Warning

This is an extension made by a community member and it only got through a light review by the GDevelop extension team. As such, we can't guarantee it meets all the quality standards of fully reviewed extensions.

Change 3D models proportions over time to make smooth animations like wobbling.

It's used in this example:

a 3D Bomberman-like game (open the project online)
