The short & sweet was just fine, thanks!

I'm not going to protest against efficiency.

aha... so small things are better for BiDir...

The size doesn't matter so much, what's important is the size of the entire scene relative to the bit of the scene you're interested in.

aha
so the bigger your scene is, the worse BiDir, if you're just searching a very small part of the scene?

hmmm...
so, modelling a whole, say, forest for looking at just a single tree, wont be that good?

The sky-dome is 100* as big as the scene, right?
Can't you just make the infinite plane stop after hitting the boundays?
Or is this still too bad?

That would be interesting, a sort of "bounding box" sort of plane... maybe not.

Ono,

is it somehow possible to release a document which explains the differences between those render types and for which they are suitable?

claas

.... if this document would be the official manual, this would be even better

Yeah... this stuff should go in the manual.
I'll update it some time..

So, how is bidir for interior scenes??
Let's say we have open concept house and you have lights only in the kitchen. You have to model all the walls of the house and everything else regardless what you want to capture.
I'm rendering some tests as we speak but so far the speed of bidir it's blowing me away...

Thanks Ono

Interior = BiDir needed
Caustics = BiDir needed
basically

slobodan, BiDir speeds up interior renderings?

Thanks for considering the inclusion Ono.

Basically BiDir is better for everything.

There are a few cases I can think of that are bad, but none that would be worse than standard "blind" pathtracing (which is what happens with BiDir is disable)

I did some tests and it seems, that Bidir is bad for exr lit scenes and interior scenes where the only light source is the sun. In other areas Bidir should be better.
