Hello, we are struggling with the message "nexus too small". Is there a way to raise the nexus for the entire game programatically? As written in the manual this only seems possible via the command line parameter nx.

The nexus is memory that you allocate beforehand. Allocating memory at runtime happens automatically, you need no programatical way for this.

Okay, let me describe a small scenario. We start the game without loading a level. The game comes up fine and stays alive until we load a level from a menu panel. Then it crashes during a level_load call and says "Nexus too small". Shouldn't memory then be allocated dynamically for this new level?

Yes. Crashes in your game are caused by a bug, not by the nexus. The memory structure can indeed affect how and when a crash happens, but it can normally not cause a crash.

DirectX 9 crashes when all memory is consumed, but that should not happen on a normal PC. Please find out what element of that level causes the crash - there are suggestions in the manual under "Troubleshooting" how to do that. If you can't find the reason, please post here again and I'll try to help.

Okay, I used a wrong wording. The game does not crash but the message "nexus too small" pops up during that ingame level_load call. Then I click okay, and the engine halts. When I use "-nx 100" as cmd line option, the level_load call works fine as well as the rest of the game.

The engine halts when you click ok? You mean it freezes and does not react anymore?

The application terminates after I click OK.

This is not supposed to happen. I've just tried it with a test level and it does not terminate. Are you using the latest version? If so, can you contact support and upload your level somewhere so that we can look into it?

It might also make sense to make the "Nexus" message a warning, not an error, so that you can disable it in development mode. In release mode it is disabled anyway as to my knowledge.

I don't know what you are talking about, as far as I can remember, the "nexus too small" message was ALWAYS an error that terminated the program as soon as you clicked OK.

Only in old versions. Since A7, when the nexus is to small, virtual memory is just allocated.
