Yep, I was testing the trees out on the standard map (I’m working on 4.3, didn’t want to risk moving version mid-project; I did try everything on 4.5, same results though) and in my project map which isn’t anything fancy, it’s the same standard map just an extra cam or two, my own meshes and a slightly rotated directional light.
I feel like I tried every possible combination by now. Best result so far was to make the mesh movable, but then there are no shadows at all, which isn’t exactly what I need.
