A sci-fi container with some obviously dangerous matter inside, alien DNA perhaps, I have no idea, but I wouldn't touch. The base mesh was modelled in Blender with medium poly count, I'm using it in Unity with no problems. Quad topology with millimeter-sized triangles on bevels, every render engine will triangulate everything anyway. Materials and textures assigned in Blender, all attached in the zip file. Some previews are from Blender material preview, some from Unity renders (marked).
