My first guess is that vrad is crashing from too much surface
#massive gmod map will not render lighting, how could i fix?
shut sail
here it is then
zenith sierra
yeah looks like a crash to me
Vrad is a 32 bit program and thus can only use ~4gb of ram
It is also not very well optimized
There are a few things you can do though to try to help it
- Split it into more brushes. Large brush surfaces eat up a ton of RAM compared to multiple smaller brushes
- Raise the lightmap scale across the board as a baseline. This will greatly reduce the amount of RAM used map-wide. You could try to raise everything to 32 luxel scale as a starting point
shut sail
alright, i'll try the second one since i died having to split up the map
shut sail
it's worked, thank you!
shut sail
kind of nevermind, the flashlight issues persists and i'd also like to know how i can prevent all the ambient light from dispersing throughout the room so it remains dark and you don't see the strange low ambient light in source
zenith sierra
can I see a pic of what you mean
shut sail
for the flashlight or ambient light?
the flashlight was demonstrated in the pic attached to the post
but if it’s the ambient light i can take one
zenith sierra
the ambient light
shut sail
alright
here, also demonstrating the flashlight better
past the light directly coming through the arch doorway i want it to be dark so i can use my own lighting better
in the top left corner you can also see those weird jagged noticable lines that i was talking about
really noticeable here wtf
and one more image of the fucked up flashlight
zenith sierra
the flashlight, I'm unsure off the top of my head
but regarding your world lighting, what settings are you doing right now?
shut sail
i tried turning the ambient light down to 0 and even -1 but it still remains
regular brightness is at 200
no other lights in my level other than the light_env
zenith sierra
no I mean like all the settings
shut sail
all of them, in my map and lighting and anything else i could possibly tune?
zenith sierra
just screenshot the light_env settings I mean
zenith sierra
yeah don't do -1 on ambient
that's only gonna cause issues, if you don't want anything just put 0
but that also being said
what settings are you compiling on
shut sail
0 also didn’t seem to help
i was rendering vis on fast and rad on normal, and don’t really bother touching the advanced settings
zenith sierra
you may need to add -final to vrad
shut sail
in the advanced settings?
zenith sierra
yes
royal glacier
If you don’t want any ambient you could try -extrasky 0 maybe? Or -bounce 0 to prevent light inside
shut sail
those a settings you input in the compile window?
royal glacier
yeah like this
shut sail
alright hahaha
shut sail
If you don’t want any ambient you could try -extrasky 0 maybe? Or -bounce 0 to ...
this worked for the ambient light
the fucked up flashlight is the last remaining issue
shut sail
went searching for specifically this and it appears no one encountered the same issue
does it have to do with my surfaces/textures?
zenith sierra
It could be because of the textures but it should be broken in a different way if that's the case
zenith sierra
no its related to... the materials themselves
i dunno what material it is so i can't really tell you anything in that regard but some materials you can pick from the texture browser have shaders that you aren't really supposed to pick
zenith sierra
what is the shader though
shut sail
let me check
lightmappedgeneric
though i have the normalmap texture in another folder, does that create issues?
zenith sierra
in another what
shut sail
wait
i meant folder, sorry
i have multiple types of the same texture that use the same normal map, so i keep it in a different folder
it's properly linked in the vmf, idk if that causes issues though
zenith sierra
no it doesn't matter
shut sail
alright
i saw something about texture scaling possibly being the reason though i can't imagine that lowering it from 0.25 to 0.15 will fuck up the way the lighting renders in that way
zenith sierra
It shouldn't
shut sail
the mystery remains unresolved
noble mantle
Have you tried compiling with -luxeldensity 0.1 or something like that?
shut sail
will that change the lightmap scale at all?
noble mantle
will that change the lightmap scale at all?
Yes, it will lower it
The goal is to see if the issue is caused by the size of the lightmap, or if it’s caused by an issue elsewhere in the map
shut sail
lighting probably will not render then but i will try to see if that fixes it at all
if it is caused by scale i’ll probably just have to design the map so that you won’t need a flashlight
shut sail
didn't lower the luxel density unless i put it in the wrong spot
shut sail
i've noticed that this issue, or something that appears to be similar, occurs with a lot of lights. idk if this helps at all but it seems to broadly apply to any lighting instead of just the flashlight
zenith sierra
looks like caused by lightmap scale
zenith sierra
hate to see it
shut sail
it must be turned lower?
shut sail
might not be
hold on
it is aligned
a lot of them even happen on the same brush face

From what i understood from your description, i can recommend splitting your bushes by 2 4 or 8 divisions fora a map that is ¾ the size of the grid, and a out your lighting, go into the lightmap and make the luxels bigger as in less luxels, i am sure thers a limit to how much luxels you can have in a map THAT CAST SHADOWS, granted your env_light is not perpendicular to the X and Y axes
Alzo the problem could be something different so send your compile log and compile often
