getting this error and it sbugging me i really want to make a map but this error wont let me

That error can be from a few things from bad geometry, low memory, light outside your skybox ect.

Did a script placer map without any edits compile originally?

idk im new to making maps so this is kinda confusing
i watched a video on it and its not running the map after it compiles like it should so i have been looking this up all morning

i use the ugx script placer

Make sure the option "run after compile" is not checked when compiling.
