I've been reading posts for hours and can't find anything useful / current on whether:
1) It is possible to run any 64 bit Photoshop .8bf plugins with Gimp 2.10. The old pspi seems to only work with 32 bit plugins.
2) Specifically, is it possible to run the latest version of Alien Skin Eye Candy (V7)?
3) If 2) is not possible, are there any plugins that work in Gimp 2.10 that have similar chrome and brushed metal effects?

Thanks!

Don't believe so directly. Best bet is to use shellout and a surrogate program that can run 64-bit PS plugins. Not sure if XNView can even be used since you said it was a 64-bit plugin.
