I thought about installing my own folders (i.e. "Architectural") into Bryces preset section - but there is one section labelled content - but another entirely different one labelled presets. I really didn't have a step by step procedure for that that I could trust.

Also - I have no way of previewing mats, skies, etc. BEFORE I install them. My collection total is probably around 4000 presets altogether and growing. I wish there was an app that allowed you to actually see what a preset is before you load it since I have terrains with names like "Coffe and Cream" and metals with names like "Candy Shine" - and skies with names like "Tangerine Dreams" - it's really hard to tell what you have before you put it in Bryce.

I seperated them once into BRYCE CATEGORIES (Terrains, Waters, etc...) And found that I had terrains mixed in with my miscellanious mats and glasses mixed in with waters and liquids because I couldn't preview the stuff first.
