Meshes are visible in editor, but disappear in Movie Render Queue render

I’m working in UE 5.3, using Lumen and Nanite, with lots of meshes and painted foliage.

Everything that can be has Nanite and Preserve Area enabled. The issue is that one of the kinds of foliage I’ve painted on the landscape (grass), and the buildings on the hillside behind are rendering fine, but many other meshes, including megascans rock formations, plants, and other elements from a mix of sources just won’t show up in renders. The two images in the comments show how the scene looks in the camera view in the editor, and then with the meshes missing in a Movie Render Queue render.

No other scenes in this environment have had this issue, so I don’t know what’s going on with this one. Everything is checked as “Visible”, and nothing is “Actor hidden in game”. Please help!

For anyone with this issue, here was my solution.

I had to disable Nanite for all hand-placed meshes, while enabling Nanite for meshes placed with the Foliage Tool. It made the scene run much more slowly, but the render is working now. :slight_smile:

Also, increasing r.nanite.maxnodes to a very high amount, like 12000000, and also r.nanite.maxvisibleclusters to a number slightly lower than the above helped keep things rendering.
