Gimballing nozzle problems

[AngusJimiKeith]

I'm just beginning to delve into modding, so my knowledge on the subject isn't great, but I've run into an...interesting issue.

I have a gimballing engine (SRB, actually, if that makes a difference.) The nozzle is a separate mesh from the rest of the motor, and it is childed to my thrustTransform.

In game, it does rotate with control input. However, it appears to move the top of the nozzle, rather than the bottom, as if the bottom of the nozzle is the pivot point.

I've tried adding box colliders, moving the thrust transform and/or the nozzle's transform around, but nothing in Unity seems to be working. I don't know if this is a known KSP issue (I can't find it anywhere on here) or possibly something wrong with my model. Anyone have any insight?

These screenshots aren't great, but hopefully they illustrate what I mean. I might up the gimbal range to get more exaggerated screenshots if necessary.

The nozzle will pivot around its origin point / pivot point, so you'll need to edit that mesh in your 3d program so that the origin is aligned with the throat of your nozzle, or whatever point you want it to rotate around. Then you can move the object itself back to the proper place with respect to your engine, either in your 3d program, or in Unity.

Could this be an exporting (or importing) issue? In 3ds max, the nozzle's origin is at its throat, as is the pivot...when I import to unity, it's about 1/3 of the way down the nozzle.

Looks like it was either an import or export issue; reexported and started the Unity screen from scratch, nozzle is now behaving correctly. Thanks for your help!
