to making any prefab is to at least scale the x,y and z coordinates to double what you intend the object to be in game.

I'd be glad to write of a little tutorial but someone would need to point me to a no frills screen capture program, or if there is screen capture built in to Radiant, tell me how to use it.

BTW, once you have the coil built, hallowing it out for player walkthrough is tremendously easy. 

You set the width of the spotlight cone with the angle key (default 40 degrees). In my Light tool you can also specify an inner cone for a more gradient spotlight. Please check the readme for details. 

As you mentioned, the four-sided planes made on these brushes cannot be contorted so their edges meet up. Unfortunately, because of their shape, you can't split these brushes into triangles. Without using lots of brushes for each of the 12 sides on the pipe, and without hollowing, I don't know how to accomplish this.

So basically there wasn't much point to this post.

Are you still in Greensboro from August through May? 

 

Phait: some ingenious bastards created an installer for radiant 1.4 and 1.5 makes it almost idiotproof to install. No fink dependencies or compiling your own source bullshit, it basically does everything for you and makes an application package with all the radiant subfolders in it. take a look if you have a spare mac: http://www.redsaurus.net/gtkradiant/index.php Runs beautifully.

Headthump: If I recall the pipe i was taking screenshots of was 512 units across, which was the size I wanted it. Theoretically those curves can be made at almost any size and scaled almost to any size; it just worried me that such a large pipe had interior points on such a small grid. If I try to make architecture inside the pipe that matches up to the same proportions, it will probably end up aligning to a grid of 4, which is rather smaller than I'd prefer to go. But I suspect it'll be inevitable. As long as all the points match up, QBSP's cool with it, right?

That screenshot you got there is pretty close to what I was envisioning. How well does that snap to the grid? Will it scale well to about 8-16 times that size? and what do you mean by "hollowing it out is easy?" If you mean using the hollow command in the editor, that is a really awful idea, and a surefire way to make qbsp hate you.

RPG: Yeah I know it's hard, I'll keep trying. And actually yes I'll be coming back to gboro sometime this Aug, even though I graduated last may. You still in, umm, chapel hill was it? I'll try and catch you on irc sometime. 

Spare Mac? I have a Powerbook :P

Seems Radiant even with installer, still depends on X11 - which I had installed once - I have Radiant on CD for OS X... but ah, just confusing setup. Anyway - it also requires 10.3 and I'm on 10.2 yet. Oh well. 

correct, the scaling will work fine at larger sizes.

lol, hallowing is a horrible solution to this, unless you are dealing with large areas and a well contained surface (that doesn't split up adjacent brushes in the compilation).

Instead, I would start out with three seperate spiraling brush builds to represent the cieling, wall, roof than the way I started here.

My example above was an octogon, given it is all 45 degrees, the math stays easy. I'm working on a 12 poly sided spiral now, and to be honest I'm not encountering the problems RPG mentioned. It makes me worried I am missing something.

I avoid using the vertice tool, and instead I move the sides into position and cut. It is less messy that way. 

phait, doh you're right, but it's apple's X11. I suspect macradiant will always be X11 only unless somebody makes Aqua-native GTK2-wrappers or something, which will probably never happen. And you should upgrade to Tiger (10.4), stuff like Spotlight makes it really worth it.

Headthump, can you show me a .map file? mail me if you'd like: owen dot greenwood at gmail dot com 

I'll send you the first map. The second isn't ready for puplic consumption. 

Check your Guilford e-mail, and then update your profile if that's obsolete. :p 

but the mapping help thread is surely not the ideal place for this conversation. :P 

that map I sent you, Grahf. I wouldn't be able to sleep at night without straightening that stuff out. 

Thinking about recent questions posted here, I built an acending hollow pipe (that the player can walk in) spiraling around a cylinder. It worked out well, so I cloned it and mirrored it to make a hollow tube figure-eight. Again, no problems.

I am curious how any of that would be possible without using the vertex tool. Can curved tubes be sloped without vertex editing? 

I think vertex editing is the only way. In Radiant, edge dragging or skewing makes really messed up brushes that don't align right.

Do you have a picture or .map file of your creation? 

i use them; they work in some situations; vertex manip works in others; you just have to know when to use each one. 

I'm not set up to take screenshots in the editor, so I sent you the .map file instead. 

share the love. I'll host it for you if need be. 

I meant that in this particular case of curved spirals, edge dragging and skewing weren't working for me. rereading my earlier post, that should have read "I think vertex editing is the only way to make these spirals." That was a vague blanket statement the first time around. 

There are some cases where skewing can be the only way to achieve the desired result (at least, in a sane amount of time). Especially in an environment like Radiant where the editor will not allow to to create invalid brushes while working.

A good example is if you want to create a curved, 12-sided pipe using brushes. We all know you can't rotate on any angle other than 90�, and it would be completely insane to try to move each vert into the proper position (even if that is possible in your editor)... the only viable solution is to skew and use the clipper tool to finish up, once everything is in position. 

I have a small problem with light. There's always a fullblack stripe to the left from the brush that I use a lightsource (32x32x8 sized). The light spot is situated in 16-32 units in front of it.

Here's the screensot of it: http://www.quakemaps.nm.ru/misc/light2.jpg

Any ideas of how to avoid it?

the commands line is: light.exe -fast -gate 1  

removing -fast and/or adding -soft or -extra4. If it's still there it could be that you're using an editor that requires enhanced texture positioning (e.g. QuArK or Hammer), then try adding -etp.

The last thing I can think of is that there's a brush problem (misalignment), it can sometimes cause bad shadows. Try manipulating the brushes and see if it helps. 

I did some stuff, like a spiral staircase (a map in progress) but a ramp instead of steps. Thanks for help from func people and czg especially.

So don't read if you already know.

Since it is a twisted surface, it must be constructed of triangles. (The slope is steeper on the inner curve than the outer curve, so they can't be in the same plane and thus can't be edges of the same face.)
Requires vertex editing in Worldcraft and isn't that hard.
That technique should be extensible to tubes and all the like too. I think maybe sometimes by skewing the brushes and sometimes by rotating them. One by one.

I'm off now. 

skewing with multiple brushes selected in Radiant does wacky things. At least, it doesn't move them all as a unit. 

radiant "skew" isn't really skew. it's more like "drag all the edges that belong to this face." 

Worldcraft error:

I was innocently mapping away, when i clicked on the camera button. There was no camera to be found now. It seems to have disappeared. Even when i closed the map, and then reopened it, no luck, still no camera.

What's going on?
