Peeps,

Anyone have a tip for creating a volume of gas or fog in KetShot?  I can do it in one of the other render applications I use, it's a great way of showing a beam of light for example, where the light beam will catch on water droplets or smoke particles.  I've tried creating large cubes and making them translucent materials with SSS properties, but I can't get the material translucent enough.

Ideas would be appreciated.

Looks like you will need to wait for version 6.

I did this in 6 beta, tried to make it so it would be v5 compliant, but you can't get to the colour swatch on the gradient map, but for what its worth try

Emissive material rather than Translucent
then set Cellular map type to colour of the emitter
Use gradient map type for Opacity

Have a play  and see what you can get.

My result would have probably turned out better if i had done a cube with displacement/sculpted bumpy surfaces rather than planar, but I just used KS geometry to experiment, so definitely need to return to this and try again when i have a more suitable model to apply it to.

Now that's looking interesting.  I'm guessing that you can make the volume less dense?  It's certainly worth playing with in V6, hopefully we won't have to wait too much longer, I'm eager to get my hands on it for a couple of the other new features too.

Using the Gradient and the Cellular procedurals gives about 8 different sliders that can effect the levels of fog density and turbulence for want of a better word and the transparency levels too, so it's good fun playing to try and get a useable result

Ooohh, now that sounds interesting, thanks for the tip TpwUK, off to try it now!
