Please note these files are provided for customers who have already bought one of our shader preset packs, but have now purchased Studio 3 Advanced, and would prefer to use the UberSurface shader instead of the HSS. The zip files contain -only- the .ds files and are useless unless you've already bought the product concerned. The folder name remains unchaged, and so if you wish to keep the original HSS versions of the files, you'll need to rename the folder to something like 'Ancient TechDS_Uber'. In the future will will be offering our shader presets in both versions, for those with HSS or those with Studio3 Advanced. Please bear with me as I continue to update this list.
