+ | |||
+ | The same tree can be exporting in many different ways to accomplish different things post-export. The best texture resolution when unwrapping can be obtained by stacking everything. | ||
+ | |||
+ | Another common export is when you wish to sculpt a trunk in a third-party application. In this case you would want branches and caps completely unwrapped into unique UVs, but everything else could still stack to save on texture resolution. | ||
+ | |||
+ | And finally if you wish to have complete freedom when painting on a tree mesh, you could unwrap everything into a completely unique UV mapping. | ||
