The model was created in Zbrush and Maya and rendered with Arnold in Maya. A bones and muscle reference was used to built up the Hulk.
For the shading we used Arnold SSS Skin Shader with bump textures, displacements, color textures, and specular textures. The animation was done with Body Corrective Blend Shapes, Animated Displacements. The Facial System with Blendshape and Bones and Body dynamic simulation. The cloth was simulated and the Hair was created in Zbrush and Maya.
