Custom Colt M4A1 assault rifle

Custom Colt M4A1 assault rifle Low-poly 3D model


The low-poly qualitative model Customized M4A1 assault rifle, created as close as possible to the original with exact dimensions. The model has high-quality PBR textures in 4k, also including textures for Unity and UE5 game engines. I create my models as realistic as possible. You won't see the magazine shaft , barrel, chamber or bolt , covered by the texture or geometry. If you even need to see the rifling in the barrel or any other small details of the weapon. Then this model is exactly for your project. Maximum manifold geometry in model. Open (non-manifold) geometry is only present in rare cases,but you will never see it even with any weapon animation and other manipulations. Game ready M4A1 Carbine for PBR game engines, renderers, first Person Shooters, VR games, and your other projects.

Textures and UV mapping info:

High resolution textures made for physically based rendering (PBR) shader system exported out of Substance Painter(7.1.1) as such required texture maps as:

  • Albedo(base color), NormalMap (OpenGL and DirectX), Roughness, Metalness, Ambient Occlusion, Opacity (for alpha reticle in scope), emissive (for reticle in scope) - .png / 8bit (normal - 16bit)

  • Unreal Engine (BaseColor, OcclusionRougnessMetall, Normal) - .png / 8bit

  • Unity (AlbedoTransparency, MetallicSmoothness, Normal) - .png / 8bit

Model unwrapping made on only 2 texture atlases. For better use of UV space, some inconspicuous parts that are on the other side, repeated small details have been unwrapped by overlapping (sides of the Handguards, stock, grips, etc.) Also Scale of inner unnoticeable parts decreased in UV space. That does not affect the quality of the textures and the general appearance of the model. The value of Texel Density: 64-65 pixels/cm (with 4k)!

  • M4A1_1 - 4096x4096

  • M4A1_2 - 4096x4096

  • Lense_Reticle - 256x256

Additionally, there are sets of textures without logos and engravings.

After importing the model and the textures into the target engine you have to follow the official engine documentation on how to set the material up!

All content of this model is packed into .rar archives, names of textures, formats, materials, etc. have the correct names. Folders and archives have very easy to understand names.Also for your comfort there are Readme files in every archive with the description of what this archive contains.

Are the parts printable with a 3d printer?
