Collision dynamic not working on entire mesh

[Clara]

Hi everyone,

I have done an exercise where I have a bowling ball hitting some pins using collision dynamics.
As you can see in the screenshots, when the bowling ball hits the pins, the collision works as the ball affects the pins and the pins affect each other. However in the other screenshots you can see that the top part of the pins mesh don’t seem to be affected by collision as they cut/clip through the ball and one another.
Any ideas on how to fix this or what might be causing the collision to not affect the whole mesh?

Thanks

I think increasing the collision margin of the rigid body on balls/pins would fix that.

Another possibility is trying mesh collision, not Convex Hull.

Yepp, I was about to say. Mesh collisions follows your mesh more precisely whereas convex hull creates a collision grid around your object
