"Imported mesh with XX triangles and YY vertices"

[OlaHaldor]

I have exported the object from Zephyr, brouht it into Zbrush for retopo/zremesh and a simple UV unwrap. I just want to go through this process quickly so I can see how it is and down the road, do a more thorough and quality job of retopo and UV.

The first round, after I had exported OBJ from Zbrush, the message I got upon "Import mesh with UV" was

"Imported mesh with 6 triangles and 4 vertices".

I was like WHAT? I know for a fact the zremeshed object had 5K polygons..

I tried over again. Made a version with 10K.
This time the message upon import was
"Imported mesh with 43 triangles and 15 vertices".


What am I missing here?

Hi OlaHaldor,

can you please share with me the obj file? I don't know if this is the case, but please note that we currently do not support obj with multiple textures. However, we will add multitexture support in v. 3.6 (eta end of January)

I'm not sure what you mean by "multiple texutures" ?

This is what I have done:
- imported 200 images into Zephyr
- Created sparse, dense point clouds
- Created textured object
- Exported the object, brought into zbrush to clean up and make custom uv
- Exported the new object with new uv
- Back in Zephyr, Import mesh with uv

And then I get that message I don't understand..

Here's the mesh.

Multitextures means that you have multiple texture files (texture1.png, texture2.png...) and materials in the same obj/mtl files, but this is not your case :)

The problem in this case is that there are both triangles and quads in the same file. Zephyr supports only triangles so you should convert all the quads to triangles inside zbrush before exporting. Please let me know if this solve your issue!

I tried, but now I get a very descriptive "failed to import file." message. :/
I am positive there is *only* quads in the mesh.
There is a UV map present.
There are no vertex maps or anything else. Pure quads + UV.

I even tried cleaning up the mesh in Modo, looking for stray vertices etc, didn't find anything though.

Hi OlaHaldor,

the problem is that the mesh is composed by quads. Zephyr only supports triangles so you need to convert all the quads to triangles. You are right about the error, it's not very descriptive, we'll add some warning when importing quads instead of triangles

[OlaHaldor]

AAaah right, sorry. I forgot. I'll triangulate the mesh and give it a shot.
