Title: VFB: inefficient at high resolutions
Post by: cecofuli on 2013-04-03, 11:22:56

Hi,
I noticed that at high resolutions >5000 px:

• Corona eats  a HUUUUGE amount of ram.
• 3ds max becomes extremely jerky and to stop the render (by clicking the STOP button) take 2 minutes...

And the scene is easy...
Is it a bug? Or can you solve this problem? VRay doesn't eat so much memory, he has a .vrimg to save memory and create a "Generate preview" during the rendering.
And to stop the render we need some second

Not here to help you, but your render is really nice. One of the best carpets I've ever seen. :]

Thank. The original scene is from my friend with VRay. I just add a new bed, pillows and, yes... a new carpet :)
Oh, yes, and I converted the file from VRay to Corona ;-)

Yes, render 5k eats a lot of RAM here too - 12GB and more.
But no problems with stoping render.

win7 64bit
Thanks for the link. so, there isn't a real solution.
At 6K, corona eats more than 4 GB of ram... :-(

VFX was redone, some of the problems should be fixed/mitigated in the newest build.

Yes, I can tell you that it's much better now. I'm rendering a A3 300 dpi images and the "feeeback" is much better. Also the RAM consuming.
