Cast Reflections
The Cast Reflections property for RPC objects works differently than a similar setting in Autodesk
®
Max . RPC content provides a specialized texture that is applied to a flat plane. When the texture is applied
to the opposite side of the plane, unusual reflections can result. The Cast Reflections property for RPC content
produces a more realistic result.
When you turn on Cast Reflections, the object includes a second plane that faces away from the camera.
This plane shows the image of the opposite side of the RPC object. The reflection is accurate only when the
RPC object is directly between the camera and the reflective surface. As the reflective surface moves to a
more acute angle, the reflection thins.
The Cast Reflections property can significantly increase memory requirements and render time. Use this
property only when the RPC content should cast a reflection on a vertical surface directly behind it. RPC
trees (and other plants) may not require this property turned on, even when a reflection is expected, because
the front of a tree closely resembles the back.

Creating an Entourage Family

You can create an entourage family that does not use RPC content for render appearances. For example, if
you have already used AutoCAD or other design software to create a render appearance for the object, use
the following procedure.
NOTE To create a Revit family for entourage that uses RPC content for render appearances, see
Family on page 1143.

Description
Whether to control the transition between frames in a walkthrough. Use this option
when the camera is relatively close to the RPC content or is moving slowly around it,
or both. This option results in a smoother appearance during a walkthrough. However,
it may cause the RPC content to be blurry in still images. When this option is turned
off, you may notice small image jumps or ticks in a walkthrough.
This property applies to RPC content in rendered walkthroughs only. See
Views on page 116.
Whether to lock the RPC content to a fixed image. As the camera revolves around the
RPC content in a walkthrough, the image is not updated but continues to face the
active camera. This option can greatly reduce RAM and render time required during
the rendering process.
This property applies to RPC content in rendered walkthroughs only. See
Views on page 116.
