LWF and Afterburn - how to brigthen afterburn?

[Morne]

Hi all

Afterburn clamps the colours of particles when you use LWF (phys sun,sky,cam)
Is there a way in Afterburn to make the particles brighter?
Any other way to make it brighter except for giving up lwf?

just render your afterburn as a seperate pass.
It will give you more control

[Morne]

as in a beauty pass with scanline to get the correct colours or as in just add a afterburn render element and change the colour in combustion?

[jacksc02]

scanline or vray with everything else matted out

[Morne]

does this also apply to dreamscape and vue?

I'd imagine dreamscape anyway - it and afterburn both use the same volumetric renderer so I'd say neither can do floating point colour. Vue itself renders to exr so it can do float but there's no integration with vray just yet so you'd have to render different images and comp them either way. As an aside a lot of studios seem to render volumetric smoke with three different lights - pure red, green and blue from different directions - then in the comp they can use each channel to control the look of the smoke in terms of how hard the shadows are, and what direction the light is coming from. Rather flexible stuff though I've never done it myself.
