LPub3D - Submodel not shown in main model

[Jaco van der Molen]

Is this relevant?

Hmm, yes. I encoutered the same problems GREG998 describes there.
Some of them I could solve (by doing things a bit different), some not.

The ones that I could not solve, I start reporting to Trevor via Github.

I would agree that 2.3.6 is more stable than 2.3.7. So, Johann: try 2.3.6.

About installing/updating/uninstalling: I ran into trouble installing and updating it through the installer in Program Files.
This keeps settings in C:\Users\[username]\AppData\Roaming which does not turn out that well some times.

So since a while now I "install" as portable. Download the relevant Zip from here:
https://sourceforge.net/projects/lpub3d/files/2.3.6/
Then unpack in a LEGO folder or something.

This way settings are stored locally in the (sub)folder(s) where LPub3D is installed. And can easily be copied to the new version and one can have multiple version running.
Installing in Program Files, you cannot since settings are overwritten and seem not compatible all the time with versions.

I work on 3 laptops/PC's so on either machine I have the same setup:

C:\LEGO\LDraw\ (with library and stuff)
C:\LEGO\LDCad\
C:\LEGO\LPub3D\

That is all I need.

Next to that I do have C:\LEGO\LPub3D 2.3.6 and C:\LEGO\LPub3D 2.3.4.
This because files edited with 2.3.4 do strange things in 2.3.6 and 2.3.7 does strange things with 2.3.6 files.
