I have got light issues on 5.4, I made a backrooms game so i use hdri_backdrop for lighting other than it will cost me lost of fps. When i add hdri and delete the directional light (cuz directional light is pointless because of roof model) My models has got 0 colors. I literally dont understand because in 5.2 everythings works perfectly.
