01 Get Free Materials from Polyhaven and Fab to build Site Area

Summary: Converting 2D Plan into 3D Walkthrough in Unreal Engine 5.6 – Session 1

• ✅ Introduction & Objective

  • Kickstarted a new series on converting a 2D structural apartment plan into a 3D walkthrough for virtual film production.

• 📐 Site Setup

  • Used a 40ft × 60ft site (12.19m × 18.28m) as per the given plan.

  • Resources like houseplan_images.zip and apartment_set_01.zip were imported.

• 🧱 Project Initialization

  • Created a new Unreal Engine 5.6 project named apartment_set.

  • Set up environment lighting using the Environment Light Mixer (Skylight, Directional Light, Sky Atmosphere, etc.)

• 🌍 Creating Ground Plane

  • Modeled a large static mesh ground using Modeling Mode > Box (10,000cm × 10,000cm × 60cm).

  • Applied a custom ground material using 4K textures from PolyHaven.

• 🎨 Material Creation Basics

  • Created a material named ground, connected base color, displacement, normal, roughness, and specular maps.

  • Enabled Nanite Tessellation for realistic ground displacement.

• 📏 Plot Boundary Placement

  • Modeled and placed a site boundary mesh (SM_Site_Area) using plan dimensions.

  • Applied tiled material using a free asset from FAB plugin (e.g., hexagonal tiles).

  • Adjusted UVs with Unwrap and Transform UV for correct tiling scale.

• 🧱 Importing Prefabs from FAB

  • Installed FAB UE Plugin, downloaded free wall bundle (compound wall assets).

  • Imported 183 wall assets for use in the next phase (compound construction).
