That's not completely true - at least in the VFX industry we've been doing brute-force SSS (with multiple scattering) for more than two years now in some cases.

That's not completely true - at least in the VFX industry we've been doing brute-force SSS (with multiple scattering) for more than two years now in some cases. Yeah, it can be slow depending on the MFP, but it's usable...
Cheats like Dipole/Dwivedi are still used when they can be, but they often have artefacts and aren't completely correct, so they're starting to be avoided now.
- alkonaut 8y agoInteresting, any particular renderers that do this?
- pixel_fcker 8y agoDwivedi is brute force. It’s just a sampling strategy.
- berkut 8y agoTrue, but it's biased, which still causes trouble with some edge cases, depending on how/where you bias towards - biasing towards point-of-entry isn't always better than not biasing depending on where the lights are, and it's cumbersome to set up for artists (depending on where you bias towards).
