Have an invisible part with a decal, and use a high Color3 value on it, such as below.
This gives it the illusion of “glowing”.
Make sure either ShadowMap or Future lighting technology is selected, and that EnvironmentSpecularScale is set to 1 alongside GlobalShadows being true.
While play testing directly in studio, the place will randomly light up in that decal’s Color3 value. This also happens during Team Test as well. This does not happen while building or scripting in studio.
There isn’t a concrete 100% reproducible way to make this happen, but more often than not this seems to happen only in large or memory-intensive places. Happens with and without plugins.
While it should happen to any large place, here’s a group place we’ve been working on that it happens on as an example. Press ‘C’ to fly around (and to spawn the asset that causes this problem). Confirmed to also happen in my other places using the same asset.
Here is the source file for the asset that has the large decal Color3 values. Press C on your keyboard to fly around, but you probably won’t encounter the glitch here unless you insert it in a memory-intensive place like above.

Studio Playtests should not exhibit any lighting changes (especially ones that are blinding!). The colours should stay neutral.
Here are a few proof pictures and footage of it happening in real-time:
This asset was made 1 - 2 years ago and only recently did this issue come up so I suspect a lighting change in mid-March started this problem.
Few options for a workaround:
- Leave EnvironmentSpecularScale to 0
- Turn Global Shadows off
- Don’t use such high Color3 values on a decal
- Rotating or moving my camera around seems to make the light fade away temporarily
