The p3d file include the mf file. I can see it in the list.
I found a similar problem (nested multifiles) David talked about the problem and to use ppackage but i didn’t find documentation about it.
Anyway, i just need to get a working folder with my app, i mean, the mf files, a generated exe and panda dlls and other dependencies. Is there any other (maybe manual) way to do that? its a desktop windows app.
