I made a weapon that can be used to detect phantom BSPs. All you have to do is run around the map while holding fire. It works a lot better if you remove all scenery, vehicles and weapons from the map (you can just make a copy of the scenario and remove stuff quickly in guerilla).
Edit: I totally forgot about command "object_destroy_all", you don't have to remove anything manually just enter that command ingame.

Phantom BSP found on carousel.

Let me know if there are any issues.

Turn spooky phantom bsps into pink fluffy clouds!

triggered

This looks awsome! Can you tell us more about what you learned when making this? What material type do phantom bsps fall under?

Phantom BSPs use the same material as the triangle of the BSP that caused it. The only thing I learned is that particles (just like any other object) can't be spawned inside the BSP and I used that to create this weapon (because particles can get spawned under phantom BSP).

Excellent, finaly I will be able to fix Hex Zone.

Looks cool and all, but what about big maps? Seems like just using the command to find them would be a lot easier in that case.

You can debug phantom bsp's in sapien altis.........

Yeah it's not efficient in large maps. Using the command is not exactly efficient either ¯\_(ツ)_/¯


Oh wow, what else do I not know? Tell me more!

Sure, sure.

The guy who made bigass employed a feature which allows you to change your biped.

:O

10/10.

Great stuff altis. This is very useful.

You can also turn off gravity in sapien in the tool window and drag objects along their local axises.

You can teleport using the command "cheat_teleport_to_camera"

You can move objects by holding shift/caps lock and arrow keys. You can rotate them by holding ctrl and arrow keys. And you can change the model of the pivot thing to be less annoying:

aLTis you're a pimp. Thanks

Did you know that maximum fog density doesn't render anything that's completely fogged?

Altis has 99 problems and those bad unwraps in bigass ain't one.

Turns out I'll have to reexport bigass day bsp so I could fix stuff while I'm at it.

Oh my god he might actually listen to my suggestion for once.







Fix the trees too while you are at it.

Is a method used by ancient consoles, like the N64,

For example there´s Turok 2: Seeds of Evil

aLTis do you think there's a way to detect other geometry errors like surfaces where nades/projectiles go through? Can't remember if we talked about this. There's a couple spots in vanilla Halo PC Derelict that have those holes. There's a spot on the beach in No Remorse as well.

Make a weapon which chain spawns grenades everytime a projectile is fired.

Set biped health to 50x and speed to 10x.

Run around your map and pay attention when something doesn't explode.

Aside from that usually acting upon all of the errors and warnings tool spews out and debugging your structure in sapien using "collision_debug_phantom_bsp 1" e.t.c should amend nearly all glitches.

That would be harder to spot. The same weapon can be modified to create particles every time it hits a collision, then only places that don't have those particles would have collision errors. But that would probably be as effective as running around the map with infinite ammo and shooting everywhere, I can't think of a better way at the moment.

Most of the time these holes are related to having two separately sealed elements that intersect in the bsp. When it is this type of situation tool outputs a warning. I know of a hole in highground that is not this situation, and currently have not found a solution to the problem. I'm guessing it may be from having extremely small triangles or triangles that are nearly linear. Has anyone experienced one of these holes that was being caused from something other than the first situation I explained?

Yes in vanilla Halo PC Derelict, see:

http://www.halobugs.com/#?b=143

Occurs in Halo PC/CE and MCC.

I think they show a phantom BSP error in that bug as well, but look at the clips or rockets going through the wall/nades going through the floor. I used BSP Tag Converter (the good version) to rip it down to model format and look at the geometry. When recompiling Tool spits out some minor errors, which I fixed, but the holes remain. Only way I've been able to fix them is to chase them down and rebuild the faces. I don't see anything obviously wrong like overlapping surfaces or anything.

Sidenote: if you take the vanilla Derelict BSP and play it on PC, the aforementioned phantom BSP makes it ingame. However, if you take the very same BSP and convert it to Xbox using Arsenic, the phantom BSP isn't in-game. But the holes are. Vertex data stored differently (compressed/uncompressed) for Xbox.

Updated the dead link. Also included anti-no-collision weapon thing which does the opposite of what anti-phantom weapon does. It paints everything except for things on bsp that don't have collision, probably not a very useful thing to use but hey, here you go ;D

You can type commands in to lock your camera to the AI or empty biped, and type commands to tell them to walk or look in a direction.

Then once you find out the parameters and commands you need, put them in a script for a cutscene and blam.

Edit: I just read in that other thread about recorded animations. Did someone actually fix record animations in sapien now? Or do you do it in halo or something?
