Houdini Tutorial: Use the Matrix | How To Extract And Use The Transformation Matrix (COMPLETE WAY)

Using the transformation matrix of objects in Houdini is one of the main techniques when it comes to manipulating objects at the origin, whether it's on animated meshes or scattered objects around your scene. Once you understand the concept, you can easily project your objects and meshes to the origin, make your changes, and send them back to their original positions. In this short tutorial, I will show you the complete method do that.

the Straighten node is useful to unrotate an object, and can store the xform to restore it later
