Um, not the same search function, is it? The Library is a module that Poser runs. This 'search' would be initiated by the main Poser program, I think. Library Search is manually initiated by us, and that is already opening up the web browser and going to Renderosity looking for stuff in PP 11.2 yeah I am thinking there are two different search functions. The problem I am having is that where .PMD files are being used, Poser isn't even opening ANY search function to find a missing or relocated one.
It definitely does want to find missing textures and morph delta's, but not .PMD files. And, PMD is a Poser native file type. SO I did set General Preferences>Library tab>File Search: to Deep. Tried it deliberately with a different PMD in a different Runtime, same thing. It doesn't even ask for missing files at all. It simply "falls through" ite execution of the PZ2 file and applies it. Nothing happens. Except the NAME of the dial now appears in the Settings tab for that Figure. But it is empty. I can correct the path manually and the PMD is then loaded and the dial now functions. But the Poser automatic search for the missing file isn't even called.
