Hello all, greetings.
I’m creating a F1 car sequence driving on a race track. I’m running into issues, but I figured out how to make the wheels spin with my custom model of a F1 car loaded unto a custom path.
For curious minds:
- Import your model
- Create rotators for the wheels
- Save that model along with it’s rotators (best to parent them) to your custom library
- Drag n drop that custom library model (which will also have the rotators intact) into the object placement window of your custom path. By default it’s a simple cube.
Bingo, you now have a custom car model with spinning wheels running along your track! You’ll have to play with the balance of spinning wheels to moving along the path ratio.
Another tip is if you need to have the wheels spin faster than a value of 10, you can copy and paste rotators and parent them together to get multiple values of 10. It’s a lame workaround that devs could easily fix by allowing a value more than 10, but there you have it anyway. You’ll need to do this step BEFORE you save the model, and it’s rotators to your custom library. Again, come on devs. You’re really making the user work for this, aren’t you? 
NOTE: You cannot add an imported object with embedded animation to your user library. Argh.
Now, finally, my question:
How do I parent my sequencer camera (or pick it’s target) for an object on a custom path? Since that object doesn’t show up in your Scene Tree, then how? HOW???
My suspicion is it’s not possible. But before I explore other options I want to confirm that it’s not user error, first.
I’m thinking I need to move over to Datasmith/Unreal. Would love to avoid that if I could. I love the streamline and intuitive nature of Twinmotion. I just don’t love it’s particular user cliffs, and oversights, however.
