Shadow hinting

[Dutchbird]

Shadow hinting doesn't work. Are my settings wrong?
I am on a MacBook Pro M1 Max with Sequoia 15.17.1 and the latest Cinema4D.

Hi Dutchbird

M1 Max with 15.5 and 2026.0 produces this for me:

Only the active object is visible, but the Display Mode Gouraud is active (No Lines/Lines)

Is that the problem?

Here is the Maxon QuickTip, for anyone reading along.

(Sorry for the delay, this is my week off, and today was the Thanksgiving Holiday, which typically means a lot of traveling.)

Cheers

@Dr-Sassi No. This is my problem.
Maybe it has to do with settings somewhere.

Hi Dutchbird,

Yes, there are different encounters of it (not working, or artifacts, etc.); however, I am unable to figure out why it works on my M1 Max and not on yours.
I can get to a point where I get artifacts if I switch to a different rendering method or just change from move to rotate.
It is not stable, but the idea is to see a projection of the object below. So, please explore this workaround.

Here is the file:
CV4_2026_drs_25_MOsh_01.c4d
The idea is an RS Infinite Light, while set straight down (R.P -90º). The Editor View> Option> Shadow needs to be enabled.

If there is an object creating Shadow over that area you need to work with, drag it into the RS Infitinite Light> Project> Exclude.
Since you can switch the light off, you could create a view differnt ones for more complex scenes.

I hope that helps until a solution is provided.

Have a great weekend.
