Advanced Member Metin Seven Posted October 29, 2017 Advanced Member Share Posted October 29, 2017 Hi, Sorry for all my questions, but I'm still exploring 3D Coat, and loving it. I was wondering: If you take a voxel object straight from the Sculpt room to the Paint room, you'll be painting with vertex colors. What's the best / easiest way to convert a sculpted voxel object to an automatically UV-mapped mesh that's ready for UV painting in the Paint room? I assume the key room for this is the Retopo room, but what steps should I take if I want the voxel object to be meshed and get UVs in stead of going through retopology? Many thanks, Metin Quote Link to comment Share on other sites More sharing options...
Carlosan Posted October 30, 2017 Share Posted October 30, 2017 Everything depends on the use for which you are building your model Quote Link to comment Share on other sites More sharing options...
Advanced Member Metin Seven Posted October 30, 2017 Author Advanced Member Share Posted October 30, 2017 Hi @Carlosan, I'm thinking of fairly high-poly sculpts. Triangular polygons are OK, no quad retopo would be necessary. Just spontaneous sculpting in voxels, then quick and easy automatic UV mapping to get it into the Paint room.

Carlosan Posted October 30, 2017 Share Posted October 30, 2017 The Decimate autoRetopo feature is really great as it manages to preserve any sharp edges on your models -access this command pressing RMB over the layer-. Then in Retopo room, use Autoseams to create the uv islands, bake and paint the model directly in Paint Room. Hope this help. Quote Link to comment Share on other sites More sharing options...

Advanced Member Metin Seven Posted October 30, 2017 Author Advanced Member Share Posted October 30, 2017 Hi @Carlosan, I've tried your tips, and I succeeded to a certain extent, assuming you have to press Unwrap after performing the Auto Seams. Then I went to Bake menu ➔ Retopo Per Pixel (No Baking). Finally I went to the Paint room, but things don't work how I expected yet. I can see paint being applied on the texture in the Texture Editor, but I don't see it on my object, only sometimes I see it on the object, and if I apply a text, it looks very jagged and doesn't show up in the Texture Editor, as if vertex colors are used in stead of the texture. Thanks, Metin Quote Link to comment Share on other sites More sharing options...
Advanced Member Metin Seven Posted October 30, 2017 Author Advanced Member Share Posted October 30, 2017 Hmm… I just discovered that the text was applied to the texture, but the 3D model still looks like it's showing vertex paint, or a very low resolution proxy of the actual texture?

Carlosan Posted October 30, 2017 Share Posted October 30, 2017 Is show voxels in paint room off ? Quote Link to comment Share on other sites More sharing options...
Advanced Member Metin Seven Posted October 30, 2017 Author Advanced Member Share Posted October 30, 2017 Thanks, @Carlosan, that worked. I'm almost there now. There's just one more issue: certain parts of the UV map don't receive paint. See the attached screenshot. Quote Link to comment Share on other sites More sharing options...
Advanced Member Metin Seven Posted October 30, 2017 Author Advanced Member Share Posted October 30, 2017 (edited) Hmm, it's even weirder — as I orbit around the model, the visible paint flips to the other UV parts. Might this be a bug of the 4.8.3 beta for Mac OS that I'm using? Otherwise I could try to revert to the default Mac OS driver for my NVidia graphics card. I'm currently using NVidia's latest Web driver. Edited October 30, 2017 by Metin Seven Quote Link to comment Share on other sites More sharing options...
Carlosan Posted October 30, 2017 Share Posted October 30, 2017 Try testing the workflow in a new fresh scene without surface paint any model before. Quote Link to comment Share on other sites More sharing options...

Just a hunch but I've seen similar behavior in 3D Coat when there are multiple copies of the same paint object (since they both occupy the same space sometimes the unpainted version will render over the top of the painted one and vice versa, this usually results in the object flickering and the texture appearing and disappearing on different parts of the model as you move the camera). Check your Paint Objects palette and make sure you don't have multiple copies of the object visible. Quote Link to comment Share on other sites More sharing options...
Advanced Member Metin Seven Posted October 30, 2017 Author Advanced Member Share Posted October 30, 2017 Hi guys, Many thanks, I'll try your suggestions tomorrow (CET). My system is currently bogged down because of a heavy high-res rendering. Quote Link to comment Share on other sites More sharing options...
Advanced Member Metin Seven Posted October 31, 2017 Author Advanced Member Share Posted October 31, 2017 Hi @Carlosan and @Fluffy, I've tried it again today, and it worked (see my attached artistic masterpiece). Thanks a lot! I checked if there were multiple objects in the Paint Objects, and there was only one, but I guess the problem was that I had already painted on the model using vertex colors, before switching off Show Voxels In Paint Room. Have a nice evening, Metin 1 Quote Link to comment Share on other sites More sharing options...
