BigCat is TWR’s proprietary software that produces the highest quality hair/fur for CGI animation. The system utilizes the most advanced technology and tools for modeling, styling, simulation and rendering. The built-in dynamics engine simulates the most complex hair behaviors and generates realistic results by adopting a physically based shader. BigCat is now available for Maya users and supports all major renderers including MentalRay, RenderMan, 3 Delight, V-ray and Arnald.
