Guys i have a question, can i realize animation for this drone, without “bones\joints” ?
I don’t think so. Without bones I don’t see there being any way to animate, but it looks like it has bones with those light green pyramid lines. If not, for this model I would create 3 bones. 1 bone is at the drone’s center of mass, the other 2 are in the center of the propellers. Link the propeller bones to the center bone which will be the root. When you rotate a propeller bone, it will rotate the propeller and make it spin and whenever you move the root center bone, it will move the entire drone which should be all the animation possibilities that you need.
