Post by: patoaltaco on 2013-04-23, 17:26:31
Hi,

I dont know how to improve it, becouse i get only 5 passes on half hour.

Change all emitters to coronaconatantmap + lights
Light sample don't more then 10 or less
Hdcache to default

wellcome

It would be nice to see a scene. It would have been easier.
My tips:
Try render hiding different objects one after the other.
Set PT samples to 256. Use CoronaLight instead emitters.
Check materials for opacity setting, it's slowdown the render.

Lower lights samples multiplier to about 2.

In HD Cache parameters change PT samples to something like 512 or more.

You can also revert all render settings do default and see if it's any faster and then change them to make it even faster/less noisy.

Ondra said several times that light noise bug is still fixed, but i still do not believe him... :) I would try to remove all corona lights from the scene and use only emissive materials ;)

I think that as long as CoronaLight is internally handled differently than emissive material, there will always be this problem, and it will be just patches on top of patches, so they issue will be deeper and deeper and harder to reproduce.

This makes me really sad as it makes Corona very unreliable in more complex scenes and makes the problem very hard to track.

thanks to all,

i think is relative to ram comsumption an resolution too.. i will try to render it on 4 quadrants and compare times...


Cheers.
