Light Bleeding through Material.

KraiggC — Mon, 22 Jan 2018 22:18:00 GMT

I have a light fixture, attached, and the light source is bleeding though the body and washing out the wall where the light connects to the wall. Anyone know what's causing this?

Renders beautifully for me.

What's the result at you end? Did you apply the correct materials to the lens and housing?

The image in my original post is how it renders for me. Where the housing attached to the wall you can see a light halo. My Lens material is transparent and my housing material is opaque.

Well what the heck.. I'm rendering with VRay i wonder if that's one of the issues?

Change your settings. Your background is set to "None" I'll bet. Use "Sky".

You mean this?...

That last one was "Realistic". This one is the same one, except Rendered via "Ray Trace"....

Come back at me Kraig; I'm in the weeds with you on this one. What's the story?

Can you make sure the VRay's retrace parameter under Light Cache dialog is checked?

Where's that?

VRay settings I supposed. Not Revit's.

@ToanDN: I don't know who that last post was directed at, but I'm curious to know about the V-Ray setting you referenced; "Retrace Parameter". Where's that one located?

ToanDN — Tue, 23 Jan 2018 05:05:17 GMT

Do you have Vray?

Huh? Yes.

Re: Light Bleeding through Material.

barthbradley — Tue, 23 Jan 2018 05:30:24 GMT

...somewhere inside V-Ray "Settings" maybe? (under the "Gear" icon)

Re: Light Bleeding through Material.

ToanDN — Tue, 23 Jan 2018 05:50:06 GMT

I will need to install vray again to find it.

Darn you @ToanDN! You're my mentor. You're suppose to know this stuff! Now I'm left to wonder. What a pisser!

...edit: I'm editing this to change "D a m n" to "D a r n", thanks to these parochial M.F.'s.

Try toggle between Full Light and Adaptive Light maybe. The one I mentioned earlier is a setting from VRay for Max hehe.

You're Right!!! That is 3-D Max!
