Discreet today announced that it is shipping Combustion 2.1, an update to its award-winning, unified paint, animation and 3D compositing software. Discreet is re-pricing Combustion, which was used to produce visual effects in films such as Star Trek Nemesis, Harry Potter and the Chamber of Secrets and The Lord of the Rings, to US$995 (previously $4,995). Version 2.1 is available for Mac OS 9 or higher and Mac OS X, and is offered as a free update for Combustion 2 customers. Discreet has also released Cleaner 6.0.1, a minor update to its popular video encoding software. Discreet will be showing both of the above products this week at Macworld Expo (booth #2125).
