Very disappointed by Octane

[scaphoide]

Trés decu par Octane pour les scenes intérieurs. Il y a un grain de folie.
Voici une capture de l'ipr en action pour une scene d'une simple salle de bain avec 4 lampes et 1 environement extérieur avec 1400 samples en 7min 40 en 1280x720 pix. J'ai supprimé tous les matériaux Glossy et triplé tous les murs et polygones suppérieurs à 4 points, mais c'est toujours aussi mauvais.

Si quelqu'un connait les bon truc pour optimiser ?

Very disappointed by Octane for the interior scenes. There is a noise of madness.
Here is a capture of the ipr in action for a scene of a simple bathroom with 4 lamps and 1 daylight environment with 1400 samples in 7min 40 in 1280x720 pix.
I deleted all Glossy materials and tripled all the walls and polygons higher to 4 points, but it's still as bad. Very bad.
If anyone knows the right trick to optimize?

Hi,

It is hard to say how to improve the rendering performance without take a look at the scene. What kernel are you using and with what settings? Usually for this kind of scenes the direct lighting kernel works fine and it is faster. Also the light sources size, or their sampling rate parameter. can help to clean the noise. Tripling the ngons makes no sense to improve the rendering speed, the plugin triple them at render time.

The new 3.06 adaptive sampling could also help a lot with this kind of scenes. Are you using it?

If you want to share the scene or send it to me, I could take a look at it to see how to improve the render times.

Thanks,
-Juanjo

As Juanjo says, it's hard to give specific optimization suggestions without the scene; generally speaking, however, it depends on the kernel. First thing to try in PT: raise caustics blur above 30% and get rid of a couple of zeros in the GI clamp field. And even more generally speaking, keep in mind that all pure GPU renderers will struggle with interior scenes; Octane can outperform the native engine in a variety of scenarios, but interior rendering is generally not one of those.

hi ,

the first "trick" is to understand what a PB Renderer is! here some examples...its not the software

I see what your problem is. You only have one GPU.

Bonjour Scaphoid !
Problème surprenant ! Combien as-tu de carte GPU ?
