Doom 64 EX maps have a limit of 18,000 lines?

P_LoadBlockMap: Bad blockmap - index >= numlines

This error message appeared in a Doom 64 EX map I'm working on. The only link on Google containing the error alluded to an 18,000 line limit being the culprit.

Any way around this? I had this massive, impressive and fun map that now can't be completed, probably due to an N64-related hardware limit.

If that port does not have an internal blockmap builder you are out of luck.

Could you go into detail, please?

The blockmap is more or less the collision map of the Doom engine, and one of the most strict limitations of the game.

If Doom 64 EX doesn't have an internal blockmap builder it means that it's limited to Vanilla levels of complexity with it, because it can't generate a larger one on the fly and it's limited to the one the blockmap builder of your nodebuilder generates.

Perhaps @zokum could help? Adapting his ZokumBSP to Doom64 EX levels might help push back the limit a bit since he worked on optimizing the blockmap as much as possible.

There hasn't been an update to either the engine or the editor in several years. Being that a D64 community is finally emerging, perhaps it's time to update?
