second set of UV coordinates

Support Basics & Interface

I want to make two UV coordinates in Blender with two textures. How can I make this?

Hello endi
You can only apply one texture at a time to the same faces selection!
But you can apply different textures to different selections inside a
model, just load or assign a new texture.

Thanks. But I need multiple UV textures on one face (with 50-50% opacity for example).

I am now sad. :frowning:

Hey endi

You have two possibilties:

  • Join your two textures in gimp or photoshop or what ever by putting two layers over each other and adjust the transparency. Save as new texture and apply this one to your model.
  • You can copy your object and make it a little bit bigger (or smaller) than the original one. Now you can apply one texture to the first one an the other to the second one. You just need to have the alpha-values in your texture-picture.
    The second method is not really elegant and not suited for all circumstances and objects…

hope that makes you a little more happy :wink:

Yes, yes, this tricky.
But unusable for games. (I use Blender for PS2 game developing. I make the modell+UV and we put this into 3DSMAX.)
For example, I need a secondary bump UV texture.

Wait a minute. Do you want to apply two different textures with two fully different sets of uv coordinates? Or do you just want to use your uv coordinates with a color map for the colors and a separate bump map for the bumps? If so, it’s easy - instead of using the standard method for bringing the uv image over to the model, just click “uv” in the Material buttons where you choose your mapping type (orco, world, refl, etc.). That will use the uv coordinates for the textures you spec out in the rest of the material. I.e., click “uv” as just stated, then use a texture as a “col” map. Make a new texture channel, load your bump map and, choose “uv” again and set the “nor” button.

Hm, yes, this is good for bump-uv.
