The specific crane model we needed to rig was the Supertechno 50+ (Supertechno 50), which had previously been rigged in another digital content creation tool.
Our task was to recreate the control rig within Unreal Engine 5 to meet our techvis requirements.
The main challenge lay in creating an extendable arm control rig that mimicked the behavior of a piston along a single axis, rather than a simple IK chain.
To tackle this, I turned to an insightful video by xxerbexx, which provided valuable insights into the mechanics we needed to replicate.
The Slide Chain node proved to be the missing piece of the puzzle, allowing us to achieve the desired functionality.
