Hi Tal,

You could use GState tables. Take a look at the man pages
for pfGeoSet::setGStateIndex and pfChannel::setGStateTable
for more info.

Also note that you will need to create multiple
pfMPClipTexture objects, and assign each one to a different
pipe (see man pfuAddMPClipTextureToPipes).

Regards,
Paolo
