All I did was add a png to the material, then I drag the material to the landscape (following the tutorial on landscapes) and then it compiles shaders and crashes once it finishes. Every time. No idea what else to tell you.
Ok I figured it out. I was trying to add tessellation to the landscape and the engine didnt like this. Problem solved.
I would also suggest staying away from .png, it’s fairly unstable and has some issues in the engine. I stick with .tga personally.
