Hello, I've got a problem with a sculpted object I bought on the SL Marketplace. The object in question consists of one sculpted prim. Upon rezzing, the object shows up as a sphere and never assumes its proper shape. Editing the object reveals that the sculpt texture does not display in the relevant field on the "Object" tab of the Edit dialog. Rather, the field says "Loading...", and the texture never actually loads. I have a copy of the sculpt texture in my Inventory (it came with the object). As such, I tried to apply a new sculpt texture by opening the texture chooser dialogue and selecting it from my list of textures; however, the relevant texture (along with others) does not show up. I also tried applying the texture as a sculpt texture by dragging it onto the sculpt texture field from my Inventory, but found that I was unable to drop it there. Applying other sculpt textures from my Inventory to the object worked fine in both cases. I also tried waiting for a while (several hours by now), rezzing new copies of the object, and creating new objects from scratch, setting their prim to "sculpted" and applying the sculpt texture from my Inventory there. None of this worked. Friends of mine have confirmed that the object does not show up as a proper sculpty for them, either: they only see a sphere, just like I do. One friend suggested cache issues, but I don't think cache issues could prevent the texture from e.g. showing up in the texture chooser dialogue. FWIW, I can open the sculpt texture in question and view it from my Inventory, the same way I would view any other (regular) texture. All other sculpties also continue to work fine for me. I'm running out of ideas here. Does anyone have any suggestions where the problem might lie or what I could do to fix it? I'm suspecting that the problem lies with SL's asset servers, which would put it outside my influence, but be that as it may, I bought this object and would like to use it. Thanks!
