Free Modular 3D Platformer Pack – Stylized Blocks Prototyping Pack ​

This free modular 3D tile pack is designed for quick prototyping of platformers, puzzle games, and block-based environments. Every asset is lightweight, stylized, and optimized using a shared color palette texture and unified materials to keep performance high and draw calls low.

Documentation ​

  • 10 Interactables – crate, key, coin, door, 2 buttons, ladder, lever, torch

Materials:

  • HJD_BuiltIn_Normal.mat – Single shared material for Built-in Render Pipeline
  • HJD_URP_Normal.mat – Single shared material for Universal Rendering pipeline (URP)

Textures:

  • HJD_ColorPal_Normal_01/02.png – 1024×1024 PNG (~3 KB) shared palette, 2 variations
  • HJD_Cloud00 – 1024×1024 PNG (decorative cloud with alpha)
  • HJD_SkyGradient – 1024×1536 PNG (vertical gradient background)

Scenes:

  • HJD_FP_ContentPreview – Full prefab overview
  • HJD_FP_SampleScene_01 – Sample demo scene

Editor Tools:

  • MyAssetWelcome.cs – opening Welcome Window with quick links to docs, support, and updates

Quick Start ​

  1. Open any Unity 2020.3+ project.
  2. Drag prefabs from Assets/HaniJahanDesign/FreePack/Prefabs into your scene.
  3. Apply the correct material based on your render pipeline:
    • URP – Use the HJD_URP_Normal material.
    • Built-in RP – Use the HJD_BuiltIn_Normal material.
  4. All tiles are pivot-centered and grid-aligned for easy snapping.

Technical Highlights ​

  • Models provided in .fbx format
  • Pivot-centered, grid-aligned geometry for easy snapping
  • Ultra low-poly (28–288 tris; most under 200)
    • Platforms: 28–52
    • Slopes/Bridges: 36–168
    • Hazards: 180–196
    • Interactables: Coin 116, Crate 188, Torch 261, Key 276, Lever 288
  • UVs: non-overlapping, packed for efficiency
  • Uses a single shared material and palette texture (2 variations)
  • Supports Built-in + URP (materials included)
