Light replacement script?

[ben_hamburg]

Hey there,

did some R&D with the particle shader, particularily I was, like always, being foolish by trying to render the particle shader with the same lighting setup as the rest of the scene.
Got rendertimes of 8 hours for a 720p frame, remembered that I´m supposed to render with separate lights.
So I started matching direct lights to the vraylights and domelight I had in the scene and rendertimes went down to 4 minutes...
I think this info should be in the manual or at least a sticky in this forum...

I´m still having a tough time matching the standard direct lights (with vrayshadows enabled of course) to the scene lighting, so I was hoping someone knows of a script that does that automatically...any chance?

If you have a scene that renders 8 hours versus 4 minutes due to changes in the lighting setup, the reason for this should be examined and automated from the plugin, instead of worked around by adding stuff to the docs that nobody reads anyway...

Well, if Phoenix could do that automatically, that would be swell...but I think a script like that would be useful for a bunch of other situations as well, like rendering hair&fur.

Ahhh so you're meant to render particle shader stuff (foam? splash?) with a separate light?
do you just have a direct in scene with INCLUDE only for the particle stuff?

I have a couple of direct lights to match the different light sources and render a separate pass. If I had them only include the particle shader stuff, I wouldn´t get correct shadowing from the other objects in the scene. Its always a lot of trial and error though: I have to render one frame with the original setup to know how its supposed to look and then create direct lights, place them correctly and match intensities and colors, so it looks right, because there is only so much I can do to match it in comp.
Especially when lighting with Domelights, that is quite time consuming.
