We are seeing the same problem in all of our products. Attached is an example from one of them whereby the grass texture polygons added in the 2020 product do not seem to be rendered in 2024.

MSFS2020:

fs2020_texture_poly
fs2020_texture_poly1920×1012 187 KB

MSFS2024:

fs2024_texture_poly
fs2024_texture_poly1920×1037 233 KB

This is happening with ALL materials, not just grass, and seems to also be unrelated to coloration or transparency parameters.
