Member stuartullman Posted November 12, 2015 Member Report Share Posted November 12, 2015 Sorry if this has been posted before. I know that 3d coat has had issues with UV overlays/borders and I've been ok with them for the most part. Recently our studio updated the 3d coat software, and now I'm getting this every time I paint on the UV borders: http://i.imgur.com/bUD1Nnw.jpg The sphere is mirrored and welded before importing into 3d coat. All I did was paint in the middle of the mesh and this is what I get; pixelish colors with the triangles of the mesh visible. Perhaps it's a setting that I need to check. Any advice would be great. edit: Another thing: If I paint in Texture Editor, the result is very smooth both in the texture editor and the viewport. If I paint in the viewport, it's all pixelish in both views. Quote Link to comment Share on other sites More sharing options...
Member stuartullman Posted November 12, 2015 Author Member Report Share Posted November 12, 2015 One more thing. The bigger the brush, the larger the pixels. Here's me painting with a brush radius of 45: http://i.imgur.com/wbN3gUI.jpg Also, I'm using per pixel scene interface like I always have with 3d coat. using 2048 textures.

Reputable Contributor digman Posted November 12, 2015 Reputable Contributor Report Share Posted November 12, 2015 (edited) Since that is a simple sphere, can you upload it here for others to looks at to see if we get the same problems... What version did you upgrade from and what version are you using now of 3DC... Edited November 12, 2015 by digman 1 Quote Link to comment Share on other sites More sharing options...
Contributor Michaelgdrs Posted November 12, 2015 Contributor Report Share Posted November 12, 2015 This shouldnt be happening , can you please upload the scene? Quote Link to comment Share on other sites More sharing options...
Member stuartullman Posted November 12, 2015 Author Member Report Share Posted November 12, 2015 Here you go. https://www.sendspace.com/file/kn9985 I added a brush stroke just to show what I'm talking about. I'm using 4.5.19 1 Quote Link to comment Share on other sites More sharing options...
Contributor Michaelgdrs Posted November 12, 2015 Contributor Report Share Posted November 12, 2015 I am sorry , i replied by mistake to another thread. Problem is your uvs. Re uv it automatically. Quote Link to comment Share on other sites More sharing options...
Member stuartullman Posted November 12, 2015 Author Member Report Share Posted November 12, 2015 Thanks for the reply I don't think it's the UVs.. I know it was a quick UV setup(the top and bottom of the sphere weren't welded), but try to paint on the UV seam overlap. I'm trying all the models I've worked on before, some of them I've worked on in previous versions of 3d coat and they were fine then, but now they're giving me this same problem. The automatic UV would fix it since it gets rid of the seam. But That's the part that's causing the problem. 1 Quote Link to comment Share on other sites More sharing options...
Contributor Michaelgdrs Posted November 12, 2015 Contributor Report Share Posted November 12, 2015 In general there seems to be an issue other members re ported as well with painting right on or close to seems. My answer was a temporary solution to your problem so you can work Like you correctly said --> The automatic UV would fix it since it gets rid of the seam. But That's the part that's causing the problem. Quote Link to comment Share on other sites More sharing options...

Contributor Michaelgdrs Posted November 12, 2015 Contributor Report Share Posted November 12, 2015 This was reported in Beta thread. Is it the same? And if this is the same , why don't i have this too ? Quote Link to comment Share on other sites More sharing options...
Andrew Shpagin Posted November 12, 2015 Report Share Posted November 12, 2015 In such cases I recommend enabling symmetry. It will solve the problem. Quote Link to comment Share on other sites More sharing options...
Reputable Contributor digman Posted November 12, 2015 Reputable Contributor Report Share Posted November 12, 2015 (edited) In such cases I recommend enabling symmetry. It will solve the problem. It solves the problem on painting almost but does not solve the problem if you apply depth too. If you show the seams in the Paint Room (Shift and the W key) You will see some vertical seams where there are none according to the UV room view. Check the UV room and you can that 3DC does not show any seams there. Hover your mouse cursor over the model in the UV room and look at the uv island preview, it is a tangled mess. Now in the uv-set preview the uv island looks fine. Now use the unwrap function and it it be upwrapped to the tangled mess. I do not know if the problem is exporting from their 3D application or if 3DC is not reading the uv set correctly. I do not have enough information to judge one way or the other. Pictures included to show what I was talking about. Edited November 12, 2015 by digman Quote Link to comment Share on other sites More sharing options...
Member stuartullman Posted November 12, 2015 Author Member Report Share Posted November 12, 2015 (edited) Symmetry doesn't do anything for me, especially considering that it's already painting symmetrically because it's mirrored UVs. We just did a test on a previous version of 3d Coat and none of these problems exist. Painting is smooth. This is only happening in 4.5.19 on seams that share the same overlapped UVs... Also, I tried exporting from 3ds max as obj and fbx with same result. Edited November 12, 2015 by stuartullman Quote Link to comment Share on other sites More sharing options...
Reputable Contributor digman Posted November 12, 2015 Reputable Contributor Report Share Posted November 12, 2015 (edited) So 3DC is seeing the overlapping mirrored uv's but is not understanding it correctly, Possible the welding is causing it but did not in the past? I would send to support a detailed report on your problem, software used etc, steps from a to z and see if Andrew can figure it out. If you are in the middle of a production project. Andrew has in the past been good getting back to users. Let him know you need it quickly resolved because of your current production schedule.

Carlosan Posted November 12, 2015 Report Share Posted November 12, 2015 3DC is seeing the overlapping mirrored uv's but is not understanding it correctly if SYMMETRY is turned off feel free to add a +1 Quote Link to comment Share on other sites More sharing options...
