New lightning system

[FabioHartmannFernandes]

Is there any news about the development of the new lightning system?
For scenes with multiple lights the current system is inviable for animations...
I'm rendering a scene (4000x2000px) with multiple lights with 3 titans and for a clean render i would have to wait for 2 or more days...
Can you comment about the development of this new system?
Is there a schedule to implement it?
Thanks a lot
Fabio

check first new GI_clamp parameter in 2.04

[FabioHartmannFernandes]

I´ve tried...

Doesn´t change much...
Has less firelies but...
The grainy areas still there...

GI Clamp 100000 (original value)


GI Clamp 10


2000 samples / PMC

The scene seems noisy after 20 min of render.

try 0.5-1.0

[FabioHartmannFernandes]

GI clamp 0,5

The interior lights disappear...
The noise still there...
PMC 2000 samples
render time increased to 26 minutes

I recently tried new thing. I made my lights very small like a small tiny square, increased power because of it and in the light options where it says samples I changed 1 to 1000 seems like it fixed the noise and fireflies. Maybe it will help

i see that you need to do experience before trying bigs. You are not making good tests about my advice. We have done some tests on GI clamp. That was very usefull. Also you should understand what's causing fireflys. Try to lower emission values, increase iso or exposure. Try to find good balance between things before appyling textures. Adjusting the lighting over textured models, this is not good idea. I would hope that i could explained what i mean. I'm a developper no longer and i can only give some advices.

After 46:30 hours of render... isn´t enough


PMC 4000x2000 GI clamp 1 Caustic blur 0,5 rayepsilon 0,001 rrprob 0,25 max rejects 500

I tried a lot of configurations...

I tried to change the lights from octane lights to planes with blackbody emission... then i´ve tried planes with texture emission...

Then i´ve tried IES lights (don´t do that)... infinite slower

I´ve tried to tweak light sample, GI clamp, ISO, exposure, etc... but the noise is impossible to get rid off

I don´t have problems with fireflies what bothers me is the noise... the image is completly noisy..

I need some help here...

Thank you

tried very low poly emitters? always make them as low as possible
ah i see you tried planes, thats prob a low as it gets

did you try increase light samples to 1000-10000 same button is in mesh emitters. it worked for me
