Project: Simple Spline Pipes (Blueprint-only)

Engine Version: Unreal Engine 5.8

Type: Procedural spline-based pipe Blueprint

Main Blueprint

• BP_SplinePipe — The primary actor that users place in your levels

• Features spline component for path definition

• Spline Mesh Components for pipe segments with optimized draw calls

• HISM (Hierarchical Instanced Static Mesh) for connection meshes

• Automatic UV tiling (maintains consistent texture density across varying segment lengths)

Meshes

• SM_PipeSpline — Spline Mesh Components: 768 triangles LOD0

• SM_PipeConnection — Connection/joint mesh (instanced via HISM): 128 triangles LOD0

Materials:
1 master material + 3 insances

• M_PipeSpline_Master — Base master material

• M_PipeSpline_Shared — Shared material variant

• M_PipeSpline_Tiled — Material Instance with UV tiling enabled (Static Switch Parameter)

• M_PipeConnector — Connection mesh material

Textures (packed ORM format)

• T_Pipe_Normal — Normal map

• T_Pipe_ORM — Combined Occlusion/Roughness/Metallic

• T_RustMask_RG — Rust mask (RG channels)

• T_PipeRust_Normal
