Using model from Blender in Amnesia?

[genmills]

Hi guys,
I'm trying to build a good deciduous (not a pine) tree to use in an outdoor map I made in Amnesia.

EDIT:
Woot woot! I figured out the Blender texture problem! Now all that's left is getting the model into Amnesia...

Could anyone point me in the right direction? What are all the steps to go from a model in Blender, to a model that can be loaded by Amnesia? I've looked for tutorials, but they are all so horribly written that nobody without major experience in modeling for games could understand them...

Thanks in advance!
