lightmap to big or something

the error message says
"MaterialSystem_Interface_t::AllocateLightmap : lightmap (516x95) too big to fit in page (512x256)"

i think the max i can have my lightmap is 512 and mines trying to run 516
and i dont know why or how, and i only have a very basic understanding of lightmaps atm

anyone know how to fix?

Do you have any ridiculously big brushes in your map? I didn't even know the limit existed, and I tortured the engine quite a bit with huge brushes and high-res lightmaps...

Anyway: What could help is look for the big brush, selecting it's faces in texture mode and then changing the "lightmap resolution" to something bigger. Like 32, actually, in your case, even 17 should be enough. Does the compiler tell you the brush number? You can search for it, there's a function for that in the menu. If you don't know the brush number, just look for a really, really big brush with a large, continuous surface. I guess it could even be a displacement.

Why snark works.

okay, so i found the largest brush on my map (its a giant displacement)

the lightmap on that brush is set to 36 so i changed it to 32 the complied and ran, same error

so i check the brushes lightmap again and it was back at 36, so i changed it to 32, clicked on something else then clicked back on the brush and it was at 36 again...

it wont change, and is this causing the problem?

also here is my compile window

I think this error occurs when you stretch or skew a displacement. Theres not really a way to fix it, you just have to redo the displcement.

Posting And You

hahah

i stretched this displacement to the max

ill delete it and then try

<div class="abouttext">Message submitted 25 minutes after original post:</b></div>
ok for people who might have this problem in the future

my displacement was soo big that the lightmap it need to run was over the limit, to fix this i divided it into 2 sections which alouded me to run it with a smaller light map

i think the limit for one brush is 32

thanks guys

its working now

Actually, if the resolution was 36, you should change it to 37 or 38, so there are less "light-pixels" to be calculated for the brush as a whole. I'm glad you could fix it anyway, though.

Thanks for posting your fix. I am getting this error too, but curiously ONLY when I crank the video settings to the max. Works fine under dx7, go figure

( You better take care of that leak too, that affects lighting tremendously )
