Try applying a 1-pixel vertical blur (directional or gaussian) in an adjustment layer above everything.

(and it’s moir

In addition to Steve’s advice, I thought it was worth mentioning that moire patterns generally result from scaling or moving things with a regular texture. Although the textbook example is a halftone newspaper photo, it can apply to anything with a regular repeating pattern including photos of grass, carpet, fencing, asphalt, etc etc. You generally notice it when you do subtle scales and moves, because the slight softening of sub-pixel positioning will emphasise different aspects of the texture as it moves between whole pixels and sub-pixels.

When you figure out what the problem layer is you can either blur it directly to lower the detail in the texture itself, or take Steve’s advice and blur with an adjustment layer. Steve’s advice is generally better, because it blurs after the layer has moved, while applying a blur directly to a moving layer will blur it before any transformations happen, and it’s the transformations which are causing the moire- so you may need more blur to get the same result. Don’t know if this makes sense, but I’ve got a few minutes to kill while rendering…

There’s another problem, not sure if it’s technically Moir

Thanks, that did it.
