View Full Version : [Need Help] Volumetric Spot Light for Maya VRay

03 March 2012, 10:06 PM
Hey guys,

I'm working on something right now that requires me to do volumetric spot lights on a set.
We're currently using VRay and I'm totally scratching my head (hopefully not balding anytime soon) on this one.

I know that spotlight with light fog works fine with Maya Software and MR, but it doesn't work with VRay. Unfortunately, it was requested that I use VRay. Now, I've tried attaching VRay Environmental Fog and Simple Fog onto the LightFog attribute but it's a no-go.

I'm stumped. So, hopefully someone out there can lend me a head. Thanks in advance.

Could you share the reason why the vrayenviromentfog is a no-go?

Hmm, I plugged it into the LightFog Attribute, but when I rendered it it didn't show anything other than the standard spotlight hitting the ground, there was no fog rendered.

Now, I might have done something wrong perhaps? I left the VRay Environmental Fog at default so that I can tweak it after I see what it does from the result of the render, but it didn't show anything at all.

Great. Um, thanks.
Wonder if there is anyone else who knows if this can be done.

I don't know if it will work with V-Ray as I'm not experienced with but have you tried the parti_volume method that works well for mental ray?
