Fake Fluid Effect

2

Base of the animation (use splice tool or use follow method):


Create Null → Coord. Keyframe XY position from 1st to 4th frame as follow:
0th: XY: 0,0
1th: XY: 100cm,0
2nd: XY: 100cm, 10cm
3rd: XY: 0,10cm
4th: XY: 0,20cm
(click keyframe record button on both X and Y every time at every frame)

Repeat the animation:

Show F-Curve
Click Position. X ( L side on Dope sheet) → Track (Position.X) menu appear at bottom R corner → After: Repeat; Repetitions: 5

Click Position.Y → After: Offset Repeat, Repetitions: 5

Create the 3d thickness liquid(cheese) into Spline


Select Null layer - >Mograph → Tracer → R click on Tracer layer → Current State to Object
Remark: The cursor on timeline is important, make sure it’s at 0F when add tracer, then at 26F or later (5 repetitions animation is finished when add Current State to Object)
→ can delete Tracer mograph once the Tracer spline is created
Rename spline layer as Zig Zag and on its layer → select Point mode → Select all point (Ctrl A) → R click: Chamfer
on any blank area in scene, drag mouse to smoothen the edges of the points (or adjust radius value in Chamfer menu)
In Extrude icon, add Sweep parent over Zig Zag layer
Add Spline Rectangle and properties set as follow:
width 10cm; height 80cm; tick Rounding; radius 1cm →
child Rectangle layer under Sweep, but above Zig Zag (not parenting)

Create the repeated animation:


Select Rectangle layer → Mograph → Matrix → Mode: Object → Drag Zig Zag layer in Object box; Count: 400; Distribution: Even
→ in Transform tag, reduce S (size) XYZ all to 0.3
→ Still in Matrix layer → add Cloner → Mode: Linear → Add Cube and child it under Cloner → Scale down cube to about 3cm (similar size to the matrix Zig Zag particles)
In Clone layer → Count: 400 (should be same as Matrix) → Position Y: 3cm (should let each cube almost touch to each other)
Select Cloner → Move up where the dispenser should start
→ Add Inheritance effector → tick Morph Motion Object →
→ Falloff → Linear Field → Direction -Y → Scale the field with narrower gap
→ put down the Cloner position that is closer to upper plane of the field
In Cloner → Transform → Keyframe position Y 0cm@0F to -1230cm@200F → Show F curve, make it linear

Converted the clones into animation spline:


Select Cloner layer → mograph → Tracer → Tracing mode: Connect all Objects
Drag Zig Zag layer out of Sweep layer (just put zig zag at most bottom layer), drag Tracer layer instead into Sweep (below rectangle)
in Tracer menu, Object → Type: B-Spline, Intermediate Points: Natural

Make the Dispenser on top move along with the cheese direction together:


In Cloner → Coord. Position X, keyframe 0cm@0F, -100cm@ 22F (22F is time when 1st layer of cheese is squeezed out) → Show F curve → choose Position X → Track menu (R side out of Dope sheet) → After: Oscillate; Repetitions: 11
Still in Cloner, add Delay effector → Effector tag, Mode: Blend
Set timeline to 220F for enough length
