Bad Normal For Plane Errors

[ToxicHolyGrenade]

The story with this error is that whilst I am editing the Hopelessness 2 maps in order to crossover content from Half-Life: Absolute Zero, occasionally BSPGuy causes plane errors on the map I've edited, which caused the game to automatically disconnect, and when I try to type in the same map with this issue, it crashes the whole game.

What's going on?

No idea. I'd need the unedited bsp file and steps to reproduce the error.

Here is this unedited BSP file to use as an example.

Keep in mind, this problem occasionally happens, not all the time.

[wootguy]

Creating/editing/deleting BSP models and using the clean/optimize command might be corrupting the BSP. Changes that can be done with ripent should be safe.

What do you mean by BSP models, you mean NPC models?

Plus, it's the same with le2b from Life's End, and the Bad Normal For Plane errors are happening there too. But to be entirely honest, this has never happened to me before on BSPGuy version 3. I've edited monster_generic (the Kingpin and the Archers), , as well as changing some of the leeches to Archers, and that's about it, and I don't see how that is to affect the map.

Changing entity settings is "safe" and shouldn't affect plane data. There's a chance v4 fixes the problem but I still don't know how to reproduce this. That le2b map is loading fine for me in Sven Co-op.

Models that stored in the BSP file. They're used for entities like doors, elevators, and trigger areas.

I'm sorry, but as it turns out, le20 of Life's End, has the same errors, and this time its just the monstermakers I have edited. There is something definitely wrong.

To be honest, I am using XASH FWGS, and I don't remember this happening on regular XASH.

[wootguy]

Let me know if you figure out how to trigger the error. The map still loads for me after randomly editing keyvalues on the monstermakers.

[ToxicHolyGrenade]

Keep in mind, this is happening on XASH FWGS, not Sven Co-op. All I did, was edit one of the monstermakers that produce the Alien Slaves to Floaters, and the error just happens out of nowhere when I try to enter the map. And it crashes the whole game.

The worst part is, this "bad normal for plane" error has not been documented; there is nothing on how to fix this error and how to prevent it from occurring.

[wootguy]

I tried the same map in the latest Xash3D i386 build, and it still loads. Maybe the type of edit you did is important? Maybe a bug in the Xash version you're using? I could try your edited bsp and see if it still works.

That map loads for me. I needed to add a spawnpoint before Xash would let me do map le20 though. I made the edit using bspguy v3. le20_wootguy_edit.zip

Strange, it works. I think it has something to do with a coding bug in version 4 that's causing this. I hope version 5 is more polished, and with this bug getting finally fixed at that stage.

[ToxicHolyGrenade]

Okay, to update you on the issue, it might not be something to with BSPGuy after all, it has something to do with the XASH 3D FWGS engine. I tried the original XASH 3D engine, loaded map le20 that supposedly has the bad normal for plane errors, and it works.

[wootguy]

I can at least add a validation check for bad plane normals. If all of the normals are fine in the BSP then it probably is a Xash bug. Though it's still possible bspguy corrupted the bsp in such a way that only a specific version of Xash noticed.

[ToxicHolyGrenade]

What about the likes of BSPGuy Master? Does it need it too?

[wootguy]

yes, probably
