Tutorial 13: Blooming Flower

Step 1

Create five slider variables

Add five Set Variable blocks at the top of your Path Group, each with Show in Viewport enabled:

• petalCount = 6 — number of petals

Step 2

Center the flower on the bed

After the variables, add a Translate block with X = Bed Size X / 2 and Y = Bed Size Y / 2.

Step 3

Stack layers for the flower height

Inside the Translate body, add Stack Layers with Start Z = Layer Height, End Z = flowerHeight, Layer Height = Layer Height.

Step 4

Scale from bud to full bloom

Inside the Stack Layers body, add a Scale block. For both SX and SY, use a Map Range block: Input = normZ, In Min = 0, In Max = 1, Out Min = 0.3, Out Max = 1. This scales the entire flower from 30% at the base to 100% at the top — the bloom effect.

Step 5

Arrange petals in a ring

Inside the Scale body, add a Polar Array with Count = petalCount, Center X = 0, Center Y = 0, Radius = arrayRadius. This distributes copies of whatever is inside evenly around a circle.

Step 6

Twist petals as they rise

Inside the Polar Array body, add a Rotate block. For the Angle, build: normZ × bloomTwist using an Arithmetic (×) block with Variable (normZ) on the left and Get Variable (bloomTwist) on the right. Each layer rotates a bit more than the last.

Step 7

Create star-shaped petals

Inside the Rotate body, add a Star block with Points = 5, Outer Radius = petalSize, Inner Radius = petalSize × 0.4 (use an Arithmetic (×) block with Get Variable (petalSize) and Number (0.4)).
