Issue with running TTTE models (Visual Glitch)

Hello terchey! Good afternoon.

I am the creator of the TTTE models, you can find me on discord under the "cheddar1460" handle/username.
Yes, I eventually noticed that the Duck and Oliver models came with a few problems on them, they were a bit rushed due to time constraints, and because I really wanted to have a lineup of 10 engines done by the time of release, I am very sorry for the models being in a malfunctioning state, however I hope you got to enjoy the ones that work properly (which iirc correctly are all engines 1-7), I worked hard on them and I'm still very proud of creating them.

Alongside Duck and Oliver's problems, here's also a lot of little details about the models I didn't like and that I also plan to fix in the future.
The issue with Duck and Oliver are some weird parenting issue with the siderods and the engine body, happens a few times before, and it's related to Fragmotion.

I didn't get to fix them after releasing not only because 2023 has been a very busy year (that's also the reason I am very rarely active here when compared to last year) for me but also because I couldn't tell whether there was any public demand for more TTTE models.

By the end of the year I may consider releasing a "2.0" version of this pack, as of now I'm finishing up high school and will soon graduate. If there's some more interest for these models and creating content (track plans, more engines and wagons!) for them, I plan to make traincars, wagons, and a few buildings that can be used on layouts.

I am still looking forward for updates on "dad"s progress on making custom RTR animated models and DINOTICK's decomp (once in a while we discuss what has been done so far and there's still some work to do, but the project is still progressing!), I feel like that once these release more people will be interested in the game and it will also open a huge door in terms of possibilities for new models.
