Object seems clipped - What happened?

Hi,
Suddenly one individual object seems clipped. I must have touched some setting unknowingly. What have I done? :no_mouth:

You may have changed/added the clipping plane. See the ClippingPlane command (or one of its siblings, like Enable/Disable ā€¦)

No, I tried that.

I wonder if it has to do with meshes having flipped normals. At first I thought that there were some ā€œrotation lockā€ on the object (see gif below) since the other objects seemed to rotate while this object only moved in position but no rotationā€¦ (Iā€™m not rotating anything though, just the perspective viewport as ususal).

But eventually I noticed thatā€¦um, Iā€™m actually looking ā€œthroughā€ the object, the backface that is, but not so with the other objects. Gives a spooky impressionā€¦, I have started to suspect that it is a backface visual phenomenon. I captured it before dumping it :

Made me dizzy for a whileā€¦ :slight_smile:

I see, you may need to RebuildMeshNormals or UnifyMeshNormals to get rid of this.
