LPub3D - Submodel not shown in main model

[Johann Eisner]

Yes. Characters with accents and diacritical marks are a problem, as for spaces are too as Philo points out.
Dots in file names other than the dot that separates the file extension (.dat, .ldr or .mpd) is to be avoided too. Use a - or _ instead.
Although that can give problems since the files LPub3D produces are often with a lot underscores too. I always use capital letters in a certain way to name files. I.e. FrontDoorLeft.ldr or something, rather than "left front door.ldr"
Also, very long paths can be a problem too. There was a time once the path (including the file name) exceded 255 characters crashes could occur too.
I could go on with warnings and exceptions...

Think it's just weird that it works in 2.2.1 and not in 2.3.6.
