Material World Position Node undesired Offset in the Right Eye when using Instanced Stereo and Nanite

I’ve been testing out Lumen and Nanite in VR and I’ve encountered a weird behavior that I wanted to share in case anyone else encounters it.

After finishing setting up the project to use Ninite and Lumen I noticed that in the right eye the World Grid Material lines were out of offset on Nanite Meshes when Instanced Stereo was active

It also slightly moves when rotating the headset

I know that they are both features that shouldn’t be used in VR, hopefully it’s something that is going to be fixed with future releases
For now, the solutions I found are:

  1. Turn off Instanced Stereo
  2. Turn off Nanite on StaticMeshes that uses a material with the World Position node

I was testing with Quest 2 and Oculus Link
