☭ Clicking Massless doesn't change the mass

Hello there!

I have came to a problem where changing the Massless property doesn’t change the Mass:

For starters, this is what it’s supposed to do and is doing in older parts whose Massless property was set to true:

I don’t know where’s my problem so I can’t offer more information.

This is just because the part you’re enabling Massless on is the root part. Massless parts need to be attached to other parts that do have mass.

If the part is its own root part according to AssemblyRootPart, this will be ignored for that part, and it will still contribute mass and inertia to its assembly like a normal part. Parts that are massless should never become an assembly root part unless all other parts in the assembly are also massless.
