Speedtree Overlapping UV-Lighmap Problem

Hi Everyone.
I’m using Speedtree models for my project , I’m having this overlapping UV issue even the UVs are not overlapping and the Light Map Coordinate index seems to be right too.
I’ve tried generating Lightmap UVs but again getting lighting error with different overlapping percentages.
I’m really getting frustrated and fixing it is taking me lots of time and yet I have no results.
Some of the models are working properly but some of them not.
I’m using spm files bdw.
Thanks in Advanced!

hmm, I dont see anything wrong with the file :confused:

Well, That’s what makes me really tiered , Everything seems to be fine.:frowning:

might be smart to post on the speedtree forums, see if anybody encountered same issue.
