[C4D] I need help! / corona makes chaotic render URGENT HELP

« on: 2020-11-24, 15:30:08 »

hello world
im facing a big big problem. when i hit render corona renders this really messy ugly (geo) frame. what ive found out so far. it does it at every frame. i started deleting stuff and it might be from the dynamics. in standard renderer everythings fine. also when rendering an animatic everythings fine without any changes to the scene. so it must be corona that causes the issue.

I NEED HELP ASAP

thanks : )

[C4D] I need help! / refraction noise / optimization (?)

« on: 2019-04-19, 12:49:26 »

hello world

im sure thousands of questions are asked about noise reduction. im rendering a scene with a gem stone (ruby). naturally cuastics and dispersion are on but when i do have them on, rendertimes are impossible for production. so i turned them off and managed without. but at UHD (2160x3840) the rendertimes are still a bit too high. now, maybe corona is like that and rendering refraction is in general a bitch or there is some optimization to make. i would hope that i can tweak something in the performance tab. unfortunately i cant share the scene file but i have 2 meshes in the scene. one is the ruby one is a frame that holds it. i used the sky object with a corona light material as a hdr to light the scene.
the render you see took about 1h 30-40min with 25-30 samples. i know that distance should dramatically influence the rendertime. i need it to be that close though. so rendetimes so far take around 2 hours.
