Splashing Einstein

Post by CodeHD » Thu May 16, 2019 4:05 pm

Trying to combine and play with some features...

The model of Einstein's head is taken from http://threedscans.com/.

Other features include blenders fluid, the water was splashed at high velocity against the head, a large relative Sun size for the artistic effect (was mentioned recently in another thread), and the recently fixed PGI that now handles indirect and caustics much better simultaneously.
I added a spot light because the Sun alone only provides light from behind.
The fluid on the floor looks a bit like it is hovering. I believe it is because the floor plane is at the bottom of the water domain. Maybe it is better to have the floor as an obstacle and extend the domain over it? I will try...
The images also have OIDN applied.

Final result (so far) with PGI:

25 minutes total time on i5-9600K, with 9 minutes preprocessing for the cache with the following settings. I really had to go down with lookup radius for this, Lookup Max Count wasn't so critical in turn.

And for comparison, 40 minutes BiDir:

The blend-file is too large for upload here, I will to it separately.

Blend file can now be found here:

And a new render with cahnged setup and some improved settings. More cache :D and more path depth, as default was too low to get all multiple-refractions through water (you can see dark areas in the first image).

This are pretty cool caustics.

Looks incredibly cool! Awesome colors and lighting. I'd adjust the framing so that the head was a bit more obvious and took up more of the image, but other than that its looking supreme 👌
