Hello. I'm looking for help. So here is my low-poly mesh, and it looks fine in 3d-coat. (pic 1) But if we take a look at it's normal maps (pic 2), we see it's being split at UV-Island edges. If I understand correctly those edges should not be there and they seem to cause wrong look in 3ds max or another software. The question is: am I missing something? Why does 3d coat break normal map on those edges? How do I bake it right? Tried switching GL and DX versions - to no avail. Tried different baking presets (for 3ds max, for Unity etc) - all the same. (There is another thread on this forum where a guy had similar issue, but that solution did not work for me (He had to update 3d coat and switch GL to DX)) Thanks in advance! -
So I have a question, I was trying to do this in Blender, but then I find out 3DCoat and decided to give it a try to see if it would make this any easier. The idea is that I have a model with some curves on it and I want different curves fragments to unwrap as square islands, that way the texture deforms and follows the contour of the object. You can see on the attached image: On Top: Blender - After some vertices alignment and some tweaking it kinda works, but it's not an easy process. On Bottom: 3DCoat - Not to mention that I created more islands, but to illustrate the point it works, that's where I'm at. Problem been that I'm not even sure I can turn those islands into rectangular shapes. Is there any way to do it? Thanks in advance.

Automap UV feature is fantastic, very impressive results in testing. Only issue similar to other automap softwares is small islands, sometimes these are single triangles. This usually seems to be because algorithm does not take into account size, only other metrics like angles? A min triangle or cluster radius would help. This could be separate from automap and just another uv tool that looks over existing seams/islands and merges/welds small island to neighbouring ones. This is useful for avoid many islands on small noisy areas of mesh. Maybe it will need some cuts and islands in areas like this, however main advantage of automatic uv feature for me is making UV islands of the bigger broader shapes/volumes. Provides a good starting point. Presently either do manually or have to cleanup hundreds of islands. One mesh have 3k islands but only about 200-500 are reasonable size the rest need to be removed/merged. EDIT, sorry just notice on mobile there is feature request section, could this thread be relocated there please? http://3dcoat.com/forum/index.php?/forum/14-feature-requests/ -
Hi, I've got a rather simple question. Is there any way to use the UV Room's Auto Scale command without triggering 3D Coat to automatically realign all UV islands as well? The problem is, that I painstakingly arranged different 'sub-islands' in Cinema 4D, so that things are a little more organised once I start working on the global UV map in Photoshop. All I need, is to scale all these sub objects' UV maps to the same size. Clicking on the Auto Scale button makes this simple, however, it instantly messes up my initial layout, by rearranging everything as it sees fit, meaning I have to recreate my layout from scratch. If you could Auto Scale without any realignment taking place - let's call it "Auto Scale In Place" - there might be overlapping islands, but I could quite easily move things around, keeping my initial layout. There would still be work to do of course and it would be fiddly, but it would definitely be quicker, than having to create the entire layout from scratch. So is there a way to achieve this in 3D Coat? I haven't been able to find it. Or would this be a feature request for a future update? Thanks for letting me know!

Hi everyone, I'm wondering if there is an easy way to stack islands when they have the same element, like in this example, I made a tree with many leaves and the UV map would look like this: http://i.imgur.com/A72DcZL.png So if I would do that manually I had to scale and move every single island and it would not only take a long time but also never really be accurate (http://i.imgur.com/mjWIKHf.png). Is there any way to do this better? Or at least a way to scale all the islands equally so I'd only have to move them manually? If not, maybe in another program like 3ds max? Thanks!
