, exactly as it is in the render or preview. It wont be a low poly mesh, but rather a pretty high poly one. Quote Link to comment Share on other sites More sharing options...

If I remember right, to freeze displacement it's under Geometry>Freeze, which brings up a prompt. There should be a tick box there for freezing displacements, deformations, etc..
