For a lot of my armor skins, I made some emissive textures by upping the Color3’s, and it looked good in studio, and it even looks the same in game. But when I actually use it by welding the armor to the player’s torso, it doesn’t look how it’s supposed to and doesn’t glow at all.
The left is what it’s supposed to look like, and the right is what it looks like after it’s been welded via script
The same way normal parts are turned into mesh parts for R6 like shading artifacts caused by hats is removed is because a player model becomes joined in several ways once put into a model. A late explanation but I am sure you wanted to know.
