Candybar

My attempt to create a candybar. It’s based on a tutorial combining 3 fluid domains in blender.
Then I created the animation.

Issues I encountered (and still visible in Animation)
Unstable simulation
Holes in Mesh of fluid
Flickering
Artifacts
Tearing due to retiming.

I also wanted to use a nice sss-material for the caramel, but it crashed all the time rendering so I switched to an easier setup.

Comments and questions welcome.
