How to make mp3 files from a montage

Thanks again for great explaining. I´ll try the render function. I dare say however, it is difficult to find your way around Wavelab complex as it is. There should really be some easy, more or less fool-proof, workflow strategies available, that would be a great help. It´s difficult to know what things like rendering does or not does to your material. I mean should you render your Audio montage or not? If you do, Should you then have to bypass master section or not when listening, not to get double effect treatment?
Can you erase the audio files in the audio files window once you´ve got them in the audio montage window and have added effects or edited them? There are so many questions it seems like a full time job just trying to learn Wavelab.
Yes, reading manuals seems hopeless some time all though you use them as encyclopedias which helps a lot generally.
Still I am keeping on hoping the day will come when I understand it fully….
