For those using TB: I've only just noticed that I can see three lines in-editor, an orange, blue and green one, corresponding to the x, y and z axes (not necessarily in that order). Is the point where they intersect the centre of the world (i.e. 0, 0, 0)? 

1st. Its possible to scale brushes up/down the amount you want with some editors. Trenchbroom currently doesnt do this for you.
2nd. Yes. 

 

Scaling complex brush shapes isn't something you want to do in Quake anyway.

What I do sometimes to scale up cylinders is to cut them into wedges, and pull the faces on each wedge outwards/inwards. In editors like TB and Radiant which preserve the adjacent angles of other faces when you pull on a face, this works really well. And in Radiant, which has CSG-merge, you can merge all the wedges back together into a single brush.

Otherwise, what I actually do more often, is to just remake the shape I want at the bigger size. This style of curve is what I most often use, and it's all about the ratios (interior angles have 1/4 and 1/1 slopes, outer faces are 1/2 and 2/1), and it's easy to make at all scales with the clipping tool. 

Really useful advice! 

cut them into wedges, and pull the faces on each wedge outwards/inwards

Works like a charm! Thanks again. :)

Currently using only TB, so I have no way of merging the wedges back together -- does this matter much? Am I likely to run into problems when I have 12x as many brushes per cylinder? 

No, it doesn't really matter, Qbsp will cull the hidden faces anyway. I find it easier to work with less brushes whenever possible though. 

I have another question, though:

When I cut a 12-sided cylinder into wedges and extend the sides as per Scampie's advice, it works perfectly.

However, I just tried it with a 24-sided cylinder, which I created by clipping the corners of a 12-sided cylinder, as shown in czg's curve tutorial: http://www.quaketerminus.com/hosted/happymaps/curv_tut.htm (2nd image from the bottom of the page). Somehow, it doesn't seem to work: when I drag the edges outward, they don't line up.

Is there a mathematical reason for this? And is there a fix/workaround? Does anybody know? 

When I made the grid size really tiny, it all lined up. 

There is this sudden blue to brown transition:

It's a blue sunlight / sunlight 2 with orange coming from lava.

The top of the rock looks hand painted in blue. There should be a smoother transition to brown. What's the best way to do it, in your opinion? 

Check the keyboard shortcuts, there is a command to build the convex hull of the current selection. The effect is the same as CSG merge. Also works with faces; that makes it easy to build connecting brushes. 

That was it. Thank you. 

Thank you.

However, I've looked through the keyboard shortcuts several times now and I cannot find anything like what you describe... 

Fyi 

What is it called exactly? I mean the shortcut I should be seeing? 

Is there anything similar to hl2 "play everywhere" flag for sound entities to make music play not as a 3D positioned sound, but as 2D sound? Does any mod support it, quoth or anything else? 

it's called "create convex hull"

Theres more on it here -

https://github.com/kduske/TrenchBroom/issues/706 

But I still don't see it. There's nothing called "Create convex hull" in my keyboard shortcuts list, or anywhere else that I can see... 

I just installed TB2 again and I remember how much I really hate it. I can't even create a brush properly, wont be using this unless a legacy brush creation option is added.

Just had a look at all shortcuts and I couldn't find it. Maybe re-open the issue in github? 

You can create brushes by activating the create brush tool. In the 2D views, its pretty much as it was in TB1 - just drag out a brush. In the 3D view, it's different for now. More powerful (you can create arbitrary shapes), but yeah, you can't just drag them out as simple as you used to be able to.

If you chime in and add issue reports, I may try and add the legacy way back in. If you just hate in silence, I can't do much ;-) 

I struggled for a good 15 minutes just then to draw a simple square. I'm a huge fan of TB but the changes to the brush tool in TB2 really turns me off. You say you can drag out a brush in the 2D view, most of my work is done in the 3d view after 2 years of mapping like that (the original vision of the editor was pure, I haven't looked back!).
I'm sure the new brush tool is really powerful in it's own way but TB2 feels like a completely different editor now. Funnily enough I still have one of the older TB2 builds somewhere, I made my first Quake 2 map using that rather than the newer version because of the brush tool.

Also, I thought I did raise this on github when you first introduced the feature. 

Do you remember where? 

Is there anything similar to hl2 "play everywhere" flag for sound entities to make music play not as a 3D positioned sound, but as 2D sound? Does any mod support it, quoth or anything else?

Use a play_sound_triggered and set the speed key to -1 for the sound to have no attenuation, so heard equally loud everywhere in the level. 

 

The sound will still be positional though. The only way around that is custom qc and playing the sound on the player entity.
