Tends to happen when the centre point of the brush (an X in worldcraft) is near the edge of the brush. Splitting it into two brushes can help when you don't want to change it's shape.

In other news I've been getting brushes that delete their own faces on compile - they generally retain a few but some go missing, just aren't drawn so the map leaks.

Seems to happen when using 45 degree angles that intersect with others, usually I have to bracket the offenders as in Orl's solution - but in a limited resources competition I don't want to have to do that if possible. 

So that's where to look. Thanks. 

I've discovered that I'm no longer able to select brushes from the 3D view in hammer 3.4, no clicks register in that window. The 2D windows work fine, except that it's a pain to pick out overlapping brushes like that.

The biggest thing I remember doing recently is installing the latest catalyst drivers (running on a mobility 9700). Is it possible that installing these could have broken hammer? Has anyone encountered a problem like this and have a fix? And why does the cart on goldrush keep flickering, the new drivers didn't fix that either... 

What sounds like a classic WC bug - go into options and turn off hardware acceleration in the 3d window options.

I'm guessing that you had it turned on before but your previous drivers didn't conflict.

Hopefully that'll sort it out. 

Can anyone explain to me why a trigger_count needs to have a brush model, when it seems to me that it could be a point entity? The QC specifies it as needing one in the QUAKED line, but the code associated with it doesn't explain why... 

All triggers can be point entities as well. 

This may be fairly obvious but how do I get a func_door to light itself in the open position rather than the closed? I have a large door entity that I want to slide into the level but the default position places most of the entity in the void - therefore, it's mostly black when it slides into the level. 

Then check the 'Start Open' spawnflag. 

Damn it, I knew it would be something obvious. Thanks! 

Sweet. Even more brushes left over now... 

Yeah, it was the drivers, by going back to 5.x catalysts I managed to get clicking to work again. The option to disable hardware rendering has disappeared from 3.4, although if you uninstall your drivers then it does default to some kind of software rendering, where selecting things works again. 

I have the same problem and am forced to map without hardware accel, making the 3d view painfully slow on large maps. Visgroups help somewhat, but it can still be a pain. 

Half my problem with attempting to map on the laptop is dealing with the lack of hardware support, and the other problem is the interface is a pain. Oddly enough, Blender, a much more sophisticated and complex app than Radiant shows very little performance loss without the HW acceleration. The source of the problem could be what Bambuz pointed out some time ago that GTK is a slow api. 

Are there any "definite quake 3 custom textures archive" sites out there where I could grab most of the decent publicly available / free to use custom texture and shader sets for quake3?

Lets assume you a substracted a room from the world, added some details and then proceeded to work on other areas of the map. Now, let's say we go back to the original room and decide that we need to add some variety to the wall textures and the obvious way to do this would be: reduce the height of the original substracted room brush, place a new substracted brush using the new texture right on top of the old resized room.

However, we end up with a problem: the new substracted room brush is going to "override" and erase any additive brush details that were placed in the top part of the old room. Since the old room now has lower height, these details now find themselves inside the new room brush which we added later, meaning that the brush "creation order" of the detail brushes precedes that of the new room brush, meaning the new room brush overrides/erases any such details.

What do I do? 

 

Right click on any brush and you can move it to the front or back of the list.

Or, use the geometry tools to split the brush in half using the (admittedly clunky) clipping tool. That leaves the ordering the same. 

So in your case, select everything inside the room and moving it to "last" is probably going to work best. 

Yeh, what Willem said.

Tbh I found the way unreal uses brushes so much more tolerable once I found out you could vertex edit/order shift them, spent a good while assuming Uengine mappers all did some crazy level of layout planning before touching the editor ;p 

Are there any comprehensive 3d studio max tutorial sites which walk you through most important things, from the very beginniner topics to more advanced stuff and techniques? 

http://www.3dtotal.com/

Is a nice resource for tutorials and general stuff. 

3ds max itself has a load of beginner tutorials which show how to use all the basic things like creating objects and applying modifiers, using the material editor and such. 

Assume you have a curved ramp like this one: http://utmapping.wikidot.com/local--files/smc-hu-floor2/smc-hufloor222.jpg Now, assume you want to bend it in the same way as when this same ramp is being used in Arsenal: so that it not only leads from one side to another, but also also goes upwards, still keeping the edges of both "start" and "end" nicely aligned.

I asked around and Hourences told me that UED has no way to do this directly and that since there are no prefab versions of this mesh bent the way I want, I would have to either 1) export from UED to max, edit mesh and reimport back into UED or 2) create my own mesh, texture it from scratch and import for use in UED.

Is this for real? Am I supposed to be have a modelling package like MAX and know how to use it if all I want is to simply slightly adjust an already existing mesh to suit my task? What about scaling meshes, do I also need a modelling package for this?
