Hello there, I need your help for a little problem I've been trying to solve over the last few days. All my attempts and all the people I asked about had no idea how to over come this.


Basically, I have geometry, notably underground caves, that are way below the water level. Problem is, Fog works with planes ( $ symbol) and thus, I can't make it ''Volumetric''. Applying fog to that ocean of mine therefore makes the area below look like it's underwater.

If anyone can help solving this, I'm really out of ideas.

portals?

I am not sure if i understand this correctly, but i am leaning toward an answer like, everything below waterlevel is filled with water, unless you have some type of airlock.
Is that what you are doing?

Use exact portals or normal portals. Then when it's ingame, open the BSP tag and set the fog from 1 to 0 in that portal.

Chrisk, how do I know which portal is which and how will the game know which fog to use? since fogs aren't referenced by numbers like BSPs are, since I have only one I guess it would work but still, is it something you already tryed?

Its pretty much guess and check. The halo engine was just plain not made for this.

Alright, will try tomorow when I get up. Thanks alot for your help!

your problem can't be helped.

wow, pwnd. and masterz, be optimistic & don't jump to the worst solution possble next time you post.

Even with setting fog to 1 in Kornman's guerilla?

Ignore Masters.

could you explain this in more detail, particularly "ingame". So far i haven't found a solution for this, only that anything above/below the fog plane will have fog, even with portals

Actually, What I believe his solution will do is enable atmospheric fog which is set by the sky tag. This or use the only fog in my palette... Either way I can't test before I have a steady build.

And here's the result: 03.11.10 12:21:30 EXCEPTION halt in \halopc\haloce\source\tag_files\tag_groups.c,#3157: #1 is not a valid structure_bsp_fog_region_block index in [#0,#1)

Sorry, I meant in-sapien. Basicly, you need to open the BSP tag and find out what cluster the tunnel or underground area is and disable the fog there. (by changing the 1 to a 0)

There was a good post about it somewhere around here.

The BSP tag or the scenario?


I'm not sure you understood the problem. I'll make a drawing to help out





Light Blue is the Water plane
Dark blue is where I want fog
Yellow is where there will be fog, including the brown area that's below water level and that I need to take off so that this cave that's underground is Not considered underwater

Fake water plane

I'm speaking from experience, although Chrisk seems to have a good idea, his is worth trying although I don't think it will work..

It will work, Bungie did it on c10. In Halo, fog is everywhere or nowhere. If you assign a cluster (portal) to have a fog plane in it, the fog will show up when your standing in that cluster, but if you move to the next cluster that doesn't have fog assigned to it, you will see no fog. Even in the area that has fog assigned to it.

Long story short: If you want to do this, make sure you can't see the tunnel directly from an area that has a fog plane.

And it's in the BSP tag.

Ah, yes, the elevator shaft....

B30 did it by using different bsp's. Easiest solution would be to do the same.

What about Newbkilla's (or was it Killa_FTW's) map? Didn't it go under water? The one with the island and massive cliff with a beach and junk.

I don't recall that map... anyone has a name?

killa's map didn't go underwater. He was able to fake it by using teleporters and tinting the windows. The maP was delta cliffs.

That's what I thought. Then I believe it's not something that's been done before and all testing done so far was unhelpful towards this. Unless someone has better I guess it'll have to stay without fog.

Put it somewhere in the sky, hidden from sight, and put a teleporter by the water's edge. Then make the inside of the teleporter look like what's actually on the other side, up in the sky. Nobody would notice...... Lol. Of course, the teleporter would have to be shaped like the cave entrance.

Do you even know what portals in halo are? Not teleporters.

Opsy, if you look at insomnia... the secret room is below the map's sky water level thing. maybe that can be used as an example to your research to fix this problem. (no, i went in the secret room, looked around. enjoyed. and left.)
