Author Topic: General Best practice question  (Read 1390 times)

Should each material have it's own UV or is it OK to mix a few materials together on the same UV.

Thanks

On the paper you can do whatever the hell you want. :)

In practice not really : If you have common UVs (not overlapping) but want to split them appart in multiple material (and therefore multiple texture set) you will have the following problem :
- Bad performances because of the amount of texture you will add to process in total on the GPU
- Recombine manually texture after export
- Having to switch between texture set to paint some details, which add some loading times and slow-down in your process

If I can get it down to 2 UV's is that OK? Is there a number of UV's I should exceed as a general rule?

The more powerful your computer is, the more texture sets you will be able to handle smoothly. Two texture sets should be okay in general on any configuration.
