Jagged displacement problems

(1/2) > >>

davetwo:
I'm trying to deboss some type onto a gloss surface, but I'm getting jagged edges rather than the smooth transition that I'm after.
The image i'm using is 4k, black and white, I've tried 16bit and 8 bit. Rgb and greyscale. Blurring the edges in Photoshop and blurring the edges in the C4D. But the artefacts are still there.

Am I missing something?

davetwo:
As an update, this seems to be a problem when it's applied to certain geometry. On a flat parametric plane the material displaces fine. But on the object I want to use, the displacement is jagged. Mmmm

romullus:
It wouldn't hurt to see some examples...

davetwo:
I have the same problem in a new file so - I'm resurrecting this thread.
I've tried testing on different surfaces and with different resolutions and profiles, but without any luck. Pretty crappy jagged displacement on all tests.
Am i missing something? or is this a bug?
Screengrab and test file attached.
Hopefully someone can shed some light on it.

(oh, Daily Build april 15. c4d r20, mac)

romullus:
Did you try to lower displacement size in render settings? It seems that you're using default settings, which might be too coarse for such fine displacement, especially in recent builds.
