This model includes detailed and anatomically correct Human Respiratory System. The model includes Left and Right Lung, Trachea, Left and Right Bronchus as well as Bronchioles and Alveoli. The lungs can be visible as whole but each or both lungs can be hidden to reveal the bronchioles branches as well as alveoli inside.
The model is based on real images and anatomy books. The entire geometry is very clean. There is low poly version that is with level of smoothness on 3 for this render. If you press 1 you will get the low poly version.
The textures for Lungs and Trachea are 2k, for bronchioles 1k and for alveoli it is 512. There are total of 5 diffuse textures with bump map for each.
The lighting and render is done in maya 2011 using mental ray. All other formats include the geometry only and textures can be applied. Maya setup uses Sub Surface Scattering to get the flashy look. The render is rock solid and it takes about 5 minutes per frame on i5 machine (for the preview 1200x1200 image) which makes it VERY 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.
