create cube (white key) xyz size: 50,50,300 size → child under Cloner → Linear, count 12, xyz position: 58,0,0
duplciate the cube (black key), scale down a bit, move above the white key → drag it under cloner → untick Reset Coordinates in cloner object tab → reduce postion x to 28cm in cloner
apply black and white color materials on different cube layers
Create a Null (use to sepearate black white key in between), duplicate 2 white and 1 black layers, put them alternate under cloner, place the Null in between, like follow:
Copy the layers (3 whites, 2 black above the Null) and duplicate once more, place under most bottom within Cloner → Count of Cloner boost to 100
Animate the keyboard:
Apply Plain Effector on Cloner → Linear Falloff/field, position Y beginning 1500cm, ending 0cm
Add Delay effector on Cloner → Effector mode: Spring
Select all black key layers → Object →tick Fillet → radius 1.99cm, subdivsion 5 (give little round edge)
→ repeat the same fo white key layers
Create 2 thin cubes as a wall for reflection
Choose Physical render, go to Phsyical menu, turn on Depth of field, sampler: Fixed, sample subdivision 3
Apply camera → Physical → F-stop → 0.8 to 2 for shallow focus
