An excellent overview of the Lithtech: JupiterEx engine features can be found HERE: In brief, some pertinent features include: * True Dynamic Lighting - JupiterEx supports full dynamic lighting, with realtime shadow generation, realistic occlusion, glow effects, and diffuse/specular behavior. (Further details on the lighting system can be found on the Lighting page.) * Complex Shader Networks - The engine supports multichannel, numeric constant/tex mapped shading effects with support for diffuse/specular behavior, glow, translucency, bump mapping, simulated refraction, and more. * Physics - JupiterEx supports the following physics features: * Blended Ragdoll Physics - Ragdoll physics will blend from keyframed animations for more realistic transitions. * Simplified Collisi
