A pretty simple issue that I'm interested to see if anyone can reproduce and thus might be a bug. 3D soft bodies don't seem to work for Godot Server (headless) version. Should be easy to set-up and run a test -- happy to provide a code snippet if you need. My set-up is having a kinematic body interacting with a soft body. The kinematic body translates and deforms the soft body when rendered, but in headless mode, the soft body does not deform (but the kinematic body does update). The same behaviour happens for rigid bodies.
Thoughts?
