So I've been messing around with SpeedTrees for the day and have finally gotten the hang of it. Only problem is that any leaves or fronds that I use on the treas are lit properly from one side, but the other is completely black! Changing the shadow settings on the mesh doesn't make a difference, and while I'm mainly using the "Nature/Tree Creator Leaves" shader for my frond material, the "Fast" version of the shader doesn't work either. These are the only two shaders I can use and I have no idea what's causing these to turn black on the other side. The lighting in my scene is fine as you can tell on the surrounding terrain, so... what gives? Using Unity 5.5.0f3.
