If you have to use this software as a professional, you have your deadlines and you CANNOT accept bugs, that prevent you from working. If you go with Vue5I and it's unquestioned great features you're stuck and there is no way round. C4D, Maya and others may also have bugs, but not such generally blocking ones. So go into depth and solve the problem. Otherwise you lose a lot of customers, which lose their trust in your capabilty to provide a useful and productive peace of software.
