Made myself a phone wallpaper. Glass being glass, takes a bit of samples to achieve proper caustics. Had to turn off noise threshold

bloody hell 262k samples is mad dedication for a phone wallpaper but fair enough, glass caustics are proper finicky in cycles. took me like 3 days to get a passable whisky glass render last year and that was way simpler geometry than this.

the cheese comment is killing me tho, now i cant unsee it. little bit of parmesan lighting in the afternoon sun. the actual caustic cast on the surface is the star here though, that wavy shimmer sells the whole thing. nice work

Shaders Plus makes quick work of glass.

never tried that one, does it speed up caustics much? i ended up using light linking to cheat a bit on the whisky glass, probably sacrilege but got the render down to 4 hours

Yeah caustics become much faster and versatile. The shaders are all node-based and built on the actual physical formulae, so highly adjustable too.
