Using Weight Maps

[3dreamstudios]

I'm trying to do a fake volumetric light. I would like to use a weight map to fade out the properties I have applied, emiision, opacity etc... near the end of this object.

Is there anyway to use weight maps in this way...or an alternative thought to doing something similar? For my purposes and render time needs I'm happy with this look but need it to naturally fade away like light does in the real world.

Thanks for any thoughts.

Currently, Octane does not support lightwave weight maps, as the developer explained that there is no reasonable way to gather weight map data at render time.

Although you can achieve volumetrics directly in Octane, my recommendation would be to utilize native lightwave's volumetric lighting and composite that on top of Octane renders... it will look many times better, and it will also render much faster.

Changed the Weight map to a UV map and pretty happy with the results..will continue to develop but this is progress!.

Not looking for more work and compositing as that for sure would work.

For now this is what I've come up with...

A geometric cone with special material...and then a light at the end with IES to mimic the size and scale of the faked light.
