Parts spazzing out when in each other

Hello!

I currently have a problem where when parts inside of another part spaz out when I move my camera:

How would I go about fixing this without unions?

Hi👋.

I don’t know if i’m right but you have to Union them all to fix the bug.

Whenever I use a union it causes the parts to have the same colour which I don’t want. How would I fix that?

Disable UsePartColor to fix that.

where would I find that? eeeeeeeeeeeeeee

Union’s properties, there’s a UsePartColor property or something like that. I’m sure you have it.

I disabled it but it still doesn’t work. The transparencies and colors still change. I want my model to not spaz out while still keeping its original form.

Are the parts in line with eachother (i.e. ending at the same point)? If so, scale the ones inside back by like .01 studs and they should simply appear as normal inside.
