Member Ambershore Posted December 12, 2018 Member Report Share Posted December 12, 2018 Greetings, I have an issue when calculating curvature, it shows artifacts on the default 3Dcoat tiling plane (new scene, Paint UV mapped mesh). These artifacts seem related to the tiling planes polygons (3Dcoat's default object, or imported one, same issue). https://imgur.com/UZJESMM https://imgur.com/dLARzKS Any suggestions?

Carlosan Posted December 12, 2018 Report Share Posted December 12, 2018 Hello Using latest version 4.8.28A i cant replicate this issue, sorry. Edit > Preferences > General Switch Realtime padding to interpolated, it will help. Quote Link to comment Share on other sites More sharing options...
Member Ambershore Posted December 12, 2018 Author Member Report Share Posted December 12, 2018 tested on the same version too. I tried interpolated color, and each of the other kind of padding, same issue, halas. It's visible, of course, only when making the curvature map visible (only to check), but of wcourse it makes the smart materials, or any concave/convex condition painting practically unusable. I even uninstalled, deleted all prefs / documents folders, reinstalled with defaults. the same. Quote Link to comment Share on other sites More sharing options...
Carlosan Posted December 12, 2018 Report Share Posted December 12, 2018 Sorry but still cant replicate. Please send support-related questions to Andrew Shpagin at support@3dcoat.com Thx Quote Link to comment Share on other sites More sharing options...
Advanced Member Vexod14 Posted December 13, 2018 Advanced Member Report Share Posted December 13, 2018 (edited) @Carlosan Please look closer at your curvature, its bake is wrong in many ways, all artifacts explained by @Ambershore are aligned on geometry's edges. Clearly viewable on his bake as long as he may have used the new curvature bake system (where you can add a long range curvature, which is as issued as AO bake when it comes to bake overlapped UV islands). Look closer to all your geometry's edges, here are all the annoying artifacts. And I've spotted this exact same issue dozens of time but got 0 response nor fixes. And the issue is NOT only viewable on the basic tileplane, in fact, you just need to have overlapped UVs. More overlapped islands leads to even more issues, darker curvature ( instead of a 50% grey on planar surfaces), and also "triangle" artifacts over the whole overlapped areas. I attached a file of your screen where I spotted parts that baked the wrong way in red. Look closer at them, and no need to tell you that a fix would be more than welcome. Here are all images I've posted long time ago, and the issue is still here, baking 0 pixel on these edges... 3DCoat_Issue.tga Edited December 13, 2018 by Vexod14 2 Quote Link to comment Share on other sites More sharing options...
Carlosan Posted December 13, 2018 Report Share Posted December 13, 2018 Thx for your reply, very useful - we got a reply * Dev team is working on this issue. 1 Quote Link to comment Share on other sites More sharing options...
Advanced Member Vexod14 Posted December 14, 2018 Advanced Member Report Share Posted December 14, 2018 Ow ♥ if this issue get fixed, 3DCoat could be even more the software of my dreams (it is already, I guess you know that ^^"). But being able to create tileable stuff without this overlapp issue could be so awesome, and will enable users to do all process inside 3DCoat. I'm so hyped ! More than Xmas ^^ Quote Link to comment Share on other sites More sharing options...
Member toomanydemons Posted January 27, 2019 Member Report Share Posted January 27, 2019 lol I just ran into this a little while ago and sent the file to the support team. I guess they already knew about it. Now I know it's the curvature map. I guess for the time being I'll just generate it in other software. Cheers! ^^ Quote Link to comment Share on other sites More sharing options...
Advanced Member Vexod14 Posted April 19, 2019 Advanced Member Report Share Posted April 19, 2019 It's not only the curvature but I guess the baker itself, AO is bad too and at the exact same places =/ Quote Link to comment Share on other sites More sharing options...
Carlosan Posted April 20, 2019 Report Share Posted April 20, 2019 Dev team have reported some improvements on this issue, but it was not enough. 16.04.2019 4.8.38 - Fixed problems related to tiling and filling layer with material. - Fixed a lot of errors related to curve modifiers and instancing volumes, loading/saving scenes with instances and modifiers. - Fixed "To uniform + Undo" problem. - Fixed problem of mesh exploding during extrude faces in retopo room. 1 Quote Link to comment Share on other sites More sharing options...
Advanced Member Vexod14 Posted August 25, 2020 Advanced Member Report Share Posted August 25, 2020 Hi Carlosan ! I've been back on overlapped texture stuff aaaaaaaaand...the issue is partly gone (but just for curvature) - AO still breaks over the same edge random patterns near seams - Curvature works fine only if nothing else than the simplest curvature mode (smooth mode fails, long range fails) Hope this gives some clues to debug this 1 Quote Link to comment Share on other sites More sharing options...
Advanced Member pickers Posted August 26, 2020 Advanced Member Report Share Posted August 26, 2020 Have you tried the new symmetry translation? It has the same tiling function. Just to set to surface mode when using that due to performance. Quote Link to comment Share on other sites More sharing options...
Advanced Member Vexod14 Posted August 27, 2020 Advanced Member Report Share Posted August 27, 2020 @Picker I'm using it over lowpoly meshes (not on sculpt/voxels. I saw that's possible and interesting at some point, but this doesn't fit my needs which are focused on the paint room ;)) Quote Link to comment Share on other sites More sharing options...
