I have an object falling to the ground and breaking into pieces, but my plane, which is a passive rigid body, allows many pieces to pass through it:

In The Animation

Why is this happening and how can I fix it?

Planes are notoriously bad objects to use as solid collision objects. I would suggest to use a cube, with a cube bounding box.

You can add a collision margin on the plane (the passive rigid body).

Also, increasing the number of simulation steps per frame from the rigid body properties panel in Scene properties tab will give you better results.

    Increasing the number of steps did the trick (for a box), thanks! – Romuald Brunet Aug 11 '19 at 12:18
  • I encountered this in blender 3.2.2. The settings have moved to Properties > Scene tab > Rigid Body World > "Substeps per frame" and "Solver Iterations". For my usecase I had to increase them to 15 and 150 respectively to get clipping down to an acceptable level. – PLATO Aug 20 '22 at 18:07
  • @PLATO where the heck is this option?!?! Could you please share a screenshot? – mevsme Nov 18 '22 at 20:54

In the Rigid settings pannel, if you are using a plane or a cube, change the default Convex Hull in Collisions shape to box, so it simulates the collision of a cube
