Did you buy Bryce from Daz or does it say Corel when the splash screen opens up. There is a 5.0.1 update that takes care of a lot of metaball problems. It's still available from Corel FTP. The link I attached is for the windows English update. If you are using a MAC or want German or French menus back up to ftp://ftp.corel.com/pub/Bryce/5.0.1/ directory and navigate down into the menu you want. There are two files; Bryce5.01Update.exe updates the program, Bryce lightning is only necessary if you are using multiple networked computers to render.
