pathfinding:big navigation obstacles

I am making a character to avoid a building in a rts (modified top down example) However the character collide with the building but don’t change path .I did some tests with default prop (the chair prop)
I found out that when the chair was little/or a bit big character automatically avoided it but when i scaled it up big as a building .Char wasn’t able to avoid .And in most of cases the character get stucked running into the building…
Any ideas ?options to change in blueprint or? and thanks

Go into your Project Settings under Navigation Mesh and play with some of the generation sizes. Not sure which, but one of those settings should give you what you need.

ty.that work for the chair but not for my building mesh :confused: .Even when it is little ,charchter still cant avoid it
EDIT: idk what i did but it work now
