Member SeekerOfWisdom Posted November 3, 2015 Member Report Share Posted November 3, 2015 When painting on a smaller scale, there does not appear to be smooth painting going over my seams. They are getting in the way and its like impossible to paint over them. Notice the visible seam in the following pic when trying to paint over it: Also why is the quality so jagged? The same happens to my textures even when using 4k maps, also I set the project UV set to 4k too. Using per pixel painting on a low poly mesh, tried different uv's and brushes, texture size is 4k and looks perfect in photoshop Quote Link to comment Share on other sites More sharing options...
Carlosan Posted November 3, 2015 Report Share Posted November 3, 2015 Hi ! Are you using the version 4.5.20 ? Quote Link to comment Share on other sites More sharing options...
Member SeekerOfWisdom Posted November 3, 2015 Author Member Report Share Posted November 3, 2015 Hi ! Are you using the version 4.5.20 ? I am using the 4.5.16 trial (Planning on buying full version if I can get this worked out!) This stuff shouldn't be happening right? Should I try to download 4.5.20 somehow? Thanks!

Member SeekerOfWisdom Posted November 3, 2015 Author Member Report Share Posted November 3, 2015 The issue still seems to be there, both seam turning blackish and different colors when painting over, and the jaggedness. Using 4.5.20 Quote Link to comment Share on other sites More sharing options...
Carlosan Posted November 3, 2015 Report Share Posted November 3, 2015 Could you share the model ? Quote Link to comment Share on other sites More sharing options...
Member SeekerOfWisdom Posted November 3, 2015 Author Member Report Share Posted November 3, 2015 Sure its just a simple pants model I retopo'd, tried making different types of uv's in 3d coat and both maya, issue still persists. Something odd though is when painting in mudbox it paints over the seam smoothly, and displays fine in maya, BUTinside unreal engine the seam becomes visible with the same display problem as 3dcoat. So I guess 3dc is more true to what unreal is, Either way what could be the problem? Are my uv's not proper even though I tried many different ways? Here is the model - https://www.dropbox.com/s/kqk96vo6uuxzikz/pants1.obj?dl=0 Quote Link to comment Share on other sites More sharing options...
Reputable Contributor digman Posted November 3, 2015 Reputable Contributor Report Share Posted November 3, 2015 I will check the model out but it might be tomorrow before I can get back here to post... Thanks for uploading the model... Quote Link to comment Share on other sites More sharing options...
PolyHertz Posted November 3, 2015 Report Share Posted November 3, 2015 (edited) It's an accuracy issue with the padding algorithm 3DC uses thats been around for a very long time. It can easily be seen on any of the default meshes by painting a thin strip of paint over a seam with texture filtering turned off.

Carlosan Posted November 4, 2015 Report Share Posted November 4, 2015 I can reply the same result pushing the zoom in to the display limit My preferences padding is 64 Quote Link to comment Share on other sites More sharing options...
Member SeekerOfWisdom Posted November 4, 2015 Author Member Report Share Posted November 4, 2015 (edited) Thanks for taking a look! A few questions- Where can I find this padding preferences? What about the jaggedness of the lines and how pixelated they look when painting that small, is this normal? Or does it rely on the mesh topology / resolution? And a question about uv seams in general- Is it not really possible to completely hide a seam? Painting over it will still be a bit notice-able in a game engine like unreal if you look close to the texture? So even with this method, the only other way to go about it still is to place the seam cuts in hidden places? As someone new to understanding UV's, this seems hard to do sometimes when you want to avoid stretching I've started to examine game models and although some games have seams easily spotted everywhere, others I can sometimes not even find any seams!Even on unclothed characters- Not on the inner leg, outer leg, inner arm, outer arm, back neck no where! How are they doing it? Thanks very much for the help! Edited November 4, 2015 by SeekerOfWisdom Quote Link to comment Share on other sites More sharing options...

Andrew Shpagin Posted November 4, 2015 Report Share Posted November 4, 2015 Ok, thaknks for reporting! Reproduced and fixed, wait for 4.5.21, fix will be included there. 4 Quote Link to comment Share on other sites More sharing options...
Member GregP Posted November 15, 2015 Member Report Share Posted November 15, 2015 I still seem to have this problem in 4.5.22. I placed a dot right on the symmetry line and unless I use symmetry I get an artefact even though the UV's are mirrored. Is there a setting / something I'm missing. Cheers Greg Quote Link to comment Share on other sites More sharing options...

Cheers Greg From my testing it appears to be a mirroring UV island bug... Like you I get artifacts unless I have symmetry enabled... Baked from the retopo using using PPP without a normal map... This is a different problem than the original post... Edited November 15, 2015 by digman Quote Link to comment Share on other sites More sharing options...
Member GregP Posted November 15, 2015 Member Report Share Posted November 15, 2015 Ooo the plot thickens, is there a bug report for this already? Cheers Greg Quote Link to comment Share on other sites More sharing options...
Reputable Contributor digman Posted November 15, 2015 Reputable Contributor Report Share Posted November 15, 2015 Not sure about a bug report... I do not have time to make detail bug reports but I did post in the beta thread and uploaded a simple 3DC file for others to test... Quote Link to comment Share on other sites More sharing options...
Carlosan Posted November 15, 2015 Report Share Posted November 15, 2015 3DC is seeing the overlapping mirrored uv's but is not understanding it correctly if SYMMETRY is turned off Quote Link to comment Share on other sites More sharing options...
Member GregP Posted November 15, 2015 Member Report Share Posted November 15, 2015 Thanks Carlosan :-D hope it's an easy fix for the team it's pretty annoying. Quote Link to comment Share on other sites More sharing options...
