How to fix imported materials

[kitfox-com]

I’m having trouble with Unity setting bad values for my materials when I import an .fbx exported from Blender. Here is a tree where the leaves use alpha transparency - however instead of making just the alpha transparent, the alpha seems to be ignored and the entire mesh is being rendered as transparent. I would like to tweak the shader values manually, but they’re greyed out.

How can I change the material that Unity created for this object?

Import the texture into the scene and create the material from scratch and apply the texture to it. See if that works
