Realistic Horse model, polygonal, in OBJ, Maya 10 (mb and ma) and ZBrush formats in this download.
At the lowest resolution, the mesh is 1302 faces.
OBJ's of all resolutions are included, ranging from 1302 faces to 5K, 20K, 80K, and 600K. Textures are high resolution Tiff images and include diffuse, specular, transparency, and bump maps.
The mesh is fully UV-ied (non-overlapping) and completely clean and watertight, mostly quad/edge-loop based. The topology is good for skinning and deformation during animation.
