[USER=“641905”]leo bar[/USER]: I’ve investigated the heightmap issue, and there seems that there was a problem with the new FindCloseValidOverlappingGridIndex function. On closer inspection how it was coded did not make sense in a lot of circumstances. I have altered the function to something that now seems to be working as intended. It is not the most elegant of functions, but it gets the job done. It might seem less efficient than it is, as the heavier parts of the function are unlikely to be checked often.
Replace the contents of FindCloseValidOverlappingGridIndex with these nodes to fix the heightmap issue. Let me know if you run into any issues with it. If not I will send another hotfix with this modification to Epic soon.
