What is causing this baking issue?

Spiderdance

So here is a baked model of a gun I just started texturing. I was starting out with some smart materials in substance painter and this weird bumpy/ripple effect showed up (even though it looked smooth before the material was placed on it.) What am I doing wrong?

The first image shows my low poly and the second shows my turbosmoothed highpoly. I'm still very new to highpoly modeling and baking, and I have found tutorials that teach about the basics of it, but apparently I am missing something pretty fundamental, so feel free to post links to tutorials.

Might be the resolution setting of your texture or of the texture set in your substance project. Try increasing the resolution (https://support.allegorithmic.com/documentation/display/SPDOC/TextureSet+Settings)
Also it seems like you use something with a generator in a layer that uses a curvature pass. Try turning different layers in the material on and off to see which one causes the problem.
Hope that helps as a first step.

its because your high poly has perfectly sharp edges. round em out!

Thank you for the responses. It was one of the layers causing an issue. Things so simple like this make me facepalm.. I really thought it had to do with the bake. Thanks!

I think it might also help to have your UV straight for thoses kind of vertical lines; it will avoid those kind of aliasing
