View Full Version : Adapt a texture to new UV space??

So I have a model with not very good UV space. I use it anyway and start painting on it. I then remap my UVs. Obviously my texture does not lie correctly on my model anymore. Is there anyway to essentially adapt or reconfigure my texture file to have it appear as I intentended it to on my newly UV mapped model?
Is there a function within any application that when you UV map a model it will change your current textures to match the the new UV mapping?

I am using Maya, Zbrush, and mudbox. I don't want to project anything either.

Thanks a lot

A texture is just a 2D image file. You would have to export your new UVs and bring them into Photoshop along with your old texture map and move/scale/adjust parts of the texture in Photoshop to fit your new UV's. The point is that your texture perfectly matches your old UV's so you have to actually edit the texture to reflect the subsequent changes you have made to your UV's.

In future it's best to try and finalise your UV's before you paint your texture, otherwise just creates a load of extra unnecessary hassle.

Zbrush allows you to reimport a level one obj with UVs that, for example, you altered in maya, while keeping the texture laid out as you painted it

You would still need to adjust the texture to reflect the UV changes though wouldnt you? Or am I missing something?

I use MAX and I know you said you didn't want to project but If i wanted to move around the texture i would bake the texture again but with better usage of the UV space and to prevent any extra unwanted lighting coming from the scene set just set the original textures to 100% self illuminated.

If your texture had multiple layers such as a .psd you could bake to texture each layer seperatly (would be a pain but possible) then recombine them after in Photoshop.
