I modified one of the After Effects Sample Plugins and changed the category to "Color Correction". The plugin shows up in that category in After Effects, but NOT in Premiere Pro, there it shows up under "Sample Plugins" no matter what I put in the PiPL resource Category.
Does this remain as a problem for you? Have you contacted the plug-in manufacturer yet? Let us know what they say.
the sample plugin that I modified is from the Adobe SDK. And yes, it is still a problem, because I cannot release my plugin until I have solved this issue. I contacted Adobe support and just got the answer to reach out in this forum.
