Speed up rendering times for fluids 2003-12-17 - By Duncan Brinsmead
Back
Here are a few tips off the top of my head.
1. Set the fluid shading quality as low as you can without getting dots.
Avoiding hard edged boundaries, particularily thin shell elements
in the fluid can help one avoid needing a high quality setting.
One should avoid sudden transitions in the opacity graph or very
high frequency textures, for example.
2. Avoid the billow texture(very slow).. instead use perlin or
spacetime( if textureTime is animated ) with inflection on.
3. If you don't need it, turn off self shadowing for the fluid.
4. If you are casting shadows from objects onto the fluid use depthmaps,
not raytraced shadows.
5. If you don't need shadows from objects onto the fluid, turn off
recieve shadows on the fluid( note that it can still self shadow
when doing this ).
6. If you are raytracing, particularily if you have multiple fluids
you may wish to turn off casts shadows on the fluid.

Subject: Speed up rendering times for fluids
There is many parameters which would influence fluids rendering times.
I need to render quite a lot of it, and even with new machine it take
enourmous times to render animation.
I figure out, I can simulate some stuff with 2D fluids layered,
but for 3D fluids, it would be great if we can have some insight
on render times versus options.
Thanks
