I’ve just tried the asset out after picking it up last week and I’m having an issue.
Tested this in my project and a new empty project.
Create landscape, create BP_GridManager_Hex. Align the two roughly. Place a BP_Unit_Anim on the grid. Play. Works OK
Same thing but sculpt the terrain a bit and enable… Procedural → Heighmap set to One Level. Does not work, the movement grid is offset and the guy wanders off the map when you click to move.
If I do the same test with square grid using BP_GridManager there are no problems. But I want a hex grid not a square one. So not really useful except to show that there seems to be a problem with the Hex version and not just a problem with what I am doing.
