I do a lot of tree modeling. I used to model for Unreal back in the UT3 days, but moved on and have been working with Source for some time in Counter-strike GO.
When I model/Uv map my trees I usually have 4 unique branches in the UV space, and overlap multiple UVs on top of each other (since there are so many branches). I do this because I would need too much UV space if dozens of branches had their own space and for a higher resolution branch/leaves.
Ive known that overlapping can cause lighting issues with models but I have read now that UDK allows you to load a second UV map for the light mapping.
My question is: Can I use overlapping UV's? If I cannot can I use a seperate UV for the lightmaps?
Thank you for any help you can give
