vray env. fog..constrain to light cone.

id love it if you could do a more traditional volume light effect, where the fog is only visible in the cone of the light.. as at the moment its quite hard to get a nice dense volume light without fogging the whole scene unacceptably.. would also speed up rendering...

Dumb workaround, could you constrain a cone object to the light and pick that in your volumetric panel?

yep i think so.. but then you have to fiddle around with falloff etc.. and would be a bit tricky as the falloff would be even all the way from the tip the base.. meaning either it would have a hard edge at the wide point or dissapear near the light source.

ideally you could specify a spot or direct and it would handle the falloff automagically.

Very true - It needs a bit of work to make it truly useful in more situations - I was having a fiddle with it to try and make some cloud shapes last night so with a few more features it could be rather useful!
