"huge winding split removed brush": map fucked up

(]UBC[ McNite) #1

lalalalalala I just lost the complete work of a whole day lalalalalala

ok, I m ok again… everything was fine until I made some tiny brushes I must ve forgotten long ago detail brushes to improve my VIS… next compile (q3map2 2.5.10 + q3map2build as front end tool, BSP: -meta, -v; VIS: -v) the map was all fucked up. This is what I found in the logfile:

So as far as I understand it, q3map2 lost most of the brushes/surfaces and just didnt calculate them, which is exactly as the map looked: like made of caulk without any textures for most of the part.
The VIS-stage was ok though, no relevant changes there, apart from some improvement (reduced visdatasize by 10.000 in comparison to the compile before).

For your information some parts of the VIS stage:

--- Vis ---
Loading E:\ETmap\etmain\maps\mp_theriver_2nd.bsp

  1212 portalclusters

0...1...2...3...4...5...6...7...8...9... (5)
      5 average number of passages per leaf
     14 MB required passage memory

Suggestions anyone?
Is there a max of detail brushes that the engine can calculate? Is it less than 16.800?
And: No I didn’t safe my map before I made a dozen structurals detail :angry:

sorry I cant help with your problem, but I did notice your using an old version of q3map2, were onto 2.5.16 now, which you can dl from my sig file, well the windows version, I couldn`t fit the unix version into the sig text.

Ok, I took the mapfile and deleted a shelf and some boxes to reduce the amount of detail brushes. Compile was no problem, everything fine.

Then I imported the shelf and boxes (had them prefabbed before deleting) into the same map, compiled with the very same settings: everything fine :eek2:

Well I m glad my map works again, but it isn’t really logical is it?

It sounds like you had a bad brush somewhere. Did you try brush cleanup ?

WARNING: huge winding <<< I know this one from too many structural brushes

How do you ‘know’ that ?

(]UBC[ McNite) #5

@ brush: had only 1 brush indicated by brush cleanup but cleaning it up didnt help me with the issue

@ know: when I started the map I didn’t use detail at all… so I ended up with structurals only and iirc I got a huge winding from that, it forced me to start using detail

when using brush cleanup, run it a few times until it reports ‘0 invalid/duplicate planes removed’ as sometimes it doesn`t get them all the first time.
