vvvv_45beta26\addonpack\modules\common\TextureFX
In the addonpack for Beta 26, there is this folder: TextureFX. All the patches that are in there look like modules, part of a bigger patch, I have not yet figured out what to do with them.
Seems some on has done a great job in creating/sharing some shaders, but for now it all remains a super secret mystery for me.
