[C4D] General Discussion / Masks in Corona 6
« on: 2020-09-10, 23:52:24 »
Is there a problem with Buffer IDs and Masks in Corona 6? No matter what I do I just can't get it to work. They don't render properly and also the .aec file doesn't bring in the fully rendered RGB files in After Effects.

Whenever I try to render a scene in r21 using Intel CPU AI Denoising the render crashes. I'm using the latest version of Corona Render 4 (hot fix 3) on a Mac. If I switch to Corona high quality denoising then everything works fine. This happens with any scene I have or newly create. Is this a known issue?

[C4D] General Discussion / Motion blur and MoSpline object
« on: 2019-09-13, 17:00:43 »
I have an animation of some book pages being turned. The pages are made from a MoSpline object. My problem is that I can't get motion blur to work with it. Does motion blur in Corona simply not work with a MoSpline object?

[C4D] General Discussion / Prevent receiving shadows
« on: 2019-08-30, 18:14:11 »
I have an object that requires that it receive no shadows. Unfortunately, the Corona Composite tag doesn't include an option for wether or not something Receives Shadows like the Cinema 4D Composite Tag does. Unfortunately the object throwing the shadow needs to Cast Shadows on other objects so I can't uncheck the Cast Shadows checkmark in the Corona Composite tag. And the Cinema 4D Composite tag has no affect (at least as far as Receive Shadows goes). Is there something else I can do? I've tried just about everything I can think of.


[C4D] General Discussion / Trying to reduce RAM usage
« on: 2019-08-28, 17:19:17 »
I have a 20 second animation that uses a high resolution video for a texture. Every time I do a render it goes for about 150-200 frames and then stops due to insufficient RAM (See error message below). Often it's not just Cinema 4D that crashes but my entire machine locks up. I'm on a 2013 Mac Pro, 32BG RAM and r19. I realize I may be pushing my luck here, but are there any render settings I can adjust that would reduce the amount of RAM needed to render my scene? I have tried checking "Conserve memory (slower)" under Performance Settings but I still run out of RAM.

Thanks for any help.

===== Warning(10004) =====
System is running low on RAM. You may experience excessive parsing times and/or crashes. You will probably have to simplify the scene.

4 GB of physical RAM used by Cinema 4D
26.1 GB of virtualized* RAM used by Cinema 4D
32.8 GB of virtualized* RAM used by all running applications
32 GB of physical RAM installed on system
33 GB of virtualized* RAM provided by OS

* virtualized RAM means physical RAM + swap file on HDD/SSD

[C4D] General Discussion / Conserve memory
« on: 2019-08-22, 18:11:29 »
Does checking "Conserve memory (slower)" under "Performance settings" in Cinema 4D help with situations where someone is getting errors due to insufficient memory? I can't find any documentation on this.


[C4D] General Discussion / Render Queue froze
« on: 2019-08-15, 18:23:34 »
I tried rendering 4 different Cinema 4D (r19) files last night. They each saved 108 PNGs to 4 different folders. After the first C4D file rendered the render queue stopped. Everything was properly setup in the queue so all 4 files should have rendered. Is there a known issue with Corona 4 and the render queue by any chance?


[C4D] I need help! / Shadow catcher using Corona lights
« on: 2019-04-18, 19:58:59 »
Is it possible to use the Shadow Catcher material just using Corona lights (and no Sky) so the image can be composted with shadows in Photoshop?
