I got bored with caustics so i am now able to use Luxcore GPU OpenCL for fast renders, and no fireflies as long as you dont use the sun lamp.
It uses a spotlight and a HEMI light with an JPEG image rather than HDR( i think a large HDR would cause the OpenCL problems if i remember) Non the less i really like the results.
I want to get a water simulation of milk coming out of the jug and into the bowl, but dont know if it will be possible… Using Luxrender volumetric material of course.
Got the fluid simulation working ok, but making the milk material is a challenge. Apparently milk can have thousands of scattering events before the light comes out. As you can see so far ive only been able to make it look like coffee.
interestingly Luxrender is using pure OpenCL for this so looks like AMD OpenCL cycles could support volume rendering in the future as well.
If you’re wondering why the first renders look so clear, its because i ran it overnight, in GPU mode, i heavily under-clocked the card so as not to use too much electricity. Still it managed 24,000 samples per pixel.
