Why pn earth would Adobe drop this hugely successful and uniqe set of plug-ins/filters! I know a lot of people are very unhappy about this. I really hope Adobe changes its mind and comes out with an upgrade/patch to fix this problem.
Thank you all for your interest in and enthusiasm for Pixel Bender. Pixel Bender has been offered in the past on Adobe Labs as a technology preview. As of CS6, we're no longer providing Pixel Bender as a Labs technology. Photoshop CS6 has taken the Pixel Bender filter most popular with customers, Oil Paint, and turned it into an official feature in CS6. Photoshop CS6 no longer supports Pixel Bender for 3rd party development.
