STUCK: Hall of Mirror problem due to cameras

[NeonsStyle]

Hey Guys,

 

I've been stuck on my new map for awhile now, ever since I decided to use cameras to project a scene to

make a canal look like it extends further than it does. I've been trying to nut it out now for over a week,

and just can't resolve it. So if anyone has any ideas, I really need them lol

I don't know whether I get it right, I but see you have that camera in the same place where player can move around, and it seems the HOM effect occurs only when you look directly at it, regardless of the obstacles in the way. What about placing that camera and the view in a place that is completely sealed off from the playable area?

 

Edit: Nevermind, now I see that it is in a sealed off area, but it still occurs when you look at it. It's like two skyboxes fighting for attention.

Yeh, however in the camera skybox, it all works fine, it's only in the projected skybox that things get screwy. Doom3 used

this camera in their levels and never had an issue with it, so I don't see why it creates a problem now, unless it's the sky portal

that's doing it.

This is just a wild guess then, but have you tried moving this scene around? Right now, it's nearby, almost behind the wall it's projected on, maybe looking at the wall and what's behind it causes this weird error? Again this is just me guessing, but if the scene was like on the opposite side of the map, so you can never look at it and the target wall simultaneously?

 

If anything else fails, you could use an old trick from Dreamfall, where such "corridor ends" used just static images. It just has to be far away, and you could sell that illusion better by mixing static background with some meshes. Not to mention it would probably be good for performance as well.

Try g_enablePortalSky 0, 1, 2, -1

Or upload the map somewhere so that we could look at it.

Yeh I have done all of those Judith except for the still image. I did think of that, but it's not something I'd want to do unless I had to. As for what's behind it, it's a

caulk wall.

 

@duzenko, I'm not exactly sure where you want me to apply those spawnargs. I put them on the projection patch, with all those settings, and it made

no difference.

 

I'd upload it, but I prefer to PM to someone, so if you want to look at it duzenko, I'll pm you a copy.

[peter_spy]

I thought it was caulk, and my first thought was to change it to a regular texture, but you probably tried that already.

g_enablePortalSky is a console command.

Did you try to put an opaque solid wall behind the mirror?

[stumpy]

you could try to put the texture metal/flat/gold01

 

on the void side of the brushes where the hall of mirror effect occurs.

Just tried that Stumpy, and it didn't work. The projection screen (a func_static) was a patch so I couldn't place

a texture on the back so I replaced it with a brush. It worked as a projection, but still had the HOM effect.

[duzenko]

Anyone ever used cameras in TDM missions?

In terms of performance, do you think it is going to be faster? I think camera is being updated each frame so one way or another it is always drawing everything.

Does the camera still work after save/load? It does not for me.

...

Regarding your problem (parasite pixels in the skybox).

I think it's caused by the water shader in the camera view. It requires to save the current frame to the texture that is also used by the skybox pass.

What you could try here is use a simpler, non-post-processing material for water in the camera area.

[Obsttorte]

I've used it in some tests. Didn't save/load there as far as I remember, though. I've experimented using it as a possibility to peek through keyholes. Haven't finished that yet, though.

[duzenko]

Definitely worth trying console command g_enablePortalSky 1.

If that and materials does not help then we should pronounce 2.05 incompatible with remote cameras.

That has no effect in the level. By the looks of it it seems it might be unsolvable at the moment, and maybe also not much

of a advantage over building the area out.

 

I was trying to make that area look a lot large without needing to build it and draw alot more tris. I figured just drawing

a screen would be a lot cheaper performance wise.

Unless you actually put a static picture on it I can't see possibility of performance gain.

Ok, thanks Duzenko. I'll just build it out.

 

Thanks for your help.
