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.

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
Not

Hi, the trick I figured out is:
after all is done and the anim is baked you go to outliner and with right click enable shapes.
then delete the dummy shapes and export to UE4/5.
Important!!!!
All hires mashes have to be frozen before you parent it to the wheeler rig.

Hello! I created a car animation and I followed the Youtube instructions about selecting the wheel and using the Constraints > Link Constraint when setting up the car and the rig in 3DS Max 2022. I opened the Scene Explorer and the wheels and body are not under the rig mesh like the conventional rigging set-up. I exported to Datasmith and made sure to check Active Time Segment. I import the file into UE5 and my wheels are still grouped in one spot while the body still moves about the designated path. I'm not sure what steps I'm missing. Any help or advice is much appreciated.
Thanks!
Steve

Hi Steve,
Are you sure that all the parts are directly constrained to the dummy and are not nested with each other?

I was able to fix my issue. For some reason the problem continued until I restarted UE and then everything worked fine. Thanks!
