I assumed you are talking about quake's stock textures. If you're just using a poorly tiled custom texture then I can see how that would be pants. 

@Kinn
It's just an eyesore having double lines of mortar at regular intervals on brick walls, but it's a minor issue so i'll finish the map before looking into it.

Moving on, how can I include custom models in my map, I was able to modify the .fgd file for Trenchbroom and place the models but Quakespasm complains that there's no spawn function for the entities. 

Is it a custom texture? Sorry to be a pain, but any chance you could post a screenshot? 

No problem: https://s3.postimg.org/xxphtyncj/spasm0000.png 

To get custom .mdl files (things like trees, etc.) in to a map, one way is to run the map under a mod like AD or Quoth. Both of these have entities (AD's misc_model and Quoth's mapobject_custom) for this. 

So would that simply entail using the .fgd or .def file included with AD and then running the map under AD?

Ah, right - wbrick1_2 from rogue.

I've made a fixed version for you which you can download as a .wad here: https://drive.google.com/open?id=0B74rZcw0hvZpT0dOSzZCN0JlNWs 

I've slightly improved it...

Yep, pretty much just load the AD fgd in trenchbroom, use the misc_model entity in your map, and install the .bsp in quake/ad/maps/, and load the map under AD in the engine.

You'll need to put the .mdl somewhere, and then put the path into the correct field of the misc_model entity. Normally, mdl files go in "quake/mod_name/progs" but you could also put it in "quake/ad/maps/your_map_name_XXX.mdl" which might be more tidy when it comes to distributing the map.

Thanks, having the fixed texture from the start should save me having to manually replace textures later.
@ericw
Great, that simplifies things a lot. 

Hello,

I'm a new mapper. I'm using Trenchbroom2 and I often have a problem with building frames that fits around the arch-shaped doors of Quake. I can't easily get all sides of the frame being the same thickness.

Ideally, I would like to extrude the frame from the arch-shaped door's outside faces. When I extrude, I would expect the shape to snap to a grid aligned to the surface normal that I extrude from. However, when I do that, my extruded brush aligns to the axis-aligned grid, so when I do the slanted parts of the frame, they don't have the same thickness. This makes it impossible to have a door frame with a uniform width.

The other way I found to do a uniform arch frame is to rotate brushes around the door. This way, the thickness is guaranteed to be the same but it's very restrictive on the angles chosen, error-prone and complicated.

Do you guys have any tips to help me on building arches or similar structures? 

You can rotate in smaller increments in TB by entering a value in the menu bar and using that. The Gizmo sadly always rotates by the same interval :(

I think I would have to see pictures to understand what you're trying to do when you're extruding.

Here a small tutorial i did for arches in TrenchBroom a little while back. 

This is an example of what I want to do (see the metal frame) :

This one I did by rotating a piece around a brush with the door texture, cutting the door to fit with the frame. It doesn't give me the granularity I would like.

Ideally, I would like to be able to cut the door however I like and then extrude the frame from each outer faces of the door's brush. But that doesn't give me a frame with a uniform width (because of the snapping). 

And thanks mukor for the arches tutorial! It doesn't solve my problem but it seems like a way that generates cleaner geometry than how I was doing it in the past. I will use this way in the future 

Apparently I forgot to use my name on the previous replies... sorry about that! 

Does anyone know what's causing this weird shadow?

I'm getting some strange behaviour around the disturbed coffins I'm placing, another one i've placed allows the player to walk through the side of it, and this one seems to cause janky shadow behaviour. 

Yeah, both of those are probably technically compiler (qbsp/light) bugs.

The lighting one is caused when there is an obstruction close to a face (less than 2 units away), so the coffin is preventing the lighting from getting set up properly for the floor. I actually will have a fix for this in the next version of my light tool, but for now you can either lift the coffin off the floor by 2 units (might be visible), or turn it into a func_wall and set the keys "_shadow" "1" so it still casts shadows.

The bad collision is just, qbsp tends to mess up on rotated geometry. Try making that coffin a func_wall as well. 

That fixed both issues, thanks. 

Hello! I am newbie, and I currently got inspired by R.P.G.'s map "And All That Could Have Been".

I read from Quaddicted description, that it used Speedbase textures, and I want to play with those.

There is some aesthetics that I really like.

appreciated much! 

I've realised why I don't see stuff like the coffins I'm placing commonly in maps, it seems that once you rotate angled surfaces on 2 or more axis texture lock fails and it becomes night impossible to align textures correctly. I take it I just need to be more conservative with rotating complex geometry?

Secondly, I'm able to place models using AD's misc_model, but as I can't see the model in-editor precise placement becomes tricky, is there any way to enable a preview, or a flag that will bring the base of the model flush with the surface above/below it?
