Game Ready Asteroids 7 in 1 Collection Low-poly 3D model

This set includes seven unique and realisticly looking models of asteroids suitable for Unity or Unreal. The asteroids are all game/VR/AR ready low-poly models with 2K PBR-textures built to real-world scale (metric system). The asteroids vary a bit in size and form, but are all roughly 50 meters along their longest axis. The models and PBR-textures are prepared for use with Unity 5 and Unreal Engine 4, but can easily be adapted to other game engines, or to other uses. The models were created using Blender and Substance Painter. Preview images were rendered with Iray.

Polygon count
386 vertices (each)
384 faces (each)
768 triangles (each)

File formats
Autodesk FBX (.fbx)*
OBJ (.obj)
Collada (.dae)
3D Studio (.3ds)
Blender (.blend)
* There are three different FBX-files for each model, one standard PBR MetalRough, one for Unity and one for Unreal (the last two have triangulated faces).

Materials & textures
The models are UV-mapped and has a single material each. Each material has three sets of physics based textures, one for PBR MetalRough, one for Unity 5 (metallic workflow) and one for Unreal Engine 4. The textures are not baked into the model, but are saved as png-files with a resolution of 2048 x 2048 pixels (8 bits) in the zip-file PBR textures and the subfolders PBR textures, Unity 5 textures and Unreal Engine 4 textures:
