Hi ascorbin, I see the point. Well in this case I strongly suggest you to google around for install_name_tooland see (e.g. here) how helpful it can be with regard to dylib handling. What I suggest is: make a backup copy of your dylib execute in a terminal install_name_tool -id "@loader_path/res/libs/osx/<yourlib>.dylib" <path to your c4d plugin>/res/libs/osx/<yourlib>.dylib rebuild your plugin to be sure that the referenced .dylib informs your plugins about the install name update This should update the install name of your dylib, inform your plugin about the path to look for and, in the end, have your plugin properly loading the dynamic library. Let me know, Riccardo.
