An object inside in another object with physics properties - rigid body I am trying to create a physics simulation, but I not succeed...
What settings should I use for rigid body if I want to create an object inside in another object with physics properties (rigid body)

After I click on play the simulation goes wrong...

Now the bottle is intersecting or passing through one another ...
I have tried:

checked the normals
keep the real life proportions (size, weight...)
applied all transforms for scale, position and rotation
set Origin &gt; origin to geometry
increasing the Steps per second and Solver Iterations in the Rigid Body World settings (I tried with the maxima 1000 and 100)
set collision shape to Mesh and tried 0.4 or 0 as margins and source to final
For those who come here with this problem try setting the shape of the collision to mesh for the outside shape.

For your problem, I set the collision shape to convex hull for the inner bottle and it reacted normally. I don't know how attached you are to that setting but that might do it.
