I have a few trees i´d like to use in my scene, i´ve got two problems with them though:
1.: The leaves don´t have the alpha displayed propperly, instead just showing black bg, not sure how to get that displayed propperly.
and worse:
2.: The trees lead to major performance drop when i add them in.
I´m not sure what in the setup of the trees is wrong since they aren´t extremely highpoly or anything and trying the island demo i know unity can handle lots of similar detailed seeming trees in the scene nicely.
So yeah, i wondered if someone more experienced with unity could have a look at them and tell me what i should best change in the way they are set up to be able to use em nicely in unity.
Here´s a zip featuring the tree models and alpha/completemap images:

you can forget about it, the friendly fellas at the unity irc helped me 
Just in case someone wonders the polycount actually was too high and regarding the leaves not showing transparent i didn´t know one should put the alpha channel into the actual texture in own alpha channel…
You need to use a texture file format that supports alpha transparency (such as .PNG or .PSD), .JPEG doesn’t support this.
Didn’t take you long to figure this out on your own!
well,NCarter and JoeRobins helped me on irc
Thanks for having a look and giving me a hand, too though
Speaking of trees, (sry for the hijack,) is anyone else seeing the trees “fall” into place when test running their game? I added a bunch of them from the terrain assets package, and quite a few do it.
