Help, such a problem. In 3dsmax, the animation works correctly, all the wheels spin as they should. But when exporting via datasmith, the animation works the same way, the body moves as it should, but the wheels jump anywhere. How can the problem be solved?

Using the "Link" making the high poly model a child of the dummy does not work when exporting to Unreal Engine via Datasmith. You need to make all parts be in the root level in 3ds max and then use "Link Constraint" in order to follow the dummy objects. Once this is done you are able to export over to unreal engine.

Maya
1. Select the 4-Wheeler wheel and then the target mesh
2. Go to Constrain menu and press Parent.

3. Redo for each part (or script)
4. Done

3ds Max
1. Select all the parts that are to follow the 4-wheelers wheel
2. From the Animation -> Constraints click on Link Constraint

3. Click the 4-Wheeler's wheel that the parts are to follow.
4. Done

Make sure that all the meshes are directly constrained to the 4-Wheeler Extended wheel meshes.

Like this
  • WheelMesh
    • tyre
    • rim
    • bolts
Not
  • WheelMesh
    • rim
      • tyre
      • bolts
