Studio backdrop and lighting Scene
Curved/Infinite Backdrop creation:
Method 1
Create a Plane, parent it over Bend → In Bend, Object Tag → Strength: 90 degree → Rotate Bend 90 degree (hold Shift)
→ Extend the backdrop by size up the Plane; smoothen the curve by increasing its W&H segments, or Bend Object → Size of Y axis
Method 2:
spline → Rectangle → Duplicate it, rename both as Small and Big respectively
Small: 10cm x10cm ;
Big: 2000cm x2000cm, tick Rounding, Radius: 300cm → make it editable → Choose Edge selection mode, delete half of the points and make the shape becoming like this:
In big rectangle spline tag → untick Close Spline
Add Sweep (in Extrude icon) parent over small rectangle layer, drag big rectangle between them:
Control size of the backdrop:
Adjust A) the Width and Height in Small Rectangle Object tag, B) Start/End Growth in Sweep Object tag
Remark: Don’t know why method 2 backdrop gives weaker lighting effect than method 1
Lighting:
1st, Global Light (i.e. just Light): Light → General: Tick Ambient illumination, intensity: 70%, position doesn’t matter
2nd, Key Light: Area Light → General: Shadow Area ; Details: tick Z Direction only (so only 1 direction has light, not 2) ; Intensity 120%
Optional (more real, make light intensity weaker when distance further) →
Falloff: Inverse Square (Physically Accurate)
3rd, Fill Light: Area Light (can duplicate from key light), Intensity 80%
