so i made a light saber on one of my avatars i added a light to the pc version to glow but i want to make it glow on quest. is there another way to make it glow other then a light on quest
Postprocessing and transparency are expensive to render, so they’re unavailable.
Check here for the shaders available for Quest avatars: Quest Content Limitations
Consider using particles / additive to make your sword glow.
expanding what fax said, you shouldn’t use lights on avatars to begin with, there are very limited situations where you could but more often than not you should be using emission instead to pull off glow effects like these
