Just wanted to chime in that I’ve been following this thread with the hopes of getting some ideas for a non-matinee solution. The project we’re working on involves an NPC spiderbot (think of Rage’s little mech spider buddy) that we’d like to get running up and down walls, ceilings, boxes and other props, so the matinee-based solution wouldn’t really work in our case.
I did figure we’d want to build some sort of secondary collision mesh with little ramps around the base of objects the spider was supposed to climb up in order to get a smooth interpolation up the surface, but all the issues with gravity and sticking to walls/ceilings seems to be one of the biggest issues.
On an entirely separate note, can the AI navmesh system currently allow for navigation up walls and ceilings?
Cheers!
