This is a M4 Modular Kit I have put together with different parts for customisation. I might update some geometry/texture in the future. This was created in Blender through hardops/boxcutter/textools, with the plan to use it in Unreal afterwards. I aimed for a high level of detail on the gun and trying to keep a reasonable polycount (hopefully it should be between 30 and 50k tris dependings on setup used). Each part has its own texture set with different resolution depending on the mesh size (with the exceptions of the triggers that are contained within the body texture) for I hope better performance in game with limitting texture streaming, but keep in mind that the textures are still quite heavy. This is free to download and use, crediting is always very appreciated. Update: Added FBX.
