Hi everyone, I'm currently going through Ben Watt's tutorial on advecting bubbles inside a geometry tutorial, and it's great. However, I'm stuck at the part where the bubbles inside the rubber toy is to be advected, and this is done using fluidsource's vectorfield. Ben glosses over this area of the tutorial, and I tried to download the project file, but the dropbox link is no longer valid.

Does anyone have this project file they can post? Or, could someone explain to me what he's doing around 10:30 mark of the tutorial video?

Thanks in advance.

From the facit node he generates reversed normals, then in the fluid source he creates velocity vectors from those normal vectors (“source attribute N”). Then he plugs that into the second input of the popnet and inside the popnet he uses advectByVolume and grabs the velocity from the second input (“Velocity source: second context geo”).

Hope that helps
