Hi everyone,
I’m working on a scene with some shops, lights on materials with displacement and since few hours when i try to render a test, it takes almost 10 minutes to charge the scene before rendering.
Any tips to make the process faster?
Thanks in advance
Update, if i shut down C4D and restart the scene after, it’s way faster.
Is there any kind of problem with the RAM?
Hey RedLab,
today I experienced longer parsing time on a quite simple and not heavy interior scene.
Well, for me, long parsing means 36 seconds… :))) normally it´s 12-15 seconds even in relatively big scenes.
Also when I stop a render, this specific scene freezes for ca. 30 sec. until it starts to render the new one.
Such behavior I experienced wit C4D before using Corona… so I thought it´s a Cinema problem.
I guess this specific scene has some buggy stuff in it… will try to copy paste it, erase some objects… etc.
I read that some people have 15 - 30 minutes parsing time… That would kill my nerves.
However… I don’t see a logical reason why a small scene is now parsing twice a long as much bigger ones.
I have also problems with long parsing time.
I tested it on a exterior scene. 65MB geometry, 1.3GB textures. I rendered 5 passes.
iMac i7 4790k (for IR and normal render)
PC i7 5960X (TeamRender rendered only on this cpu)
IR - parsing time: 1m16s, render time: 1m17s
Normal render - parsing time: 1m0s, render time: 3m6s
Team Render - parsing time: 4m48s, render time: 2m19s
The same behavior also on all other scenes with vegetation and textures..
Can someone explain me, how to reduct parsing time? Parsing time is just too long for such a scene. Render time itself is okay.
Also: during parsing is only one processor working, is this behavior normal?
Thanks you!
I would check the simple things first like if you have a huge texture file when you don’t need it. If there is a magazine in the background and the largest it will ever been seen is 50 pixels wide, make sure you don’t have a 16k image in that material. Won’t render any better, just take longer to sample that huge file down.
Yeah, I guess keeping a scene as clean as possible ist still key. 
I never apply big textures when not necessary, untriangulate imported geometry, keep the number of lights to the necessary, etc…
99% of the times everything just works fine…
I did the same test again but without any textures or materials.
IR - parsing time: 0m25s, render time: 1m47s
Normal render - parsing time: 0m17s, render time: 1m53s
TeamRender - parsing time: 0m20s, render time: 1m8s
TeamRender has clearly a problem to handle textures - at least in my case.. I don’t know, if it’s on the side of corona or c4d.
And no, my network isn’t that bad 
But yep, I have to reduce my textures to get acceptable performance.
