Rendering takes very long.

[Cyanhide]

So this is the first time i'm using Corona and I made this scene to see hows it goes, but it's taking a really long time.
I set it up last night, and when I came back I was only at the 19 pass. And because of all my lights I still have huge amounts of noise.

Any assistance much obliged.

Kind Regards.

GI/AA balance: 32
Light samples multiplier: 72

This means during each pass you get:
-1 AA sample + 32 GI samples for indirect light
-1 AA sample + 32*72=2304 samples for direct light

All clear?

Now reset everything to default values (actions>reset settings) and don't touch anything if are not sure what it does. :)

Also, if you are using displacement, don't use "world size" option. Always use "screen size".

At first I let everything on default, but the noise surrounding the lights didn't disappear ( even after pass 200 ). Then I searched the forum and found a thread from someone with a similar problem and they suggested to up the light samples.

Ah okay i'l change the displacement, not sure how to work with screen pixels though.

I'l try later tonight.
Ty!

Can you show material of those light spheres? They look very suspicious.

[Cyanhide]

The ones close to the camera are plane glass spheres with a shell mod and a corona light in the middle. Then the majority of the spheres are a glass material with corona-light material in the center. No sure if this would cause this.

I used forest-pro to scatter those spheres, and forest-pro doesn't accept physical lights. Only light-material.

[romullus]

Has that glass material caustics enabled by any chance? And why would you need glass at all? Try to render with CoronaLightMtl or CoronaMtl wit selfillum only.

[Cyanhide]

No caustics, Well why wouldn't I use the glass? I'm playing with the engine to see what's doable and what isn't. I like it hehe.
