How to mirror objects in Twinmotion

Issue:

Twinmotion has a dedicated tool to move (translate), rotate and scale objects, but there is no tool to mirror (flip) imported geometry or Twinmotion objects.

Causes:

Twinmotion does not have any dedicated tool or functionality to mirror/flip geometry as the software is not designed primarily for editing geometry, however it still has a capability to mirror objects even though with some limitations.

Solution:

Even though there is no tool specifically made to do that, you can still mirror any imported geometry in Twinmotion using the transform panel.

To do this:

1. 1. 1. Select the object/geometry, or a container (folder) of objects/geometry you wish to mirror, then open the transform panel.
      2. Add a – (negative) sign to the scale value (red, green, or blue) depending on the axis you wish to flip the object along.

To reverse this, delete the – (negative) sign from the scale values in the transform panel.

Limitations:

1. With this method, you cannot mirror a copy of an object/geometry. To do that, you must create a duplicate first.
2. There is often a small graphics glitch right after an object/geometry has been flipped, making it appear as though it is now translucent, losing its materials/colors. It is temporary and is nothing much to worry about. Simply clicking on any other part of the scene besides the flipped object will restore the graphics.
3. This function does not allow you to mirror multiple selections. You can flip only one object or container (folder) at a time. If you need to mirror a group of objects/geometry, then create and move them into a common container (folder).

4. While it is possible to mirror/flip all imported geometry, not all Twinmotion object categories can be mirrored. Here is a list of Twinmotion object categories that can be mirrored:

Note: Using the transform panel to mirror/flip objects that have translators and rotators linked to them may break the links between the objects and the translators/rotators.
