This right hand 3D model is made in Blender and rendered in Cycles. This model has quad based clean geometry, non overlapping UVs, it is textured rigged and animated.

It has clean topology of 2588 vertices and 2586 faces, all quads
The mesh, bones in the armature, materials, textures, lights and camera are all given appropriate names, instead of using the default names.

It is UV unwrapped with non overlapping UVs

Textures are in 4096 x 4096 resolution, PNG format that includes the following textures:
Albedo
Roughness
Specular
Displacement
Normal

The Displacement map is 16 bit, so the details will be clearly visible without any staircase artifacts.

The arm and hand has FK controls and the fingers have both IK an FK controls. The mesh is skinned and has corrective shape keys to get better deformations. The animations include fist animations, counting animations and a hand movement demo.

The model is exported in FBX and GLTF formats.
