Whenever I try to use both a normal map and a displacement map on the same material, it glitches out and looks weird. If I use just the normal map, it looks fine. If I use just the displacement map, it looks fine. Am I doing something wrong?

I need both because the normal map is providing fine detail and the displacement map is a more large scale surface adjustment.

Hi wrenthereaper,
normal+displ work well; attachments and screenshots for you to test.

Well, that's what I'm doing. I've attached a similar image with my results. Maybe I'm getting the normals settings wrong? I'm also running 3dsmax 2015 so I can't open your file.

Hi wrenthereaper,
here test scene 3dsMax 2015 made with Octane Render 3dsMax plugin 4.38
Let me hear from you.

Thanks for uploading that. So initially, I couldn't see the polygon lines in your project file. However, when I scaled up the layer, or reduced the displacement amount, the polygon lines began to show again. I've uploaded images of what I'm talking about. Interestingly, when I increased the number of subdivisions on the plane, the problem got worse.

The first image is the first image after opening the project file.
The second image is after reducing the displacement amount but not scale.
The third image is after increasing plane subdivisions.

Each quad is being split, and either the smoothing is glitching out or the UV is because the textures no longer align at each polygon intersection.

HI wrenthereaper,
What about Octane 3dsMax plugin are you using, version?

I'm using 3dsmax 2015 and Octane 3.03.3 - 4.16

Here's another example of what I'm talking about.

The first photo is just using the displacement map. The second photo I've attached the normal map node. You can see that suddenly the polygons are glitching out.

Hi wrenthereaper,
