Title: team render resolution
Post by: iamjens on 2020-11-17, 08:45:41

If i render via web interface with team render and server my output resolution are always 72dpi and not as set 300dpi.

dpi makes no difference to a 3D render. The only thing that counts are the pixel sizes of width and height. DPI is simply used by 2D programs to determine how the image prints (or is measured in real world units inside the 2D program).

EDIT - and you can change that value to whatever you like in your 2D program (just make sure "image resizing" is off, and you can set any dpi you like - not that it really affects anything, other than the "how the image size is measured in real world units in the 2D program")

@TomG:
It depends. When you assign a physical rendersize + DPI within Cinema 4D, the resulting render resolution is indeed DPI-dependent.
If TR assumes default 72dpi when a physical measurement is set, the render resolution becomes wrong.
However, this needs further information.
Like:
Is he using physical measurement in output?
Does this also apply to Standard-Renderer?
Does this only occur with TR?

But honestly, this smells more like a C4D-bug.

Indeed - I'd say the answer is never to use a physical render size, just figure out what pixels are required to meet the dimensions and dpi, and use a pixel size :)

By the way, the simplest workaround:
Set your desired physical size (e.g. 40x30cm)
Choose the desired DPI
Switch back to pixels.
Cinema automatically does the conversion for you.
