What do i need for this?

Was already fixed.^^

The reflections of black and purple are missing textures. It means you need to download the textures to see them (You probably know this already XD). Still, amazing map!

Thx for the Info,
I did run the cubemaps command.^^
But I doesn't really understand cubemaps though.^^
I read something but I only figured out that they make a better 3d atmosphere.^^

Hi MrSmile! Hiyu here. I've spoken with Stinger and we're fine with this, so no worries :)
We actually made all of the "dev" textures for rooftops_lost - they're all high-res and broken-looking, that's the art direction we were going for - but I can see how there'd be demand for a non-devtex version.
One thing - please update the map with your own cubemaps (if the map is HDR, remember to build cubemaps in both HDR and non-HDR mode). If building them doesn't save them to the file, there are workarounds. Do *not* tell people to run the buildcubemaps command, as this will most likely change the map file itself and they will no longer be able to play on the server as the files will differ.

If I don't want it to be used, I would set it to privat, does that makes sense too you?^^XDDD
In short yes you can host it on your server like hundreds of people do I guess?^^XDDDD
And there is no branding.
I only modified the Map because I liked the map, and wanted to have it prettyer on my Clanserver.
In short YES you CAN. :P ^^XDDDDDDDDDD

Ah, I thought you might have added in branding for those servers on there. also do you mind if I can host this on a public server?

You can see on the Screenshots what was changed from the orginal map. (I hope that wasn't meant as troll) It's the rooftops map that was changed to rooftops lost from another person, and i deleted a lot of bushes reskined all of the buildings edited teleporters and so on.
See it yourself. :P

What was changed from the origianl map? I wanna host roof tops on my server and I'd liek to know what is different

Yes the map build up on the CS:S-Textures.

does this need cs:s no or yes??
