As you can see, the shadow is tweaking out, shaking as camera moves.
This comp is using classic 3D. Camera, the background blue (ocean), and spot light are in this comp but the map is a nested comp, also using classic 3D. The map layers are shapes created from vector layers.
Ive tried changing from spot to parallel, moving the light source, adjusting the shadow diffusion/darkness, turning motion blur off/on, different camera focal lengths, taking project from 8 to 16 bit, adjusting samples per frame and adaptive sample limit in composition settings, and much, much more..... no luck.
So frustrating. I am not trying to do some crazy stuff here.
