Chaos Corona for Cinema 4D => [C4D] I need help! => Topic started by: albertoiuav on 2023-03-15, 16:53:41

Hi all,
i noticed that using chaos scatter with cinema 4d have big issue when i try to put a procedural noise inside distribution.
The interactive render slows down a lot and it becomes impossible to work with even a single scatter.
Doing the same test in 3dmax works perfectly without any problem.
This forces me to use only splines as a "random" distribution method but it slows down the workflow a lot.
The random distribution becomes very practical and fast to create a good base on which to then work in more detail.
Unfortunately, in Cinema 4d it is not possible for me to do this.
I have already tried it even on empty scenes with a simple plane and cubes.
On all workstations in the studio there is the same problem and it is definitely not due to the hardware.
Does anyone else have the same problem?
Thank you very much

I scattered small cubes onto a large cube with default parameters, with Noise in the scatter distribution, and IR and viewport performance was fine. Could you share a scene that is a problem for you (in case it is some sort of specific noise type), and perhaps a video or something to show the problem you are running into?

Oh also the ever necessary version of C4D, OS, OS version, and version of Corona ;)

Same here, just checked it and all is ok.
-
maybe check that the noise is in UV mode?

Hi albertoiuav,
Could you please also share your computer specs? (CPU model, installed RAM, graphics card model and video memory)
Kind regards.

Hi All and thank you for your reply.
Attached you can find a very basic scene (Sorry but I haven't managed to make the video yet).
If i start the interactive render and try, for example, to change the seed of the noise, already it is beginning to slow down.
If I obviously try to do it with a more complex scene (e.g., trees, bushes, etc.), it becomes super slow.
We have different workstations in the office but for this test i used this one with Cinema 4d R25 and Corona 9 Hotfix 1:
- 3970X 32 core
- 128 gb of ram
- 2x Nvidia quadro A5000 34gb Vram
- Windows 10 professional
Thank you so much

* sorry, i mean 24gb of Vram

Hi there, I'm not getting any issues here at all when changing the seed. And my PC is not the best at all. In fact, it's a dinosaur. What happens if you change the viewport display in the scatter to wire box or dots or even turn off immediate updates?
-
I am not sure what you mean by IR slowing down - in your test scene, if I change the seed, sometimes it takes about 4 to 5 seconds for IR to refresh to show the new results (while the new scattering is shown pretty much straight away in the viewport), and when IR does update it shows it is already at pass 4. Is that what you mean by slowdown, the reparsing of the scene?
