I changed an existing prefab (mirror on stand) to be a larger floor standing version. I saved it as a prefab from origin 0,0,0 and it appears fine in the prefab viewer etc. However, when i import it into my current map and rotate it, one part rotates the origin correctly but the other two still remain oriented in the XYZ direction and don't rotate accordingly. It means the tilting is at a crazy angle. How can i set the correct origin rotation on the two parts and make it stick? thank you.
