Target Color Correction to Camera

Ok, so this is more a C4D question than an Octane one. Hope anyone can help anyways.

I want to have my Color-correction Stuff in the corner of the view. So I thought that a Target node would do the trick, but it turns around and get tilted all the time and I can't make it turn the right way.

Anyone have an idea?

Hello,
I wish I could help but I am not a Cinema 4D user and it is indeed more Cinema 4D than Octane related.

However, I wanted to point out that this "color correction thingy" is commonly called a "Color Checker" (color rendition chart) and that there are many misconceptions about it.

To spare the details: it is not necessary in most cases. People often use it to give this "VFX Studio Breakdown" professional appearance on Artstation and similar digital creation websites.

It is also not an accurate "tool" for "color corrections" (which has to be defined as it is meaningless without a precise context) and the same applies in photography and cinematography (e.g. it is not purposed for sensor calibration).

If photo-realism is the goal, the need of a color checker has zero importance as opposed to the rest: surfacing, lighting, modeling "quality".

This tool is primarily used for plate neutralisation in e.g. VFX and not as an accurate mean or replacement of spectro-radiometer, monochromator, exposure/light/"color-meter" (e.g. Sekonic products) devices.

Thanks Elska, very good explaination.

I want to try to match my backplates and HDRIs (shoot with a Color Checker card from X-Rite), to see if I get better colors out of it.

Hi haffy,
what about placing the Color-correction Stuff as a child of the Camera, in the desired position/rotation?

ciao,
