Member gswartz Posted April 12, 2014 Member Report Share Posted April 12, 2014 I just had my first go at creating uvs with 3dcoat and I want to kick myself for spending 3.5 hours doing the same job in modo last night that took me about 15 minutes tonight. Oh well, now I know what tool to use in the future. However I noticed on the uv map that certain polygons around my characters mouth corners were overlapping. As I moved the vertices around to clean it up, some of the uv polygons turned red or blue. I think I understand that this is supposed to indicate stretching, but I'm not sure. Regardless, even if it is, what does red mean vs blue? I've gone through the uv section of the manual but didn't see an explanation of this (though I'm sure I could have missed it). Thanks!

Javis Posted April 12, 2014 Report Share Posted April 12, 2014 Hi! Red means that the area is too tight, and vertices need to be moved apart from one another in that area. Blue means things are too far apart, and the vertices need to be moved closer to one another in that area. Gray means things are just right. Hope that helps!

Member dragon Posted April 12, 2014 Member Report Share Posted April 12, 2014 I'm working on some UVs right now, and I just moved some red-area verts closer to each other and they turned blue, so I'm not sure that right... Unless I misunderstood what you are saying. Quote Link to comment Share on other sites More sharing options...
Member gswartz Posted April 12, 2014 Author Member Report Share Posted April 12, 2014 Thanks but after experimenting, it does indeed appear to the reverse of your explanation. Regardless, as long as we're moving toward gray, I guess that's all that's really important, right? Thanks again Quote Link to comment Share on other sites More sharing options...
Advanced Member FreezeFrame Posted August 10, 2014 Advanced Member Report Share Posted August 10, 2014 (edited) I was wondering also, I check in another software with the grid numbers, squares, etc,... I don't really see any stretching or odd sizes. Ok now in 3D Coat I will get some red and blue. Now if the uv is going to an image size I did in Photoshop. There's no way of making it clear grey..without the blue or red. I guess if I had an idea whether to upscale or downscale the image in P.S.. Is it really worth the extra effort??!!! I would have thought that I have room and should make the image a decent size filling the uv texture space....??? Because sometimes I will start with a texture layout.

Contributor Tony Nemo Posted August 10, 2014 Contributor Report Share Posted August 10, 2014 When ordering my UVs, I enlarge visible areas (turning them red) and shrink non-visible areas (turning them blue). What should I do? Quote Link to comment Share on other sites More sharing options...

Regardless, as long as we're moving toward gray, I guess that's all that's really important, right? Thanks again Sorry about that. I am using multiple applications, each of them are a little different. I believe I confused 3DC with Modo in this case?

Not much if this is what you want. 3DC will also color code polys based on relative size to each other. So it can be a little confusing when working with UVs. It's relative size of vertex to vertex, and poly to poly. Quote Link to comment Share on other sites More sharing options...
Javis Posted August 11, 2014 Report Share Posted August 11, 2014 I would like to mention that even if you get very large or very small polygons and you get saturated red or blue polys, and you know your UVs are laid out fairly well, there is no cause for alarm. Your UV map is probably just fine and you can do your texturing. It's just 3DC saying "Hey, your polygons are slightly disproportionate from one another!".
