nanite visualization only shows black screen except a specific mesh, how to fix it ?

[exe.caliber]

I’m testing nanite and I realized that when I choose nanite visualization overdraw I can see nothing other than this roof tiles.
when I choose the mask option, everything is red except these roof tiles also.
trying other Maps doesn’t show anything.
these roof tiles are the only thing that is visible when I check the nanite visualization

nanite is enabled for the project and is enabled for other static meshes and I have direct x 12 as default

Hello there @exe.caliber!

A similar scenario was encountered in the following thread:

Nanite meshes only using Fallback meshes and not showing in visualization

In the project I’m workingon I had to enable nanite due to performance and this caused most of my models to only use the fallback mesh. Most models are also not showing up in the visualization view modes. [image] Some of my models are from quixel, these are mostly fine but the rest are either made by me or imported from Kitbash3D Cargo. All of these are very mixed, some works and some doesn’t. No matter what i set Position Precision, Normal Precision and Minimum Residency the models never sho…

The solution was to change the location of the derived data cache for both local and shared, then rebuild:

500×500 2.84 KB

I had the same issue and it wasn’t related to DX12 SM6 pr Material or Shader compatibility, it seems the project was stuck displaying the fallback mesh only. My Fix: Go into editor preference and change the location of the derived data cache for both local and shared, this will then ask you to restart, once it restarts it will force a rebuild of the shaders and meshes, this should fix the meshes being stuck in its fallback state.

If the issue persists, please test the following command, which resolved another nanite related issue:
