Member hoihoi3 Posted October 6, 2018 Member Report Share Posted October 6, 2018 When I adjust UV,another UV set can be select and move. This problem only occurs when select Vertices, Edges, Tweak. I use version 4.8.20 Quote Link to comment Share on other sites More sharing options...
Carlosan Posted October 6, 2018 Report Share Posted October 6, 2018 Hello do you have multiple UVsets ? Please check this serie - Sidenote: 3DC has no true internal UDIM tiling creation like Maya or similar applications. You can import UDIM as tiles " Import Tiles as uv sets" 3DC will create a UV set for each tile. When exporting choose, " Export UV sets as Tiles" and they will be put back in a tiling order. Hope that help Quote Link to comment Share on other sites More sharing options...
Member hoihoi3 Posted October 7, 2018 Author Member Report Share Posted October 7, 2018 I didn't know multiple UV map and UDIM. When export from Blend er,objects had only one UV map. Quote Link to comment Share on other sites More sharing options...
Carlosan Posted October 7, 2018 Report Share Posted October 7, 2018 Your map needs to fit on a single tile ? UDIM is a much easier way to UV map, as it lets you visually separate your UV groups or materials over several tiles. But saddly Blender dont support uDims. In the images that you added there are two uvmaps sharing the same uvspace. Try modifying islands seams a little and unwrap it again.

Member hoihoi3 Posted October 7, 2018 Author Member Report Share Posted October 7, 2018 Probably I understood. I placed UVs in the same tile in multiple UV maps but UV island must be in a different position across multiple uv maps, is not it? However, this problem seems to happen even when creating a new uv set in 3dcoat, how can I avoid it? I didn't use UDIM simply because I didn't know it,so I will study. Thank you.

Carlosan Posted October 7, 2018 Report Share Posted October 7, 2018 Just to know your workflow. Are you importing for painting, or only for bake... How do you export it ? Is only one model with separated mesh ? Or are several models ? Can you share your import settings please ? Quote Link to comment Share on other sites More sharing options...
Member hoihoi3 Posted October 8, 2018 Author Member Report Share Posted October 8, 2018 It is important to paint. The model contains multiple objects and materials. Export and Import option are as show in the image. Quote Link to comment Share on other sites More sharing options...
Carlosan Posted October 8, 2018 Report Share Posted October 8, 2018 Thee is a Blender Applink to come in out from Blender. But please check the uvsets, are you working on the right one ? Quote Link to comment Share on other sites More sharing options...
Member hoihoi3 Posted October 8, 2018 Author Member Report Share Posted October 8, 2018 Thank you for introduce. However I dont want to use it because windows move every time I use applink. I tried it just in case but the problem occurred. I suppose the UV set works correctly. Quote Link to comment Share on other sites More sharing options...
