Richard Hurrey provides a simple solution on how to use Modo’s Order of Operations to create a spring Modo that appears under load in answer to a forum question on how a spring can be rigged in Modo and get the deformations and controls correct for animation.
This is an example for a user on the forums asking about how to rig a spring inside an AR15 magazine. Its using Order Of Operations (OOO) to deform a spring, and a top cap piece… then bend them both to give the movement a slight arc. The size, angle and position of the bend point a completely adjustable
Using a spring in a gun clip as an example, Richard set up the spring rig using a Renderable curve which will hold up under deformation (rather than geometry) and using a bend and a transform effector in a specific order and uses an item influence to control the top part of the spring.
