vray light material doesn´t work

[max montana]

hi, i face a problem i never had before. interior scene, vray sun/sky+physical cam. i want to light parts of the roof by objects with the vraylight material, but it doesnt work. when i try it in other scenes it works. i compared the settings of the scenes, all the same... i am at a loss...

also tried it with max standard material + self illumination checked, doesnt work...

When using exposure you need to turn the output of the light material up, 200+

checked it, after that i tried to solve the problem i wrote the previous post and by writing the last words i remebered that the vray sun intensity is much higher than the direct light, and the physical cam compensates it. ok, i just had to rise the level to 1000 and it worked. perfect forum where i solve my problems just by writing about them

thanks rerender, you are to fast for me...
