SprayPaint

Wall Graffiti Simulation

---

Anti-latency project in Unreal Engine

• Unreal Engine 4.25.4 (Cartoon WIP - Round2, Anti-latency 2.1.0)
• Unreal Engine 4.26.2 (Round3, Anti-latency 3.1.0)

*** NOTE: ***

-If WallBP gets recompiled or spray size doesn't scale by distance, Paint MID Ref will have to be recopied from WallBP in hierarchy to the VRPawn paint reference.

Non Anti-Latency Controls:

• WASD: Move Paint Can
• Space: Clear Canvas
• K: Switch Camera Used
• L: Get Spray Size
• Colors:
  • 1: Blue
  • 2: Red
  • 3: Green
  • 4: Yellow
  • E: Random
• P: Get Paint Thickness/Stored Color from Heat Map (works in later versions)
• R: Get Camera Rotation from Wall

Project Iterations

(with and without anti-latency)

---

Cartoony Spray Paint Project (spray map):

• Speckled Conrete wall
• Colors: Blue, Red, Green, Yellow, Random
• Paint Drip is a fade-in decal
• Distance from wall origin changes paint spray size
• (Anti-latency version available)

Spray Paint Project Round 1: Added Heat Map (HeatmapSpray map)

• Speckled Conrete wall
• Colors: Blue, Red, Green, Yellow, Random
• Paint Drip is a fade-in decal
• Distance from wall origin changes paint spray size
• Build up of paint is stored in heat map (second render texture + material)

Spray Paint Project Round 2: (HeatmapSpray map)

• Speckled Conrete wall
• Colors: Blue, Red, Green, Yellow, Random
• Paint Drip particles WIP
• Build up of paint is stored in heat map (second render texture + material)

Realistic Spray Paint Project Round 3: UE4.26 (HeatmapSpray map)

• Cobblestone curved wall
• Colors: Blue, Red, Green, Yellow, Random
• Working Paint Drip, testing Niagara (Niagara particles don't draw to RT)
• Build up of paint is stored in heat map with size
• Working camera mimic for heat map
• Gets color from heat map for drip
• antilatency not implemented but installled
• Organized BP
• ColorCollider boxes to change paint color w/o keys

---

In Progress:

• Niagara particles drawing to render texture?
• Antilatency w/ new version
