When you configure Hippotizers Output Manager for SHAPE you will notice your Viewport Changes into a SHAPE viewport.

Enable: Use this to enable and disable shape. When disabled Hippotizer will act as if its a normal patch not a SHAPE patch.
Enable Network: This will toggle the SHAPE network on and off. If you cannot see a Hipotizer in SHAPES Network Manager this button might be off and need to be enabled.
Leave Network Group: This button will remove the Hippotizer from the SHAPE session.

Inputs: Inputs are Video Streams from Hippotizer to become available in SHAPE. Choose the Hippotizer Mix or Layer you want to send into SHAPE. In SHAPE use Input Manager to assign these to Materials to be applied to models or mappers.

Input 1 is always the mix you patched in output manager. If you want to use multiple mixes with SHAPE which is often the case simply add more mixes in Output Manager they do not need to be patched to SHAPE they only need to be assigned as an Inputs in the Viewport.
