UE + Cinema 4D

when i work with static meshes it’s all fun and games (no pun intended)

but when it comes to skeletal meshes i have unlimited problems.

the main ones are:

if i rotate the scene at export, my characters/props/stuff import facing the floor.

if i rotate the scene pre-export, my ik’s/rigging/whatever technique i use gets broken because axis do not follow the parent object, but the world.

so, is there a method for using c4d for games production (that involve skeletal meshes)?
