Controlling texture density?


(Xiuming) #1

Is it possible to control the texture density of my Blender model?

Specifically, in Blender, I am using a "Mapping" node that scales the texture in x, y and z directions.

After some explorations in Sketchfab, I didn't manage to find such an option. Maybe I can reformat my Blender model so that Sketchfab can "inherit" the texture density?

I don't think you can scale a texture in Sketchfab, but scaling the UV of your model should do the trick :slight_smile:

Hmmm, could you elaborate a bit? Do you mean scaling the texture image? Thanks!

no he means scaling the UV coords.

In regards to texture mapping in CG, textures are never scaled, it is always the UV set/s. If you did not unwrap your model in blender and you are using one of the built in projection modes, it is actually unwrapping the model internally. So when you apply scale it applies it to the internal unwrapped UV coords. To recreate that effect for sketchfab you need to do the unwrapping explicitly and then scale the UV coords yourself.

If this is all beyond what you know about cg I suggest looking at a few tutorials on uv mapping.
