The filter is set to None in the tests, but I tried it with the radius from 0 to 15 (and all the resolutions), and these "edge artifacts" are still there.grimm wrote:Do you have the blur filter turned on? I can see some of these artifacts when I turn it on, but looks good when turned off.
Please rollback the Displacement node back to old version

Hmm, not sure then what the issue is? I have tried both tiled and non-tiled displacement maps, 8-bit and 16-bit versions, simple and view projected UV unwrapping, and still do not have those artifacts. The only time I can see some problems is when I turn on the filter. Could it be an OS issue, I'm running Linux Mint 19?

Just wanted to add, if anyone has a displacement map they would like me to test, I wouldn't have any problems testing it.

Yarrg! I didn't even notice that, downloading it and checking it out.ChrisH wrote: You're welcome to download my test scene (above), the texture is packed into the file.
I definitely see the issue now, it looks like Octane is going past the edge or wrapping the edges around? I double checked my displacement tests and can see some of the same issues, they are just harder to see. I also brought your image into Krita and took a look at it. I didn't see anything wrong with it, although Krita did load it as a 8-bit image. I converted it to 16-bit, but it didn't make any difference. Looks like a bug to me.Linux Mint 21.3 x64 | Nvidia GTX 980 4GB (displays) RTX 2070 8GB| Intel I7 5820K 3.8 Ghz | 32Gb Memory | Nvidia Driver 535.171
There is one more filter.
The artifacts are caused by bilinear interpolation between pixels on the opposite edges of the texture because it's being tiled. And tiling can not be disabled (currently).
Notice the gray edges:
Here is the 5x5 pixel map. There was a big discussion about this in the C4D forum too.
I hope this makes sense.
