From licensee:
I’ve found an issue with the visualization of PlayerCollisions when using LandscapeSplineMesh with a mesh that has Nanite enabled. The Chaos collisions shown in the Chaos Visual Debugger are correct. It therefore seems to be an Editor issue where the deformation is not applied when Nanite is turned on. If I disable Nanite, the collisions are displayed correctly.
Is this a known issue? Will there be a fix in upcoming versions?
Steps to Reproduce
1) Create a new default Landscape.
2) Add some Landscape spline points.
3) Add a mesh with Nanite enabled to every landscape spline segment.
4) Enable "Player Collisions" view mode in the viewport.
There's no existing public thread on this issue, so head over to Questions & Answers just mention UE-356565 in the post.
