Summary
Summary Procedural vegetation editor, added in 5.7, works for skeletal mesh foliage generation and static mesh foliage generation. However, Non-Nanite static mesh generation is broken. As a result, any 3D Foliage generated using the new PVE plugin cannot be moved into another application and this is a significant production issue for making foliage using the new plugin.

What Type of Bug are you experiencing?

Steps to Reproduce
(1) Open UE latest version (5.7.4.) and install the procedural vegetation plugin, and also enable procedural vegetation/foliage in the project settings
(2) Install any of the Quixel Megaplant examples from Fab (e.g., Yoshino cherry)
(3 Option A) Open any of the skeletal mesh vegetation actors and click “Make static mesh” to generate a SM from the mesh
(3 Option B) A second option (also broken) is to open the PVE asset and, in the output node, change the file name and output type to static mesh for one of the tree types. Then Press Export to export a static mesh this way
(5) Right click > Disable Nanite on the new foliage static mesh
Expected Result
(1) Static mesh should work as normal
Observed Result
(1) Static mesh is completely broken; either has no leaves or all leaves replaced with simple triangles when Nanite is disabled.
Platform(s)
All platforms on both UE5.7.3 and UE5.7.4

Additional Notes
Images of all steps and the bugged result are attached. You can reproduce these results exactly from a new empty project with any of the Quixel Megaplant Procedural Vegetation Types. P.S. I already reported this using the official bug report tool in previous versions of UE5.7 but it was never added to the bug tracker that I can find and was not fixed when 5.7.4 was released.
