GLOSSARY

G-Buffer

Image Filter and Image Layer events in Video Post can use masks that are based on graphics buffer (G-Buffer) channels instead of the more widely used RGB and alpha channels. Also, some kinds of Filter and Layer events can post-process objects or materials designated by the G-Buffer.

You can set two kinds of these channels in the scene itself, to identify and group objects or materials for a particular post-processing effect.

• You set an object’s G-Buffer Object Channel value to identify that object to receive a particular post-processing effect.
• You set a material’s Material Effects Channel value to identify that material to receive a particular post-processing effect.

You create object-specific or material-specific post-processing by going through the following overall steps:

Assign a particular Object Channel ID or Material Effects Channel ID to the objects or the materials you want to be post-processed.

In the Image Filter or Image Layer event, choose the channel ID that associates the event with the ID value you assigned in the scene.

When you execute the Video Post queue, the Filter or Layer event singles out objects or materials that have the designated ID, and performs its post-processing only on those objects or materials.
