As far as I know, they are the same. I have KPT 3.03 for Photoshop and use them in Bryce. Haven't looked to see if there is a KPT for Bryce, I just intermix the photoshop version. If you put the plugin in Bryce, you will either need to change your plugin directory in Photoshop or reload the plugin to the plugin directory in PShop. Or, you can get Plugin Commander and try to merge with that tool. I'm curious about how you work this out.
