An update of the Pixel Bender Toolkit is now available via the Adobe Updater and from the Pixel Bender Developer Connection area on If you have installed After Effects CS5, Flash Professional CS5 or one of the suites that includes these applications, you will see the update listed in the available updates. If you installed the Pixel Bender Toolkit via downloading it on from, you will need to download the update and install it by following the installation instructions.

The majority of effort in the release was on bug fixes found late in the CS5 development cycle. There have been some good bugs reported in the Pixel Bender forums, some are fixed in this release and some will be fixed in a later release.

There has been one major change in the behavior of the Flash preview in this release. In the 2.0 version of the Pixel Bender Toolkit, if you have a kernel with two inputs, the filter was treated as a Flash blend shader. This resulted in some unexpected results, especially when compared to CPU or GPU previews. Now, when you have a two input kernel, we instead create a ShaderJob and use the two input images as inputs. Hopefully, this will make things a bit more consistent. In a future version of the Toolkit, we plan to make this behavior selectable, but the blend case seemed to be very uncommon.

Thanks for using these tools and providing good feedback! If you find any problems or have feature requests, please post them to the Pixel Bender forums!

      This is a bug fix release only addressing bugs found late in the cycle. The only major change to functionality is the one I mentioned in my post.
