So I’ve got a background that should feature a river flowing downstage to upstage and then off to the right-hand side:
I’m wondering what the best way would be to animate that.
What I’ve come up with so far is:
- Draw the river as a tile-able rectangle that has some random floating leaves, sticks etc. on it,
- have the rectangle float from bottom to top straight up in a loop (like a conveyor belt)
- Use a “warp” layer to tilt that into the correct perspective
- Group the former two layers, call the result “RiverGroup”
- Put a shape below RiverGroup that has the exact form that the river should take
- set the Blend method of RiverGroup to to “Onto”
- Group all that.
This kind of works to the extent that I get an impression of a river that endlessly transports leaves and sticks from downstage to the big rocks.
But the river flows straight ahead onto the rock, as it were, and seems to go “underground” there. I’d rather have it start at the bottom flowing at an angle of around 30 °, and then gradually transport the sticks and leaves sideways in a curve out of the picture below the rocks, the way the red arrows run.
So I haven’t arrived yet. Any ideas on how to improve the approach? Do something entirely different instead to achieve the effect?
