[Fixed] Missing Polys When UVing

[13car118 0]

I exported my model from Zbrush as an FBX (Ascii, not binary) but when uploading it to UV in 3Dcoat the spherical buttons are missing their faces and do not want to automap as the other body parts have. I haven't had this issue before and when testing the buttons alone they imported fine. But when importing with another subtool, they are missing polys. I have remade the buttons but still have the same issue. I also double checked that the normals are the same way and tried a few different settings to no avail. And lastly I have tried using an OBj instead of an FBX, which kind of works, but is no were near as simple because it automapped the  groups very oddly. Not sure what else to try. Thanks in advance!

Hi

all the UV islands are inside UVspace 0,1 ?

3DC ignore anything outside 0-1

I look into it. I am new to 3D coat so I dont know what this means. Where would I check for UVspace?

On Zbrush before export it, can you ?

This is a common problem i know often when i import mesh with NGons.

3dcoat doesn't like them, so to avoid this, be sure that your mesh has only tris and quads.

 

this may also be due to degenerated mesh like for exemple if you made a copy of your sphere in zbrush and pasted into the same mesh,(witch means 2 spheres over each other), if you export meshes with points with identical position, you may have them fusionned into 1, witch will cause errors.
