The one from my post was an incorrect link, to the same one fused posted instead of the new one. It is updated now, please make sure you try that one :)

O lálá, confirming!
- Used the updated build: Caterpillar scene with 2.4.4 after 2 minutes: around 350000 S/s
- Using the official build: Caterpillar scene with 2.2.12 after 2 minutes: around 950000 S/s

But with my scene, it's 120%... I'll try the updated link now.

Wow, that's super confusing :?

At least we have pinpointed a scene that shows this problematic behaviour; thanks for your tests guys! I'll raise it with The Chapman soon :)

I came up with the speed increase using a scene with sunsky only.
The caterpillar testscene uses IBL, I think this could be the issue...

No, it's not IBL.

Quick test with my simple scene after 2 minutes rendering:
Indigo 2.2.12: 64,12 Spp | 428756 ss
Indigo 2.4.4: 161,04 Spp | 1093396 ss

120% speed increase.

So it's got to do with the caterpillar scene... somethin in it must cause the slowdown. It's not the physical aperture diffraction, either.

I only could guess, but there are two "special" cases in the caterpillar scene:

EnvMap & subdiv (displacement)

maybe you could try both for your quick testscene Zeit?!

Hm,
I used EnvMap in my scene... now I'll add displacement to something, and then I will test these two in junction.
This is so strange.

Aha, it's getting slower.
when only subdividing something by the givn Cindigo tag without using displacement, 2.4.4 is getting a little slower... plus, it results in faceting e.g. losing phong values.
But it's not getting that slow as with the Caterpillar scene...

Because I have a PC and the above build of 2.4 is for mac?
Apologies, it was really early in the morning. I think I saw the .3 in the release version and somehow concluded that it wasn't 2.4. :(

Hey guys,

new day, new mac build ;)

I fixed the colour difference to previous Indigo versions by changing the default RGB value and fixed a few input issues with the light layers.

Thanks, Fused! Downloaded.
Yes, I´m trying now with the pins scene of David Mullen and:
Indigo 2.2: 594.000 S/s at 30 seconds.
Indigo 2.4.4: 658.000 S/s at 30 seconds.

So we have real performance improvement with 2.4. I meant S/s, not spp, in previous post (sorry!). ¿What makes caterpillar scene to slow down Indigo?

Thanks, Indigo team!

Subdivision of displacement is way slower in this build!

Hi all. I just wanted to point out a little problem with the usual fireflies. Attached, are two images: same scene, with emitters turned ON and OFF. The OFF image (sun/sky) is "almost" clear, even if a little more calculation is obviously needed.

With emitters turned ON loads of fireflies appear. The box containing the emitters is REALLY basic, and the "walls" of the box are simple diffuse mat (the plaster material), no metals nearby or anything. I can't think of anything simpler than that.

The artifacts look like fireflies to me, at least. Could it be something else? More calculation needed? I think I'll leave Indigo running the whole weekend, so perhaps I'll get a more accurate result next monday.

Hi Pibuz

Definitly looking like fireflies, but I can think of one way to perhaps tweak this... Do you remember the time wen Indigo had no layers ? Lights were in need for muuuch power to show beside the sun. Well, try to set the light powers as if you were to render on a single layer, for a raw output. Hopefully you are not doing this already...

That's from "my theorical ground", real implications are well above my head as you know ^^ I hope to be back at smurfing with Indigo soon to tell by myself !

edit: on a secong thought, looking for a visual balance might not even be sufficient; why not try to overflow the sun with lights, then dim them within Indigo ? It has to do with relative light powers, that's all I can say in fact :/

yes, that's the way to go!

Set the light power of the emitters 10 times higher and into a layer, in Indigo then reduce Layer intensity to 10%.
It simply seems that your emitter boxes are "lux vise" low and not important enogh for Indigo, so it just uses 0.1% of CPU power in calculating this lightsource!
Thats usually the way to with IES light, to solve fireflys and slow rendering for lights.
