This model includes detailed Kidney calcium oxalate stone (CaC2o4)
The model is based on real images of stone specimen. The entire geometry is very clean. It is all polygonal geometry with most quads. Everything is grouped and named correctly for easy selection and manipulation. It has enough poly definition for close-up shots.
The textures are 8k.
The lighting and render is done in maya 2011 using mental ray. All other formats include the geometry, default shaders and textures. The render is rock solid and it takes about 3-6 minutes per frame on i7-6700 machine (for the preview 1280x1280 image) which makes it usable for Animations. No Global Illumination or Final Gathering used. The renders from the preview are not edited in any way in post, so what you see is what you get.
