WOW!! Haven't use Indigo since 0.6 and i gotta say it's getting somewhere!! After all the python errors (thx blender for changing to python 2.5 :p), I manage to export with Blendigo, and WTF!! this is great, keep it up

The new Indigo is great.
Much faster and better renders.

Is it just me, or doesn't it take as much from you computer as the earlier Indigos?

Anyway, great job Ono.

many thanks !

you should have a look at the newFryRender's feature... to speed up rendering, they are now using "Exit Portals"...
sort of "capping-geometries" to help rays to stop rendering...

looks like good idea...

interesting paper naxos!

could such a technic be perhaps somehow automated for (some) scenes???!

to me it just looks like the same approximate effect could be achieved by placing meshlights in front of windows, or at least meshlights mapped with a portion of the sky texture.
so what if, once meshlights become texturable, the physical sky is mapped on in a global/spherical way onto certain meshlights that are placed infront of the windows?

"Pitfall. Exit Portals cap the exterior view.
As of this moment (vBeta1.6) Exit Portals understand that
beyond them there's only the environment, and not geometry.
This means that if you're using portals to, let's say, mark a
window, the exterior geometry (if any) will not be rendered.
This is a limitation for interior scenes where there's exterior
geometry visible such as those in Figure 7. Those cases
can't benefit from Exit Portals."

so its basically putting meshlights infront of windows and using the bidirectional advantages of bidirectional pathtracing, as far as i understand.

I still think, that invisible meshlight would be a good solution for speeding up renders like this. I talked to Ono about it and as far as i understood, then it is not a very hard thing to do.
Hey Ono, meshlight in window opening still renders way faster than the new hybrid mode. Maybe it's worth to try the "null" option for meshlight?

If you mean invisible emitters I was requesting that a few weeks ago, along with true volumetrical emision

nice to see your coffee cup around here again dude ^^

Blendigo exprots lights with a null mat.

If you mean, you don't want to see the shape, ther is ONE way....

Make the thing smaller than one pixel (or half a or a third or such, depending on the SS value....)

The other way is, to just don't show the light from camera angle and ensure, that there is no reflection of it...

Hi ThatDude! Nice to meet you after so long time

I want to cover the window openings with meshlights. Try it. The noise clears out way faster that way. The only reason why i want meshlights to be invisible is, that i want to get the direct sunlight to be able to get in through the windows too.
Puting meshlight over window is an old method of geting better and faster light distribution to the room. I'm using it in vray every day. It would not make Indigo more biased cause the solution would still be correct.

Interesting that fry is seeing such speedups from exit portals.. might have to give them a try

Kram1032 · Post by **Kram1032** » Sat May 26, 2007 9:30 pm

uhm...
Maybe, you'd have to make very weak emitters, withg a null as base material

(Or maybe, would be a funny test, a glass mat^^)
