This is a really odd issue I ran into. Certain items glow after being picked up, but only if I'm not running shaders.
It's the exact opposite with translucent items, however. After picking the item up when the item fades back on the brick, the transparency is an odd form of solidity. Reapplying the item to the brick fixes it until you pick it up again. The translucency doesn't work at all if I'm running shaders.
I can only assume I somehow exported the model wrong, but I have made other items before and never had this issue. Anyone else run into this problem or know a fix?
