Bleu - Just to add to Victoria's post, in case you run into other Bryce content, which will most likely be Bryce presets. Bryce presets are files that have extensions like .OBP (objects), .MAT (materials), .BSK (skies), .BRT (Deep Texture Editor ((DTE)) presets) and .BTO (tree presets). .OPB, .MAT and .BSK (the most common) are loaded by opening the appropriate Bryce Preset from the top pallette. .OBP from the little right pointing arrow next to the word Create; .MAT from the arrow next to Edit and .BSK from arrow next to Sky & Fog. In each case it opens a Preset window. At the bottom of each Preset window is an Import button which pops open a file selector where you can select the appropriate preset file. After OKing the dialog the presets will be added to the end of the current preset subcategory (may have to scroll down to see them). Once loaded the original preset download is no longer needed. Of course it's best to archive it somewhere. You'll also probably come across files that have extension like .OBJ, .3DS, .DXF, which are mesh based object formats that are be loaded via the FIle Menu item "Import Object". There may be associated image texture files that usually auto load with the file but are no longer needed after a correct load. And some content is Bryce scene files (.BR6/.BR6) which is loaded through the Open menu item. HTH; Dan
