Hello! I have a problem with a VR project (for Oculus Quest 2, if this is important). In this project there is a number of monitors with important information on them, shown on animated materials, which I’ve made using sprites (in Piskel). So the problem is that one of the materials look ok for the first few seconds of animation playing, and then suddenly gets heavily pixelated, so it`s hard to see the symbols on it. The material looks fine on preview though. I haven’t tried to redo the sprite from scratch to see if it was a problem - honestly, it’s exausting so I want to exclude engine things first 
Maybe someone had a similar problem, I would be very grateful for help!
