Like 3DMax , Lightwave and even trueSpace , plug-in support creates unlimited potential without having to fully redo the software to a higer version. Instead of waiting for Bryce 5 we could already be using radiosity plugs and particle systems plugs to achieve the performance we all dream of. Doing this makes it easier for third parties to help create a stronger following by releasing their plug-ins for Bryce. I know sometimes I wish I had multiple windows to work in like Max and trueSpace which can be opened and closed around the main window.
