Im having trouble with the brushwork of a tank, the entire model is ok but the tower has an "invalid solid structure" error and I want to know if someone can fix it. The finished product would be uploaded as a prefab.

Unless it'll be a moving tank that also could fire like a tank... for all the gods known!!, use a prop model!!, it's waaaay easier to do and could be used like a normal movable platform in HL thanks to this:


Edit: I know, I know, this is a MAPPING help thread, but invalid brushes come always because of brush carving and vertex manipulation, as I painfully have learned after a lot of tries of making brush based props in the past.

if u practice rebuilding the area coming up invalid, you will quickly learn what you can and can't do in Hammer 3.x. Something like this is very easily doable with brushes ;)

Oh!, maybe I didn' explainedmyself, sorry for that, what I try to say is that with mdl. props those problems disappear because of the way they're made and compiled, saving us time of trial-error compiling. Of course I've done complex things like temples, fountains, statues and so on, even there was a time when even I managed to re-create the lv 246 from aliens (APC included), but it taked me boring compiling afternoons ( I've started with an AMD K62 350 Mhz with 128 MB of ram! ) just to fall in those problems... until years passed and I've learned how to make model props and texturing them, I swear that detailing maps for goldsource is way easier so you just focus on proper lightning and story-gameplay matters.

I can't open the map for some reason, but if you want to check out one of my prefabs, go ahead and use it. It doesn't look as detailed, but you can always add more.

Wow! The tank looks nice!

When I downloaded it, after "fixing" it, I either fixed it or broke it even further, because I saw invisible faces in Hammer & Sledge Editor (but I was using the .map format for them), but in Jackhammer, everything turned out to be geometrically correct.

So, the error is, when more precisely looked at, a "faces not planar" error.

The problem was, you didn't use the Ctrl+F command, it splits a face into 2 faces, which is good for cases when you get the "faces not planar" error. So you just had to split some faces into more faces, and then you would get a "brush not convex" error, so you'd then have to cut the brush itself. And then it would have been fixed, if you knew where to cut it.

In case you don't know what I'm talking about, examine this fixed .rmf, or .jmf if you have Jackhammer:

You'll see (if you download my "fixed" version) that there are more polygons on the tank tower, which are the result of face splitting.

I'm unfamiliar with Jackhammer. If you have 2 faces on the same plane, you get a coplaner face error which will prevent your map from compiling.
