Normally my scenes render quite fast, but this one havent even cleared one single pass after a whole night…
I’m on a tight schedule so I’m wondering what would be the reason to make a plan.
It’s a big real estate development and I am making a few shots from different points of view.
(see screencaps; red circle is the position of current camera that I’m trying to render)
I’m using one HDRI
I have 105 accross different buildings and 60-ish lightMaterials
the scene is in Meters
using PT+PT
system is:
i7 5820K @ 4.0Ghz
32gb ram
GTX550
Is it because the scene is too big for Corona? Too many lights?
Thanks
EDIT: Sorry, should’ve probably posted this in ‘I need help’ section.
The scene does not look very complex. Some important questions:
-what is the resolution you are rendering at?
-which version of Corona are you using?
-are you getting any error messages or warnings from Corona during rendering?
-do you have bitmap paging disabled? ( https://coronarenderer.freshdesk.com/support/solutions/articles/5000675862 )
-can you show screenshot of “stats” tab in VFB while rendering?
-how are you loading the HDRI? Are you using Vray HDRI loader?
Some quick ideas:
-do you know what actually took so long? Was it the final rendering or some pre-computation phase?
-are you using displacement?
-maybe you are running out of RAM (which shouldn’t be the case with 32gigs, but who knows) and HDD starts paging?
-you can try enabling UHD cache as secondary solver, maybe it will help
-you still have a lot of lights, maybe this can be optimized? See: https://coronarenderer.freshdesk.com/support/solutions/articles/5000515603
-generally the stats look ok, but you are getting lots of rays/sample, see: https://coronarenderer.freshdesk.com/support/solutions/articles/5000501982
It was saying “rendering initial pass”, so I’m presuming that’s the first pass that took the whole night. The pre-computation seemed normal.
These are good pointers maru, I will definitely try to keep these in mind when I start the next project.
Can’t wait to take my time and get deeper into Corona.
Try rendering the same scene using uber small resolution, if the pass is not loading hours, but minutes thats the problem.
To fix it I suggest using backburner plit render and that would save a lot of time.
Try to render the scene using “One material” (resave with other name, and add only 1 material to all) that will determine if that is the shader problem.
If not, try turning on/off some objects in scene to see if that is the case.
These are useful pointers, I will definitely run those tests to pinpoint the issue.
For now, I just bruteforced it for 20 hours since the project’s due very soon
