hey, im suprised i havnt run into this before, but is there an easy way to make a sphere inside hammer? ive looked around but i cant find any way short of rotating a cylinder a lot, which im sure would case problems.

You can make one out of cones. Just cut the tip off a cone and you have a slice of a sphere. Stack up the slices to make the whole thing. Example:



I put it in a prefab library:
http://superjer.com/lies/SuperJer.ol

Just put that file in your Valve Hammer Editor\Prefabs folder to use it.

ok thanks
one more thing, is there a way to make it hollow without exploding something?

HOLLOW?!?!

Good Lord, man!! Hollow?

That's asking a bit much. I don't think there is any even remotely clean way to do that in HL/BSP. Why do yuo want to do that, anyway?

AHA YES! my ghetto technique!!! listen up.. copy and paste your sphere, and rezize the copy one to be a little bit smaller than the real one, then right click it and press carve...

so:

You can go ahead and try carving that thing but it's going to be a complete mess. It might not even compile.

Out of a certain morbid curiosity though, I did make a hollow sphere out of only triangles.

This is NOT a good idea. BSP is about blocks not individual triangles.

But anyways, here it is:


Updated SuperJer Object Library: http://superjer.com/lies/SuperJer.ol

Just DO NOT expect it to work out all peachy.



Do you just want a spherical room? But with no walls on the outside? That can be done somewhat safely if you just turn my hollow sphere inside-out.

Ok I also added a flipped version of halfsphere_hollow_large called sphere_room which you can probably use as a spherical room but NO GUARANTEES!

ok thanks, ill try that

yeah i tried the whole use a sphere and shrink it inside and carve thing a while ago.

good god that was tramatic for ZHLT.

hmm.

so i made a test map with basically 2 of the half-hollow spheres put together and tried to compile it. everything goes fine untill it tells me i have a leak (i already knew that) and then... nothing.
it ends on "Leak pointfile generated" and does nothing. here it is:


Warning: === LEAK in hull 0 ===
Entity player_weaponstrip @ ( 256,-192, 224)
Error:
A LEAK is a hole in the map, where the inside of it is exposed to the
(unwanted) outside region. The entity listed in the error is just a helpful
indication of where the beginning of the leak pointfile starts, so the
beginning of the line can be quickly found and traced to until reaching the
outside. Unless this entity is accidentally on the outside of the map, it
probably should not be deleted. Some complex rotating objects entities need
their origins outside the map. To deal with these, just enclose the origin
brush with a solid world brush

Leak pointfile generated


----- END hlbsp -----

before that is just the usual blabbering of the compiler.
the wierdest thing is that the weaponstrip is very much inside the map.

The compilers might just not like all those wacky triangles. I'll take a look at it later. I was going to try to use that sphere in a Portal map.

Can you load the map in-game or not?

nope.
when the compiler gets stuck, it did export the .bsp or so it seems, so i tried putting it in my maps folder by hand but the game crashes pretty much instantly.

Well there's a lesson here:

You can't make interesting shapes out of brushes.

blech.
well i know ive seen it done in a few maps. theres one by the infamous Nipper called Blahh or something like that where its a spherical room that has low gravity inside, but when you leave it turns regular again. i know how to do that but its that damn sphere....
