[Solved] UV areas missing - greyed out

Recommended Posts

Hello,

this is my first time trying out 3d coat and i' ve been bumping into the same problem on a particular model i'm working on. After i add some seams, change my uv layout and then press UV Unwrap some areas on my model become grey with no checkerboard projection on them and they also dissappear from my uv set.

I have checked my model and cleaned it up twice by now, making sure there are no weird areas but i have no idea what is causing this.

Any ideas?

Hello Carlosan,

thank you for replying.

Import settings i leave at default and i have not created a separate UV set (deliberately at least). My model is one mesh and i want to have one texture at the end.

Deleting unused UV sets didnt fix the problem.

i import my model i press clean seams and clusters.

i create some new seams and then i unwrap again. thats when some areas get greyed out and dissapear from my UV set alltogether.

I'll just attach my model here so you can take a look.

When i open the model, found that UVs are different that showed on your current pic attached.

Anyway sorry but i cant find any issue.

Are you using latest version ?

I opened the file and as i hover over the problematic areas (the ones that greyed out) even though the checkerboard is there at first they do not show up in my UV set.

As soon as i hit unwrap the same thing happens. Those areas become grey and lose the texture information.

One problematic area is around the grill on the side.

That is so weird...i am not a UV expert but i really cannot imagine what is happening.

Maybe i could try the new version..

I was checking the model and have several ngons. 

Remember -before import any model for PPP- to always check faces to avoid it. 

I changed nGons by tris and quads and imported and unwraped the model again.

Please test now this new version.
