I’m sure I’m missing something quite obvious and going right over my head. I’m trying to figure out how to place animated actors or animate existing actors before or after a character action in a level. Take for example the game Warframe - I have linked a few clips that show pretty much what I would like to accomplish. I have gone through resource after resource trying to find a solution or something to point me in the right direction, but I only end up getting to skeleton meshes and animated bones.
My thought is that the lids on chests or the doors on lockers, are separate ‘meshes’, and they activate a ‘timeline’ to adjust its ‘location’ after completing an ‘action’ - could this be the solution? I feel like there has to be something more dedicated to animation, being such a large part of level design…
