Not the map itself(Unless you edit that in Hammer), but the models, yes.

Unfortunately, I don't think so unless you go in and edit the map in Hammer. You can change the skybox however. I'm not sure if that will tonedown the default map lights.

I've been through most of the CVars available and nothing I've tried has toned down the brightness in the map....

You can change exposure?

What do you mean, you can change exposures?

One way to do it is to lower the brightness of what´s shown on the camera, click "Create Animation Set for Existing Element" and choose the camera you are using. You should now be able to select the camera, then bring down the "tonemapscale", this will reduce the brightness of EVERYTHING, including lights.

Thanks Slumpen, but the question was to darken by using a method other than turning down the tonemapscale...

Recompiling the map to have less sunlight (or night time) is dead simple, simply get bsp source http://ata4.info/bspsrc/downloads.html and decompile the map. Then open the resulting .vmf with the SFM version of Hammer: Steam\steamapps\common\SourceFilmmaker\game\bin\hammer.exe

Then click on 'Map - Entity Report' and search for an entity called env_sun. Select it and then click on 'Properties'. The properties will now open up and you can use the various values from this page: https://developer.valvesoftware.com/wiki/Sky_List to change the sun angle, color and brightness and other values. Once you're done hit apply.

You'll also want to change the skybox texture to match the new sun values you just entered, click on 'Map - Map Properties...' and change the 'SkyBox Texture Name' to match the name with the values you entered from that big list. Every skybox texture has corresponding sun values to go with it.

Finally go 'File - Run Map' make sure everything is set to normal and 'HDR' is checked. Hit OK to compile the map. Once it's finished the new map should already be in your usermod/maps folder ready to go!

Good luck!

Thanks PalmliX, I never was a Hammer guy, so I had no idea how to do this. I've attempted decompiles on maps, but they usually go wrong and knowing about http://ata4.info/bspsrc/downloads.html is a good thing.

Yah I had no idea how to do this either until SFM came out but I've had surprisingly good luck with recompiling maps, it's worked like 95% of the time for me. If you just want the map to work in SFM and don't care about the sun it's even easier because you just decompile, open in hammer, recompile and you're done.

Wow, that kinda worked out for me!
I have no idea what recompiling is, so that was the best solution for me.
Thanks!

Glad it worked Finn.

Decompiling is taking the map, model or a program in its usable language and using software to break it down to its source language, so you can edit it to meet your needs, it is no longer usable the way it was before you decompiled it.

Once you've made your edits, you have to use software to recompile (restack or remake) it from the source language that you edited back into its usable language so you can use it in the map, model or program the way you normally would.

Oh, so it's like taking apart a machine and rebuilding it with improvements?

Kind of... This is a scaled down version of the process. It's how I make giant bots...

But for maps, it's pretty much the same, only different programs (bspsrc and hammer)

Sorry, this video, for me, was too confusing to use....could you, possibly make a video for decompiling maps and such? If not, that's okay....

'Cause now I wanna make it night time. arena_lumberyard.bsp.

I tried that. I couldn't find an env_sun...
