Hullo, I'm working on map that ideally I'd like to be playable in Odamex, but I'm having a problem: The map is pretty line intensive and - although I haven't surpassed what I took to be hard limits (there are currently around 30k lines and 58k sides, which will compress to 17k) if I try to open the map in Odamex it crashes immediately (to test, I tried deleting a particularly line intensive section, and then it opened fine). Notably, it only does this if I build the nodes with a nodebuilder other than Zennode; if I build the nodes with Zennode then it will run in Odamex, but there are large map-breaking HOMs everywhere (this is nothing to do with Odamex - it's the same in any other port). I'd like to use ZDBSP to build the nodes, since that doesn't generate the HOMs, but then the map immediately crashes Odamex :( Any advice here on what I'm doing wrong would be greatly appreciated. Thanks!

Brilliant, thanks! If I can help it, I'd rather not upload the map itself (it's a bit of an unfinished mess right now), but here's a map which replicates the behaviour:

This is a map that I made just to do some design work on some scenery, chunks of which I then copied into the proper map. It was after doing this that the problem started.

I've rebuilt the nodes of this one with ZDBSP (without any additional parameters) and Odamex crashes when it tries to open it, so I'm guessing it's the same problem.

Thanks again for your help :)

I see! Well, I'm pleased that you've been able to figure it out so quickly - thanks for taking the time :) I'd be lying if I said that I fully understand the diagnosis, but 'infinite loop' makes sense enough. So, pardon my ignorance, but is there something straightforward that I can do to make the map playable, whilst continuing to use ZDBSP? Or is it a deeper issue, either the nodebuilder or with Odamex?

Hmmm... It seems to open fine in the current stable versions of prboom+, Eternity, and ZDoom/Zandronum.

That's unusual! But if ZDBSP does it automatically then I guess that makes sense.
Off hand, I just rebuilt the nodes with both DeepBSP and glBSP, and the map still won't run with Odamex (though, the crash is a little different in each case).
I'm not sure if this muddies the waters further, or if this is what you'd expect. But if you like, I can post the versions with these different nodes also.

Good stuff - that must be the problem then.
Many thanks for your time, and for filing the feature request. I'd really like my stuff to be playable with Odamex, so I hope it's a feasible addition, and not too tiresome to implement.
Cheers! :)
