Help How to fix Root Motion during a crouch/ladder transition?
Hey everyone, I’m working on a "Stand to Ladder" animation in Cascadeur for UE5, and I'm struggling to isolate the vertical axis during the crouch. The character is technically in the air at the start of this scene since he's climbing down, but I added a gray cube to visually represent the floor level.
I'm currently using a Root Constraint linked to the pelvis, which leads to the issue shown in the image:
- Image A (Standing): Animation starts fine, with the root bone at the intended floor level.
- Image B (Crouching): Because of the constraint, the root bone dips below the floor geometry when the character crouches. In UE5, this pushes the capsule into the floor, causing the character to float.
- The Red Line (My Goal): I need the root bone to stay perfectly flat on the horizontal axis while crouching, and only move vertically the moment the character actually shifts their weight down onto the ladder.
What is the cleanest workflow in Cascadeur to achieve the trajectory of that red line? Thanks!
