basically I'm making a weird map, and in area of the map, there is a func_door that moves out of the ground and comes up, basically turning from being a floor to a wall, but when I compiled and played the map, the func_door just kinda was pitch black,

any advice on this matter, like how to fix it?

So, I'm trying to make a map where you need to "pick up" 2 items so that you could open a door.

This is the setup:

A door with a multisource entity as its master

2 invisible func_buttons around 2 func_wall_toggles, both func_buttons trigger different multi_managers. These multi_managers have 2 functions. 1: trigger the func_wall_toggles so that they disappear making it look like the player picked up the items that the wall_toggles looked like and 2: Trigger a multisource entity so that the door would unlock when both func_buttons are triggered.

And also an env_global so that the multisource would work

For some reason the multisource is refusing to work as a master, it is getting activated, 'cause if I give it a target (like a light or something) the target gets activated, the problem is that it isn't working like a master ie unlocking the door.

I've quadruple checked that everything is named right, and such. So could somebody please tell me what I'm doing wrong?

I'm plannying on making a map where you'll gear up and go a whole session underwater, so is there a way to give the player unlimited oxygen? Not for the whole map tho, just a smal part.

Inspired by my love of industrial megastructures. Let me know what you guys think.

yes, i know the lighting looks crappy, it’s on the cheap lighting in this video, and I haven’t gotten to assigning lighting_info to some of the static props aswell

sadly cant add more photos

My new personal best for finishing and uploading a map is around 3 hours, it was pretty fun trying to get it finished as fast as I could! The map is called ttt_wildwoods, here's the link

I was hoping to make this area, which is meant to be resemblant to the Chernobyl Reactor 4 (Without Sheild) as it is the Galdos Chamber after it blew up. I already finished adding in all of the props in the Glados Chamber from portal 2, I just need to figure out how to...

1. Make the area look more destroyed on the surface

2. Make the Walls of that particular warehouse look blown out (One plan I have is to convert the walls into displacements and then add in props, but that sounds incredibly messy)

3. Make the surface covered in debris, parts of Glados all over the parking lot

But one issue I have is that once I playtest the map, no future changes will take effect. So, does anyone know how to fix that?

(Tf2) whenever i open it it just shows the face edit sheet (for some reason?) for like a couple of frames and then shows the hammer splash screen before just closing

So, I've been thinking. Personally, I think TF2 has too many symmetrical maps, I know it's for balance reasons as an asymmetric map can give one team an unfair advantage over another if it's not structured correctly, and I'm wondering; how can I structure an asymmetric map that's built to give both teams the same exact advantage as one another? It can be for any game mode, not just Capture the Flag, given that CTF maps are more difficult to structure in an asymmetric form. Other options include King of the Hill, Control Points, Payload, just to name a couple. Any ideas on how to make a map asymmetric for pretty much any game mode whilst still keeping the game balanced for both teams?

I started working on a Backrooms map for Garry's mod. This is the test map to test the textures I imported for it. I just felt like showing off the test map cuz why not! I'll probably share progress on the map as I go on here!

Also if you guys have any idea on what to add to the actual map, I'd love to hear them!

I made a bench and placed two prop_vehicle_prisoner_pods so players can sit on said bench, but the seats either get flung away, or get lodged into it like in the second picture. Is there a way to freeze or prevent the seats from moving? I thought about parenting it to an invisible func_detail or something, but I feel like there's probably a better option. Any help would be appreciated.

I'm adding a lot of stars on the ceiling of this map, and i wanna add them in a few different sizes, but
HOW does one resize an overlay

so tying to run the map doesnt work at all and just gives me an error. i have to open gmod and join the map to acces it. and for some reason its stuck in fullbright even tho i have a light_enviorment + directional and normal lights. i have no idea what to do this is my second ever map ive made and i cant even try to build anything because everything i do creates a new problem of its own. a

anyways heres the log

I am wondering if anyone knows a website where I can download .VMF's/pre-made models and assets whether custom made or directly from source games? I am wanting to extract a detailed ceiling found in css_office (for example) so that I don't have to spend a long time working on recreating it? Sorry if this is a dumbass question NEW TO HAMMER

I know the change might minimal but i was wondering if it helps with either fps or with compile time

I been working on his map and randomly it seems, the brushes are desponding even when looking at them? now it seems the cause of this is the Func_Detail brushes as turning them off seemed to fix the map, how do I have my Func_Detail brushes and not have the map explode?

Im quiet new to hammer source editor and ive never had this error before, maybe im just understanding it wrong but i have no idea on how to fix it, ive searched all around but everyone has different errors and i couldn´t find mine. if anyone wanna take a look click here: https://drive.google.com/file/d/1WBBHVGQaWgpmaMFTk7K5ayFUSIwovY5x/view?usp=sharing

Edit: I Solved it! i just turned the shelves,beds,sinks etc into a func_detail
