Lux is lit, it's absolutely my go-to engine. If anyone is looking for a FOSS project to contribute to we could really use a bevel shader. In terms of accurately rendering participating media and caustics no other open source project holds a candela to lux. ;) Mitsuba doesn't count as it's too slow to be of practical use. (all that being said I would love to see Appleseed dev pick up again, it would be really nice to have a production focused spectral renderer around again)
