PrimaryPart question

[WooleyWool (AWildWooleyWool)]

Does it matter what part is set as the primary part? I am going to have the model spin 360 degrees, but in order to do so, I need to set a primary part.

I’m assuming no based on its description:

Note when assigning the PrimaryPart that the part must be a BasePart that is descendant of the Model. If this is not the case, the PrimaryPart will be set to nil in Roblox studio, or produce an error if done so by a Script.

Yes, the primary part will matter,

All other parts in the model will also be moved and will maintain their orientation and offset respective to the Model.PrimaryPart.

At least for SetPrimaryPartCFrame usage.

So, if I set a random part in the model as the primary part, it’ll cause issues? Will adding an invisible part, welded to the parts, fix the issue?

If you’re using a function like SetPrimaryPartCFrame, there will likely be a difference when selecting random parts.

An invisible welded part works for your case.

That’s also another alternative I have planned. Thank you!
