random thing: I have been working on my 3dcoat/blender voxel-mesh to subdivision workflow using poly painting similar to zbrush's "poly group it" where you paint topology corners as black lines and then that turns into mesh patches, which then feed the remesher.    I feel close to having the freedom of being able to work with voxels but being able to wind up with usable sub-d results without full retopo. Hopefully if I get it working it can serve as an example for some 3dcoat workflow UX! still scaffolding the blender side and 3dcoat side scripting to make it not 200 steps raw voxels Painted corners using curvature masking / handpaint cleanup in surface mode using blender script I wrote to turn the edge vcols -> clean face group patches clean creased sub-d quad mesh You can get even better results than this with a bit of face group grooming. But yeah once it's sub-d I can actually use it as a source for reduction / adding additional subdivision detail modelling to.  it even seems pretty robust to imperfect / slightly round corners you get out of voxel sculpting! I will probably release the blender / 3dcoat scripts sometime soon. The important part is that you have to refine / manage the face groups, smooth their intersections and try to straighten-ify them as much as possible, or the quad remeshing algorithm gets confused. however blender's face sets has a lot of this functionality baked in, so what you can't do in 3dCoat, you can just do in blender. I think the painted face set boundaries result is the best of both worlds, you can do most of your sculpting / prep work in 3dcoat and then kick it into blender for meshing.

Let me check the scale correspondence you can use    To select the scale changes.

Paint room exports models exactly the same(scale, topology, orientation).  Somehow exporting from sculpt room doesn't give me the same results.  I did just find out we can skip decimation in sculpt room so topo doesn't change.

Please share the model to take a look Yes, some are tiled and some are not, it is not possible to separate materials by tile categories.   It is better to select triangulate at export, ensuring consistent shading, preventing texture distortion, and guaranteeing the model renders identically across different software or game engines. It locks the geometry, avoiding unpredictable auto-triangulation because every game engine triangulate the mesh at import.  So if you created your painting in quads and the game engine triangulates, some vectors of the normals in the normal map might be distorted. But remember that the texture is projected onto the UV layout distribution. Using tiled textures makes no difference if the faces distribution in the UV unwrap is distorted.

It is a texture that has no repeating simple pattern, it is not symmetrical in both X and Y , so you are right, my texture is tiled.  Question 1: I tried with some 3Dcoat smart materials, is it right that some are tiled and some not? If so, does 3Dcoat have an easy way to separate the tiled 3Dcoat materials from the non-tiled ones? Question 2: Importing a 3D mesh with 3Dcoat setting "Triangulate" enabled, when is it smart to use triangulate? I ask because of the community post below. Or always use triangulate ? :   

What is the texture resolution ?

Paint Room export models with UVs applied and textures baked/painted into 2D images, why do you need to export from Paint room. That's it is not clear to me. There is an old thread asking for that workflow, is this what do you need to perform ? Painting Vertex Colors onto regular UV mapped, per pixel painted meshes (e.g. mapped onto Trim Sheets, Atlases etc.) is a very common age old technique in Game Art. For instance, before texture memory was as affordable as today, color variation or visual breakup like dirt and grime could be stored in Vertex Colors directly at authoring time in an external application.. ------------------------------------- Currently 3DCoat only support this export way: High poly mesh = export from Sculpt Room Low poly mesh = export from Paint Room Mid poly mesh = Paint Room at MVP baking model

I'm trying to paint smaller objects like teeth but I can't fix the edges of these UVs either in the 3d viewport or the texture editor. I've tried resizing the UV island larger for more resolution, I have tried keeping the islands separate but that doesn't seem to help. Is there anyway I can fix this, since I have to paint a lot of teeth and mouth parts and this is really ugly looking. I've unwrapped it again just to make sure and scaled it to size but nothing seems to help. Anyone found a good solution to this?

Is that from Paint room export or Sculpt room export? When I export from Paint room I don't see vertex color in blender. Even the default sphere in 3dcoat I export it from Paint room and import to Blender and there's not attribute. From Sculpt room it works as usual and I see vertex color. But I need it from Paint room. 

Are you applying a tiled texture ?

Was trying to do simple things as starters. To big projects usually fail at certain points and redoing the whole thing that costs days to create is just a waste of time. Blender Created a cylinder 32 vertices with end and begin face, so it is closed. shade smooth, mark sharp at both edges Import for "per pixel painting" At import 3Dcoat >> enable option "Triangulate"   Tried creating an UV map in Blender and let 3DCoat create one by selecting "auto mapping" But both times I have 1 visible straight line when I try to apply any material in 3Dcoat. It is a smart material I am trying to create in 3Dcoat, just added color, metal, height, roughness.   I just cannot get that straight line to go away. What am I doing wrong?  

Hi Sheeplion, thank you for the suggestion and the link of the game, which I've just wishlisted.  

.fbx import with will be visible using vertex colors node in Blender. It is under "Color Attributes"  Sticking vertex colors at the back of coordinate vectors is not specified by the .obj format, and Blender’s .obj import/export doesn’t support this   or after import .ply try this other settings

Blender doesn't read .ply correctly from 3dcoat. I tried fbx from 3dc and still blender doesn't read the vertex colors.  From nomad sculpt I can export an obj file with vertex color and import to blender and blender reads it.  Does 3dc have a way to embedd vertex colors on obj files?

Thanks. Is the mesh in the sculpt room exactly the same as the imported scanned mesh? We can skip decimation on export to keep the mesh exactly the same as the original scanned mesh? I did this a few times before without the applink and I had scaling issues and had to decimate on export when I exported the mesh from sculpt room. Topology changed of course which is not wanted. But the vertex color was there indeed.  So what I'm doing now is importing in paint room to paint on uvmaps and export texture maps and bake those into vertex color in blender. But it would be great if I could export vertex colors directly from the paint room because the paint room doesn't alter the scale or topo of meshes. 

On windows you have the program Materialize by company Bounding box software. http://www.boundingboxsoftware.com/index.html They are also the creators of the game. I found this while trying to find company info. Never knew. Going to support them for this nice Materialize tool. https://www.gog.com/en/game/prodeus

The primary difference between a UV-textured mesh and a polypaint (vertex color) mesh lies in how the color data is stored and displayed:  - Vertex color stores color directly on the vertices of a 3D model, ensure you have a high-polygon model. - While UV texturing maps a 2D image file onto the mesh using UV coordinates. 3DCoat will automatically recognize and map these to vertex color data upon import, File > Import or you can bake them directly in the Paint Room. After that go to => File > Export selected Object > .ply
