Oh, yes. Bryce 4 mats are absolutely importable into Bryce 5, no problem. And, yes the same thing from Bryce 5 to Bryce 5.5, yet if I remember right, you can ALSO go from B5.5 back to B5 if you want, the presets are cross compatible. Parts - Entire user file, imo. For (a Bryce 5.0) instance I will go to "Metal" catagory, select what ones I want, and all those will exported as ONE single .mat file, which holds all the various metal .mats (kinda confusing, but it works, trust me) AS
