If you use the Generate Normal or Bump Map filter in PS CC 2015, the resulting image will be unusable since it has a weave pattern through it. Run a cloud filter on an RGB image and then generate a normal map and you'll see it clearly.

Seen on OS X 10.10.5 and 10.11

What "weave pattern" are you referring to?

Did you install the Photoshop 2015.0.1 update?

yeah i just tried this and am seeing the weave pattern as well, its kinda like a interlaced video effect but in both the x(red channel) and y(green channel).

here is what ps i am on:
Adobe Photoshop Version: 2015.0.1 20150722.r.168 2015/07/22:23:59:59 CL 1032107 x64

i uploaded an image showing the issue, the left side is a crop of the original and the right is normal map filter run with default settings. original image size is 1024x1024.

the plugin itself itself looks like a vast improvement to the previous one, but this artifacting renders it useless in its current shape.

im running a gtx 980m with the most recent drivers btw.

Before CC 2015.0.0 (the plugin crashes photoshop now), I encountered the same problem.
My method : enlarge the original map (200%), apply the filter, then reduce the normal map (ok, it does not fit the problem, but it works properly)...

hey Chris. This is still an issue with 2015.1.2 – see the image below. It makes this feature unusable. I need to look around for a filter that works now.

OK, I can reproduce the artifacts (yuck). Looks like the 3D engineers overlooked something.

This issue should be fixed by the CC 2015.5 upgrade today: https://blogs.adobe.com/photoshop/2016/06/adobe-releases-major-photoshop-cc-update-today-and-announc...
