You got to be joking to try to use Blender for making games… Because its FBX pipeline is all screwy, it messes up the rigs bones when you import or export skeletons meshes into it, it skewers the armature bones when you export out to FBX and when you go onto the Skeleton Preview in Unreal from Montage the bone corruption Blender caused by skewing and rotating around the bones in the armature of the Skeleton that you get a deformed looking skeleton rig in unreal but it looks perfectly all normal in Blender until you look at location and rotation values and see they have been changed… Blender maybe free, but its FBX pipeline is messed up. It also has problems importing in skeleton meshes exported from 3ds MAX. Blender has issues with meshes that have bones it rotates the bones in the armature, , it even creates multiple root bones with the bone names.
is just not normal, its FBX code is not working properly with the Autodesk FBX code and making things go haywire… it even has some troubles with make Human rigs as well causing some twisting of limbs … It couldnt’ even import my doctor model properly and he was a FBX model with bones although when you put him through FBX viewer, his mesh and skeleton is all perfectly fine… On importing him, Blender gave him multiple root bones of his bone names that looked like porcupine spikes sticking out of his body and also threw his hair and eyes all down on the ground and supersized them. So I gave up on Blender with trying to get my FBX rigged meshes into Unreal because Blender couldn’t
import it correctly…
