Overview

Customizable M4-style rifle with 44 modular parts, 7 ready-made variants, and up to 20 skins, built and tested in Blender [4.2 and 5.2 ]. Everything is set up for Cycles.

What's in the download

• CUSTOMIZABLE M4.blend: the main scene with all parts and materials
• Textures/: PBR Metallic/Roughness maps (4K, 2K and 1K, depending on edition)
• LODs/: LOD0–LOD3 versions of every part (LOD0 only in Base)
• HighPoly/: high-poly meshes (Complete, Commercial Indie and Team/Studio)
• Substance/: Substance Painter project (Team/Studio only)

Quick start

1. Open the .blend file in Blender [4.2] or newer.
2. Customize the M4:  swap parts or attachments.
3. The .blend file uses the Black skin as its default material. You can change it to any other skin.
4. Switch to Rendered view or press F12 to render in Cycles.

Textures

Every part has its own texture set, exported from Substance Painter as PNG files with UDIM tiles (.1001, .1002, …). Blender loads the tiles automatically when the Image Texture node source is set to UDIM Tiles.

File naming: T__..png

Normal maps use the DirectX convention (green channel down). Blender expects OpenGL, so if you build your own materials, flip the green channel.

Skins

A skin is a complete set of the six maps above for every part. The .blend file uses the Black skin by default.

Base includes 5 skins at 2K. Complete Bundle, Commercial Indie, and Team/Studio include all 20 skins at 4K, 2K, and 1K.

LODs

Each part comes in LOD0–LOD3 (Base edition: LOD0 only). See the LOD table on the product page for triangle counts.
