Recast graph and column

Hi, I am trying recast graph and cannot get the generated nav mesh to be closer to columns. The character radius is already small (set to 1).

Should I just use a smaller radius? My characters are normal humanoid size, so 1~ radius max, 2 units tall max~


This is indeed controlled by the character radius setting in the recast graph settings.
Make sure you also use a granular enough cell size, as otherwise it may be a bit conservative.
