Portal Animation

At some point it was mentioned that the ghosts should come into the room through a portal. I decided to research how to make a portal animation in blender.
I did a test animation to see how the ghost coming through the would look like.
Coffee cup animation
I thought I would be a cool idea if we had a coffee cup spill over when one of the Ghosts leaves the object,
so I modelled a coffee cup and animated it being knocked over.

I watched a YouTube video on fluid sim in blender to have the coffee spill out of the cup once it’s knocked over.
