Long time no see! I got a new challenge for you Tell me whats going on... I started to play with cubemaps few minutes ago, and tried what happen if I change the cubemapsize from default to 64x64, and another one to full res. First problem appeared when I tried to build cubemaps. I had to change the resolution to full on game settings. That was okay and I got them builded, and the reflection look much more detailed and more realistic = better. BUT I got horrible floating light spot/orb in the middle of the room after building cubemaps. See the picture... Note that I have omni light on that coordinate on my map, but it's on normal portal map settings: light blue, 200000 etc...,
Anyone else got that problem or know why that happens?

Is the orb there before building cubemaps or appears right after doing it?

right after but I solved i liket to not have over 64x64 sized cubemaps on map.

I've never actually fucked with those options, that's a pretty weird thing for it to do.
