I want to model and animate a spring in blender. But my animation seems not to be compatible with unity.
What I tried so far:
Curve
- Created a curve and added volume to it
- Added a Bone
- Mapped the bone to the curve with Hooks
- Animated via key frames
The Problem with this is, that it works perfectly in blender, but unity just ignores the animation. You can see the bone, but the spring stays still.
Curve to mesh
- Created a curve and added volume to it
- Converted to mesh
- Added a Bone with parenting
- Animated via keyframes
The problem with this is that it distorts the thickness of the spring instead of just lowering the space between the rings. But the animation does import correctly to unity.
(Curve left, Curve to mesh right)
Is there any way to animate a spring like shape without distorting the mesh too much, which is compatible with the latest version of unity?
