Lighttest with 6 luminous planes along the bottom line. Every luminous surface as one part and rendered with luminous threshold rays min/max =1. This is straight from Kray.

So what we're saying here is that setting each luminous surface as a separate part practically eliminates the noise usually associated with lighting from such surfaces?

yep! Try autoparts plugin found here http://www.kraytracing.com/index.php?su ... oParts.zip
OR set the part by yourself

Question: if a luminous surface is composed of many polygons, is it better to unweld them all and declare each one a separate part, or does it not matter?

I like the surface on your lamp shades. Can I have it?

(No, seriously, can you share it?)

So...for those of us (me) who are new to Kray, with absolutely no idea what's being demonstrated here (both in terms of how this is an optimization and also what feature is being optimized!), could you either explain it, or point me to somewhere that I can educate myself?

(Also, please correct me if I'm wrong that there is no manual for 1.7 yet.)

There is a manual here but not as updated as we wish for yet.

What i show is direct rendering of luminous objects separated by partnames and different rendertest ive done.

Neat renders, though I would love to see more light in scene... Anyway, one thing bothers me though, is why the chairs etc don't reflect on the floor, when the lights do reflect quite a lot...

Lights have luminosity 1000%,floor only about 4% reflectivity. You dont see anything else except lights on the floor.

Can we get an answer on this Silver?

Edit Silverlw: It shouldnt matter.

don't unweld, you want as least lumilights as possible. So only make different sources of light (each can consist of many polygons) each one part.
