I'm trying to fix an issue I come up against where the longer distance, low poly version of the tree objects shows the colour of the trunk and not the leaves. This makes the views with lots of trees look far less realistic. I tried exporting the collada to Blender, but it won't load up for some reason. I wondered if there was a way to edit these in the world editor. I haven't had much success with the shape editor. Thanks in advance for any help.
