Hi. I made a speed radar for GTA V and converted it with zmodeler as prop. When i spawn the prop, i get a shadow bug (the shadow moves like a plant) I think it's a material or shader issue. Tryed it with a simple block-model. There i get the same issue. Can someone pls help me with that? I fixed it somehow with a material one time, but don't know the material anymore.
