unfortunatly it doesnt work for me. the problem is that when you see surface that reflects light with propper angle it relfects lot of light but if you cut this area with viewer you are loosing this relfection and if you changing the camera angle but still see that area it also disappears.
for now the only one solution that i have found is to turn off lumen and work with screen space but in this case i need to rebuilt lights all the time that doesnt work to me…
