Hello! I just purchased the plugin and when trying to put it in the plug-in folder itself, I get this notification "The operation can’t be completed because “PixDither.plugin” needs to be downloaded." I'm not sure if it's an issue with the plugin or my computer itself. I'm using a Mac 26.6 and AE 2026.
Hello! Can you elaborate a bit more on the exact folder you are putting the unzipped "PixDither.plugin"? Is the operating system itself giving you this error message saying it needs to be downloaded? The website should just provide you with a "PixDither.plugin.zip" file that needs to be further extracted into "PixDither.plugin" which then should be put into the plugin folder "Applications/Adobe After Effects (version)/Plug-ins". After that it should just show up in the Effects panel in After Effects.
Looking up your error message in particular: it looks like a message that occurs in relation to iCloud/OneDrive services where the file itself is not actually fully resident on your computer and needs to be downloaded locally first onto your machine before being copied over.
