I'm attempting to animate the Alpha value of a basic material using the Principle BSFD surface. However, I've noticed some strange shadows persisting, and I'm unsure how to eliminate them. The Blend Mode and Shadow Mode in the material settings are both configured to use Alpha Hashed. I'm relatively new to Blender, and I'm certain I must be missing something obvious, but I can't seem to pinpoint what it is. Any suggestions would be greatly appreciated.
