[C4D] I need help! / White contour on mask

« on: 2022-05-31, 18:44:01 »

Hi everyone, I was wondering if anybody encountered this issue with corona, the export is 32bit exr passes into photoshop and I am getting this result.
Hopefully the solution is not to re-render all the camera views, there are so many of them....

[C4D] I need help! / The predictable out of ram usage message

« on: 2022-05-17, 16:19:20 »

Hi, once I again I ask for help on this forum to try to understand how much Ram corona needs, I have found people with more powerful workstations having the same issue.

My setup
Ryzen 7 3700x
32gb ram
rtx 3060 (irrelevant for corona I know)
Cinema 4D S24, Corona 7

I am rendering a simple house, no interior furniture, Grass only visible in the area covered by the camera
500 trees spreadwith surfacespread which is a lot for such a small house but somehow 100 trees don't seem to cover the surrounding of the house, 120 000 grass paches, some plants and flowers (all vegetations are proxied)
Render resolution 5237 x 2500

I receive an out of ram message when rendering, I deactivated all displacements from materials, I unticked keep in memory from all proxies.
But still the ram message, no other application is running during the render.
Because I found no real answer from the previous posts, I assume this issue isn't getting solved any time soon?
Is this issue solved with Corona 8? I hate switching during projects, I encountered some issues in the past...

Is there a way to limit corona ram usage?

[C4D] I need help! / Interior render fireflies issues

« on: 2022-02-24, 00:40:46 »

Hi folks I need some help getting rid of white spot or fireflies in this interior render.
I am using Corona 7 with C4d S24.

The scene is lit by several ies lights + a sun and sky .

I also use light materials for the bulbs, but they emit light at a power of 2. I disabled all the lights visible in reflections, still nothing.
I first rendered the scene and it took 8 hours and the fireflies were still there so I closed C4D without saving the first image because I was pissed.
I had to re-render this one to show you the scene.

What do you think might be causing this?
I am not a programmer but I was wondering, do perfect render engines exist? I mean a render engine where you put your light and your materials and everything just render perfectly without you having to tweak the settings and go online everytime looking for help?

[C4D] General Discussion / Extremely Slow render times

« on: 2021-12-30, 16:28:13 »

Hi everyone,

I recently invested in a New Machine thinking it would help me work with Corona smoothly.
But I noticed some very slow render times on my recent render a very basic scene with a little amount of vegetation.
I have 55 trees and 500 grass models scatterred. The render is taking 10 hours with Cinema 4d and corona 7
Most textures used are between 6k and 4k.
I instanced everything except the house model. Render resolution 2560x1600. HDRI lighting only.

My Computer specs : Ryzen 7 3700x
                              32 GB RAM
                              RTX 3060
Before I jump into a GPU renderer. I wanted to see if the issue is coming from my ignorance or maybe Corona is specifically dedicated to rich 3d artists and enthusiasts who can only afford 38 cores CPU

The render and render settings are attached below

Thanks

[C4D] General Discussion / Apha 4.1 rendering process restart from scratch

« on: 2016-03-19, 13:01:25 »

Hi Folks I am having an issue with alpha 4.1, I created a small interior scene and let it render for 900 passes after the 900 passes, the rendering started again from zero, I thought it was an issue with R16, so I used the computer at work where R17 is installed, it did the same thing. Has anybody encountered the same issues? Is it a bug? or am I doing something wrong? I never had any issues with Alpha 3. I mainly use corona multipass, so I have to wait for all the passes to finish in order to get the openexr with different passes, when I stop the render  before I don't get the layers in the multipass. I am using C4D by the way.
ANy help would be appreciated...

[C4D] General Discussion / Is Corona for cinema 4d Slow because of its alpha stage?

« on: 2015-09-28, 21:09:20 »

Hi I have been trying to get a clean image using the scene provided by Thomas Vournazos, even after 45 minutes there is still noise.
Computer setup:
 i7 3930k @ 4 Ghz
 6 core 12 threads
 64 gig ram

So I was wondering if this problem is due to corona being in alpha stage, will it be fixed? I also noticed render times from other people on the facebook page above the 20 hours.
