The application of some filters can cause a group to be rasterized. When a group is rasterized, it is converted into a bitmap image. In 2D groups, the application of any filter causes rasterization. In 3D groups, the application of specific filters causes rasterization. For more information on rasterization and 3D groups, see Groups and rasterization.
The following filters force rasterization of 3D groups:
Circle Blur
Compound Blur

All Border filters force rasterization of 3D groups.
No color correction filters cause rasterization of 3D groups.
All Distortion filters force rasterization of 3D groups.
