This problem is driving me crazy. I have no idea what to do, but the textures don´t show in the render. What am I doing wrong?



I attach the obj file so you can take a look if you want.

Hi PAQUITO,

Yes, please upload the obj+mtl file. This is most likely an export problem.
If you use the deep_channel_kernel in texture co-ordinates mode then you can see if the UV's are getting through ok.
The geometry should be shaded from black (0,0) with Green along one axis (0 through 1) and Red along the other, if the UV's are getting through.
What modeling program are you using?

Thanks
Chris.

I use Modo to export.

When I change to texture coordinates it appears all black.

The obj+mtl is attached.

Ok, it´s solved. Investigating through another forums I´ve found a bug in Modo, where if you don´t map every single poly in the mesh, the uvmap will not be exported in the obj, what is a complete pain in the ass, but well, it´s the only way by now until the live plugin is developed.

I did the mapping again on every poly of the mesh, then organized the map where I want textures, and leaving the rest scaled down to a tiny area of the uvmap, so it doesn´t bother.

Plus, you´ll have to delete the normal map of the obj and also make everything triangles. Some Modo user should find this info practical.

Hi PAQUITO,

Ok thanks, i'm glad you got it sorted.

Cheers
Chris.
