I have just built a new pc, and have installed an nvme drive, letting my old c drive be a storage drive,(daz is on my g drive), I have installed daz studio 4.12 onto the new machine and copied across my settings that were stored in the users folder on the c:drive, everything works fine, except when I go into the surfaces tab and select presets there is nothing there, I have no idea how to get them back? any ideas on where they have gone, as I can not set an iray uber shader.

Getting old and still making "art" without soiling myself, now that's success.

So the other Presets tabs, and the Categories and Products lists, are populated - just not the Surfaces presets? Can you find the presets in, for example, the Products lists (Smart Content tab or container in the Content Library) for Default Resources? Also, is the Filter By Context box checked in the Presets tab of the Surfaces pane?
