Hi @Boris
I used it here as you suggested. I know the other topic was for 2020 ported content. But, I decided to just make a native 2024 version of that airport. I noticed the rectangle with exclude buildings wasn’t working. So I used exclusion rectangle (exclude all) along with a polygon. I had different behaviors/results:
RED - I added an exclusion rectangle along with a polygon and the autogen models were still visible in the editor. Once the package is built and placed in community, buildings are not there.
YELLOW - I used exclusion rectangle and it took care of a large autogen building, but there was a smaller one hiding under it. It went away with a polygon. Those changes were visible in the editor.
PURPLE - There is a line of trees that I could not eliminate. I used the polygon with 0% vegetation. I tried a couple more things with no success. I left the polygon hoping it is a bug and these will eventually disappear.
This is all with SKPA for MSFS 2024. I uploaded it last weekend to the MCP. If you don’t have access to it yet, you can probably replicate the behaviors in a new project.
I used a screenshot of Bing maps from my phone as I’m away from my computer.
