"tell a programmer" Index buffer

I just got an error that says "too many indices for index buffer.. tell a programmer (33168>32768)" Literally that is what it says. Any hints?

Well... tell a programmer. :smile:

This is the sort of thing that they'd internally pass on to one of the programmers, who could probably track down the problem and help them fix it. Unfortunately this is one resource Valve hasn't made available. :smile: Is it causing an actual crash, or is it just a warning that shows up in your log?

I got something similar -



It caused an actual crash for me - I restarted and all was well.

Yea well all the mapper woudl be siting at valve and when they get this
error would probably walk past fat nwell to the programming department
and get one of em to help them.

I'd suggest you do the same. Happy flight !

No seriously, erh ... I don't think there's a way to solve this ... you could try mailing Valve or something.

Tbh... I doubt Valve would care.

I think they would tbh. If this problem occurs enough I'm sure they'll just patch the SDK in the next update.

yeh i think so...well i just hope so...cuzz i dont want this problem coming to me then i dunno wat to do lol...

The first number is the number of indices and the second number is the maximum indices you can have. The fact that it's 32768 is interesting... A two byte unsigned integer (which is what you'd normally use for an index) goes up to 65535...

Tell the programmers at Valve to up the buffer size to 65535!

I got one of these when I made a giant func_precipitation in my map and
then stood on top of a tower where I could see most of it. I
suppose it could be particle system related too.

Yeah, it sounds like there is too much of something- in Raeth's case, probably rain drops- or perhaps something is overflowing?

Nickelplate, did you have a leak in your map when this error happened? I'm getting the same error in one area of the map I am working on. Its a cave like area but its not any more complex than the rest of the map, it has displacements here and there.
The map does have a leak so that might be part of the cause also... Just wondering if anyone has anymore information on what can cause this error. I searched the net and found next to nothing.

that is when i got mine!!! precip and tower!

We get this error because each raindrop, particle, sprite, and disp (i think) has an index, when you are viewing too many at a time it overflows causeing the crash! very basic i know, but that's all i got.

I also received the index buffer error. I believe it is because I have a lot of cydrilical brushes that have been hollowed out to appear as pipes. Hollowing a cylinder & deleting the end pieces creates new brushes equating to however many faces the original cylinder had. I opted against using props for the same as it seemed that props caused more problems than solid brush entities. I deleted many of the cyndrilical brushes & still encounter the same problem. I pose the following questions:

1. Is it possible to increase the number of allowable indicies?

2. Is using solid brushes more efficient than props?

3. Will reducing the number of faces on the cylinders solve the problem?

4. Will applying the nodraw texture to non-visible faces of the map help?

5. Will grouping similar brushes together help?

My map has also ALOT of displacement, along with blended textures (and subsequent alpha displacement). There is also a lot of texure scaling. For example, a 48X96X44 unit brush with the woodshelf texture. All sides are texture-scaled to make the entire brush look like a full bunk of lumber. I have deleted a few of these brushes to try to solve the problem, without compromising the theme of the map. I still get the same error. The compile log shows no errors, but when I run the map in-game, it crashes. Please help.

Yours,
