How to override brightness of VrayLightMtl?

[oluv]

I have an object with a textured vraylightmtl assigned to it. i have to crank up multiplier quite a bit to let it emit enough light for the scene. unfortunately now the texture is only pure white.

what trick can i try to bring a bit back of the texture without loosing brightness of the light?

i would like render it in one single pass.

i tried composite-material but didn't achieve the desired effect.

 

i hope someone can help!

 

thanks, o.

Haven't tried this cause I haven't had to do this in a while. However, I've run into the same problem you have in the past. Maybe you tried this, but what if you create a VrayOverrideMaterial, in the base of the material you can give it either a basic vray material or a vraylightmaterial. this would just get the material to look how you want. then in the GI material slot add a Vraylightmaterial. this would control the brightness while the base would control the look ............(in theory? anyway) I may try this too just cause I'm curious and we do tend to use a lot of cove lighting......

thanks for the tip. but for now i did it another way. i just duplicated the lit surface and turned it invisible to camera. i assigned the desired material to the other one and voila!

but i had to offset the other one slightly in order to avoid coplanar rendering-artifacts as increasing secondary ray bias didn't help at all.

well a bit more work than simply applying a vrayoverride material but i will try it.

My suggestion would be to set your vraylightmtl to give the proper appearance that you want, and then add an actual vray light (set to invisible) into the scene nearby to give the illumination that you need.

 

This will give you better control over your light type, color, subdivisions, etc... and will lead to a better light quality in your scene.

what if the object is some neon text

how will vray light help in that ?
