I created some trees in Blender. The first one was perfect in the Blender preview and I exported, then it was near perfect in Terragen 2. But, then I made a second tree in Blender. It also looked perfect in the preview but, when I got into Terragen and made a population their colors were bad wrong; like the leaves were brownish instead of green. I checked all the settings and they were the same as the first tree. But, what could this be? What settings do I need with a program like Blender? Do I need to create the object with environment lighting and light sources and such or just make the object plain by itself? Any other tips?
