"Sawtoothing" with file -> blur -> heightmap

I am getting this “sawtooth” effect when importing a heightmap, applying a blur ( clean up ) and then applying a heightmap. It’s making it impossible to properly apply cliffs, they look just as bad as you could imagine. I’ve been wracking my brain for two days now on this, I’ve tried multiple revisions of the heightmap, I’ve “up and downed” all the settings imaginable, I’ve tried deleting and recreating the nodes, same idea.

I get a nahimic warning, but I closed out the service in task manager ( Nahimic.exe or whatever ) and then I didn’t get the warning so I am assuming that means it isn’t that.

Re: sawtooth

The reason for this is a fundamental limitation of 2.5d, the camera is projected top down the closer to 90° and angle gets from that the worse the reprojection gets.

You don’t typically want to be working with angles at 90° for a final shape.

You can use nodes like /distance node with invert input & output selected
Then process from there.

If you want to deep dive into 2.5d limitations check out this amazing live stream from my friend Cem.

It isn’t essential to remove this software, the Devs have done much work to try and combat it in general but it is quite an aggressive injection software that can affect software UIs.
