I set up a fluid simulation using this tutorial: http://xedium3d.com/tutorials/fluid/ I know that this tutorial is for an older version of Blender, but the buttons and controls are still right there. I made sure to make my object an obstacle, but when I 'bake' the simulation, the liquid falls right through the object.
I have played with the variables a lot and tried pushing all of the buttons in different configurations.
I think that this is happening because my collision object is a plane that was sub-divided into a grid. How can i make the liquid flow across my grid rather than through it?
