Setting texture correct? [IMAGE]

Ive imported a fbx-model of a tree. It was textured in 3dmax, but when imported I have to add the texture manually.

Problem is I dont know what texture type to set.

I tried transparent/diffused, and it turns out like the first image, and I tried diffused and it turns out like the second image.

Transparent/difussed does work for the texture facing the camera. But youre also are looking past the tree to the faces facing away from the camera, and they disappear completely. So, is there a way to set the model showing both faces in unity?

Wrong part of the forum for this question?

Look up the shaderlabpage, there is this one dealing with your problem, i case you want to write your own shader or tweak an existing one.

Other than that you might want to import the mobile package, which has some shaders.
Try Vertex colored shader “Mobile transparent Vertex Color” or Particle Shader “Mobile Particle Culled”.

Keep in mind that using transparent objects will kill perfomance on devices with higher resolutions. The more and the bigger those are used, the slower.

Finally go to youtube and look at Jessys Shaderlab tutorials, which is just great. There are some movies dealing with alphatesting
