In ShaderFX 2.0 we introduced real-time shadows to the Standard and SSS materials.

Now in 3.0, we introduce the Shadow Node. This new node allows you to insert real-time shadows into any (SM 3.0) material you create, including the Advanced Material, Glow and Fur.

The new node also gives far more control over the shadows, such as shadow color and strength.

In combination with the new lighting solutions we've added, this can create some really spectacular real-time lighting in your 3dsMax viewport.
