[Solved] OBJ import - broken vert colours


Recommended Posts

  • New Member

Hi,

 

I'm new to the program and am trying to import an object through Sculpt.

The object appears with vert colours derived from the textures but they do not correspond to the uv layout, i.e. they are broken.

If I import the same Obj through Paint the UVs look correct.

Is this a known bug, or is there a solution?

The Obj has all its textures and a mtl file.

 

cheers!

Hi many thanks i already followed that. The imported model has broken vertex colours, why is this?

I need to see what i'm doing when i am sculpting.

Am i missing some step when importing the Obj, such as manually importing the MTL file separately?

cheers,

felix

Hi 

Many thanks again for your help - yes the ply brings the vert colours in perfectly - does the OBJ importer not work in that respect?

Be good to know, because in that tut you sent me it appears to work.

Cheers,

Felix

If i am not mistaken Obj do not store vert color only textures coordinates and material, also no bones.

Oh maybe I misread. I thought we were talking about UV textures. Yes, that's right OBJ does not store vertex colors.

 

Reality Capture provides a checkbox to enable them.......(some platforms do extend OBJ functionality)

This thread seems be a good one, although its Blender specific. I wonder if anyone here has managed to get it to work with 3DC?  - https://blender.stackexchange.com/questions/90890/how-to-display-and-use-vertex-color-from-obj-model

Yes but it's not officially OBJ specifications, so you can't be sure what other software can read it, just use fbx or other supported formats

The same way JPG can store transparency, vector mask, ruler etc, but it can be read only by photoshop
