Color information missing in Model Target Generator

October 15, 2019 - 6:03am #1

In Meshmixer, I painted (surface brush) my CAD model, then exported it as a .obj with per-vertex color. When I import it into Model Target Generator (and Unity), it appears without the color I added. Model Target Generator gives me the warning "Color information is missing from this model!" How can I import the color information?

So i am one step further:

apparantly Vuforia does not like Shaders that mix textures (see mixedShader screenshot of blender).

I made both my textures into one big texture and did the uv editing again, eliminating the "mix shader" node from the shadergraph.

When importing to Model Target Generation or Vuforia Studio Designer, i see the texture and in MTG it shows the "coloring" tab green with the message "coloring not required".

But when i use the object as Model Target inside the Vuforia Designer and try to set the Initial Tracking Position, it says again "Color information is missing from this model".

So im guessing the Color information that Vuforia is looking for is not the texture but rather something else which i dont know.

But it didn't work at the model target generator. 

What can I do?

Hi,

Could you please share the .obj file with us to test the behavior?

Please note that when you export the .obj file from your program, you should also get a secondary file which contains the materials/colors. We would need both files.

Thank you.
