weird material face error. help please?

[anonymissblondie]

Hi. Ive been trying to upload a mesh via the avastar collada exporter but have been unable toand recieving an invalid asset error in sl uploader. I am however able to upload it via blenders default collada exporter but when i do,  it looks like this(see image)

 the mesh has 2 material faces assigned to it yet, the front material face for some reason is divided into 2 material faces in itself. this issue doesnt show in blender before upload and the mesh only shows 2 materials.

Im hoping someone has encountered this before and can help me solve it or at least avaoid it in future.

 thanx :)

We have a Creation section with a Mesh sub forum where this topic would fit. So don't be surprised when a moderator will move this thread.

Obligatory question. :matte-motes-little-laugh: How many triangles is this mesh?

As Arton said, this isn't really the right part of the forum for this question. That is not criticism, it's good advice, many of the best mesh experts won't see the question in the General Discussion Forum so you they won't be able to help you.

Obligatory question 2: are all the normals pointing the right way?

Looks like there might be a doubled mesh, both in the same spot.

hi all!! and first thank you for trying to help and replying

 yes the normals are all facing correct way, and oddly i thought it looked like two meshes as well but when i deleted faces to see if it was it was not. i havent seen this issue before either and was hoping someone elese had encountered it. in blender, before upload, it shows correctly 2 material faces.

 heres a list of some of the things ive tried;

delete materials inblender export mesh, reimport, assign new materials.

cleanup (if any it showed none) double faces, check normals direction, check for any overlapping uvs

at this point ive already been retracing my saved file steps to find a point where i can go from to redo it, but any info onthis would help greatly to avoid this issue in the future.

 fanx!

I have to repeat my question. How many triangles is this mesh? There is a known limitation (BUG) in the maximum number of triangles per material. Which is 21844 triangles. If the materials have more, there will be more materials created by the importer, and these can be wildly scattered on the mesh.

hai arton fanx for replying. I fixed it . the issue was that for some reason sl was  assigning material faces to random triangle faces . dunno why. I rebuilt the mesh relayed out the uvs rigged etc and even with a few more triangles than the original problemed one it worked fine
