Detailed model of M2 Light tank (USA, interwar period).

This pack includes modules which allow to build version with one turret (12,7mm Browning, 7,62mm Browning armament), two turrets (same armamet in separate turrets) and version without turrets, which was used during Antarctic expedition in 1940-1941 years (USA base on Stonington Island). Extended tracks are also included - such tracks was used in Antarctic, but no photos or blueprints preserved, so these track modeled like Stug's 3 Ostketten. Model includes simple Continental R-670 engine.
Vertices: 2870 (one turret) +3787 (two turrets) + 461 (hatchway instead turrets) + 48845 (hull, wheels and engine) + 51728 (regular tracks) + 54060 (winter tracks) + 1458 (tools).
Faces: 2638 (one turret) +3619 (two turrets) + 428 (hatchway instead turrets) + 47907 (hull, wheels and engine) + 53424 (regular tracks) + 56180 (winter tracks) + 1496 (tools).
Pack includes three texture sets (Green, Orange and Rusty) with different materials resolutions:

• Hull (4k): AO, Color, Metallic, Normal, Opacity, Roughness
  
• Details (4k): AO, Color, Metallic, Normal, Roughness
  
• Turret (4k): AO, Color, Metallic, Normal, Opacity, Roughness
  
• Engine (1k):AO, Color, Metallic, Normal, Roughness. This material is same for all texutre sets except for Rust.
  
• Tracks (1k): Color, Metallic, Normal, Roughness
  
• Tools (2k): AO, Color, Metallic, Normal, Roughness. This material is same for all texutre sets.
  

Textures may be combined in any way (Rust and Orange textures for turrets are also included). Orange painting scheme is non-historical, real tank in Antarctic seems to be olive, based on the photos.
Substance Painter project for easu color change is included.
Blend file contains curves for easy track animation, origins of wheels and turrets are correct.
