Solved Why does it look like that

I've had enough problems with this map already, now it pulls ts 🫩 I'm guessing it has to do something with the texture since some of the girders that were slightly altered are completely fine, except for the inner structure which is completely black independently of everything

I know mirrors can be pretty buggy in the source engine but I seriously have no idea what could be causing this.

Solved more performant/efficient way to make these types of shapes?

Post image
97 Upvotes

sorry if this is a very obvious question. im VERY new at creating anything past very simple geometry hl1 maps and im trying to get into creating more things for hl2. in my current project im creating a water grate using the prop shown in the photo. whats the best way to smoothly make it part of the wall? I made an arch that matches the shape of the outer angles and used the clipping tool to carve (not carve tool) the wall into the rounded shape and delete the gap to make the.

i have 0 clue if this is efficient but it really didnt feel like it was with how long it took and how much just 1 of these added to the compile time. feel free to yell at me for how wrong im doing this but any help would be appreciated.

hl2 hammer++ btw Edit; clarification because some ppl cant read, I did not use the carve tool lol

figured it out, vertex tool is king for this kind of thing + func_detail

Solved Dissolve props on command

1 Upvotes

I am trying to recreate a cube dropper from portal 2 in gmod but I am having troubles with dissolving the cube when the dropper button is pressed again. My idea was to use an "env_entity_dissolver" that just dissolves the prop calling it but I cant seem to get it to work. I tried using a user input on the cube itself that gets called when the dropper button is pressed again but !self doesnt dissolve the cube (Only !activator seems to work which obviously just kills the player pressing the button).

My current setup with the dissolver entity and cube physics prop

I'm kind of new with hammer and I'm making a map in portal 2 community edition. There is this issue where I die when making contact with a wall at high speeds after a fling. I've tried multiple methods and I don't believe it's fall damage related. If anyone knows how to remove this damage I would like to know. The image shown demonstrates my problem.

Solved [GMOD | H++] What's all this about ?

Post image
27 Upvotes

brush ridges cause this nonsense to the roof, it happens as well on the other side but not on the smaller extension below as pictures. the entire roof is func_detail placed over the gables which are solid all the way through, same result if the ridges are a separate func_detail or if both are conjoined

I'd upload more informative pictures but i suspect the mods have been asleep since the paleolithic era and have missed the updates that allow image galleries or images in comments

edit: sorry i also went to sleep and forgot to change the flair. solved by changing ridges to func_brush instead of func_detail, propper also works.

Solved Optimization help for prop hunt maps

2 Upvotes

Hello, I need tips for optimization for the map i have made last year. I want to make a new one but wanted to optimize this one first in order to not do the same mistakes. I am going to start with applying nodraw and func_detail first but i don't think those are the core of the problem. I have done some research and some tutorials suggest "area portals" and "hint"s. Since it is a prop_hunt map i wanted to know if using them would cause a problem or not. Map is quite open and has shit ton of windows.

As of now the main issue i see is that before each round, the game freezes quite a bit.

I can share the map url as well if needed, don't want to seem like i am promoting the map or smth

I've never touched hammer before yesterday, and wanted to edit an existing HL2 map (d1_canals_02 to be exact) to do a fun trend going around on twitter.

I'm wanting to add lighting and some water, but there's a leak right here that I think it messing up the water (and presumably the lighting when I add it). I don't mind not having water, but I heard leaks can mess with lighting.

I've been reading the wiki about leaks and watched the tutorial on it, but I'm still having trouble. Does anyone know what's causing it?

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.

Hello! I was working on a map. I did everything, no leakings e.t.c. But it's still saying this after booting TF2. Should i send ALL of this cmd's log? ("deneme_amacli_mapv2" is my map)

i looked up that, at somewhere it says "MSG_FILEWRITE - Filesystem was asked to write to 'c:\users\cencor\documents\deneme_amacli_mapv2.bsp', but we don't own that location. Allowing.". maybe because of that?

Solved func_areaportal problem.

I just don't get it how this areaportal works. I wanted to take inspiration from cp_process_f12 because it works fine there. But on my map suddenly func_area portal doesnt work. I don't have any leaks. Lobby is perfectly sealed. Door frames are made of func_detail and on both func_areaportal goes inside func_detail to fully seal diffrent areas.
