Consider this platform made of RigidBody2D and PinJoint2D objects:

PinJoint2D setup is:

Softness = 0
Bias = 0.9

When I set the mass of the platform with high value, the structure starts to shake like this:

Why is this happening and how to fix that?

\$\begingroup\$ Here's a GDC Vault talk explaining some common physics quirks like this. Objects of very different masses tend to be much harder for joints to solve nicely. \$\endgroup\$

\$\begingroup\$ The Godot devs are working on a brand new, custom physics system for Godot, maybe it'll fix this issue. Here's the link to the progress report: godotengine.org/article/physics-progress-report-1 \$\endgroup\$
