I need to render a still image 27000 pixels wide. I can not find information on the maximum render size c4d can handle. There used to be a tiled camera preset but I can’t find it in R20
I tried to render the image at fill size but the render stalled. What can I do to get my final resolution?

Hi Geertjan,

The maximum render output is 128000 pixels, in one rendering.

(I checked as well in R20)

Anything below 30K will be handled by most file formats. However, I encourage to use PSB or Open EXR for large images.

As a side note: anything above 128K can be done (more often than not), using the shift parameter of the camera.

Let me know if there is anything else, I’m happy to look into it.

My best wishes for your project.

Thanx again Sassi. My render is with this maximum well within the limits. Does C4D keep the rendered pixels during rendering in RAM until it is completed or store the finished buckets to the harddrive to free RAM?.
With such large renders the final image is bigger than de amount of RAM I have in my MAC.

Hi Geertjan,

Typically you should be fine.

As usual, I like to have a practical base to answer, and not just parroting what I read.

Of course, I used the last hours to check out different scenarios. I even re-animated a ten-year-old computer with just 8GB, hence the long time to evaluate this. All machines I have checked worked just fine (30Kx30K, each 16bit/channel, or 32b/c., I consider for the production pipeline 8bit/channel as unusable, hence why I excluded it here.)

The used memory on my newest machine was bigger than the final file, in other words, the file size is not the way to determine what an ideal machine would need, there are many factors to consider.

In any case, the switch from RAM to any none SSD drive, as you know, will slow down dramatically the rendering.

All the best

I used the Mac> Activity Monitor to gain my data.

Thanx Sassi for the in depth research.

You’re very welcome, Geertjan, thanks for the reply.

Things change constantly, and that is certainly true for hard as well as software. So, it was indeed a great question to explore the current state again.

My best wishes for the project.
