Currently having an issue where lighting is obscured from the bottom-right corer of the room. Lighting seems to fade out suddenly when pointing towards that region. The issue is not only visible in the SpotLight entity, but also the skewing of the PointLights and how ground sprites are lit.

Also, I love Fauxton 3D, and it's been a lot of fun learning for me so far! So I apologize if this issue is a basic misunderstanding or misuse of the extension.

I made a project from scratch to replicate this issue once I found it in-game. Lighting in the demo source (room 4) functions perfectly fine on my version of GMS2, but I'm having difficulty finding what is causing the issue on new projects.

Sorry to reopen this post from a year ago, but upon testing, I think it might have to do with the light variable z; if it's too low, your light might be obscured.
