How do I set the collision up for a general wall, it has pieces that are above the walk-able path i.e. a pillar, and because of this I can not access the wall unless I jump higher than the pillars, and thus walk above the main platform. I want the collision to only apply to the actual face of the mesh not like a huge box that covers everything.
In the Mesh view , in the Details panel, change the collision complexity to “Use Complex Collision as Simple” and the collision should adapt to your mesh form.
Thank you this solved it, as for AI Characters how would I do that collision? they have a collision box too, I want it to be for their standard shape but nothing dodgy.
