How To Upload Maps To Gmod

Please 𝓀𝒾𝓃𝒹𝓁𝓎 GӨ П FЦᄃK YӨЦЯƧΣᄂF

This guide merely covers uploading a map, with no custom content shipped with it.
For that you need pakrat, and that'south easy enough to employ, but do note it has the tendency to break maps occasionally, so don't trust information technology fully.

Creating addon folders

[1]Go to your desktop, create a folder. I will be referring to information technology as 'the addon binder'. From hither on out, most folders and files names aren't customizable.

[two]Inside of the addon folder, create a new folder, proper name it 'maps'. Paste your bsp in the maps binder.

[3]Forth side the new binder, not in it, right click>new>text certificate. Phone call the text certificate 'addon'. practise not modify this either.

[4]If you want a thumbnail that appears in the singleplayer card, create a new folder in the maps folder named 'pollex', create a .png file with the same name equally the .bsp file and place information technology in this folder.

[5]Create a new text file in the addon folder by correct clicking the inside of the folder, new, text document.

[6]Inside of the text file, write {LINK REMOVED}this, irresolute the championship and tags every bit they apply. (Alt link {LINK REMOVED}here )

[7]Click on file, Save Equally, change the salve as type nether where you type the proper name of the file to 'all files', and type addon.json

[8]Make a 512x512 JPEG paradigm to exist the thumbnail for your map, naming information technology anything you'd like. So motion the JPEG to the desktop, not into the upload folder. Also it tin can be any size yous want as long as its even (I call up, id practice 128,256,512 to be safe.)

Gmad

[1]At this point, your folder should look like this (roughly):

[two]Open the garrysmod directory at "C:\Programme Files (x86)\Steam\steamapps\common\GarrysMod\bin"

[3]Scroll down to gmad.exe, drag the addon folder on top of gmad.

If information technology appears and closes immediately, with blood-red text and no gma appears on the desktop, retry this guide from hither up & refer to the errors department commencement entry.

Gmpublish/command prompt

[1]Motility the JPEG motion picture to the within of upload, forth side the gma.
(i rename the gma file cause it looks nicer, I seriously dubiety its impact on anything.)

[]At present your binder should have:

[1] Maps>testmap.bsp
[2] testmappicture.jpg
[iii] testmap.gma
[four] addon.json

[2]Click commencement>type cmd>correct click>run equally administrator. Its non admittedly necessary to run as administrator, just there's a expert chance if you tin can't practice that, you cant write to the garrysmod directory.

[3]If your game directory and your Os directory is on a unlike drive (E: & C:, for example), and so earlier you access each drive with each CD command below, you must type the offset letter of the drive followed by a colon, ex "E:" before cd E:\.. or "C:" before cd C:\..
cd C:\Program Files (x86)\Steam\steamapps\common\garrysmod\bin

Change the (NAME) to your login name.
gmpublish create -addon "C:\Users\(NAME)\Desktop\upload\testmap.gma" -icon "C:\Users\(Name)\desktop\upload\testmappicture.jpeg"
If your file is named testmappicture.jpg, change this file extension to .jpg.
If successful, this will take a few minutes depending on the size of your addon.

[iv]If at that place is scarlet text on the command prompt says your addon is individual and then information technology is uploaded, and so it is not visible to the public, only is visible to steam mods, apparently.

[v]Get to steam, hover over your name at the peak, click 'content', click workshop items, click your addon, scroll down until you see visibility on the right, click the drop down pointer and click public.

Ensure you accept agreed to the steam workshop rule matter, it should be an orangish bar at the top of the addon page. When its public and you accustomed the rules, anyone can download your map to play.

Updating the already uploaded map

[1]Very like to how to publish it, open upward Control Prompt and type cd C:\Program Files (x86)\Steam\steamapps\mutual\garrysmod\bin

[ii]You lot need to get the ID of your workshop item to update it, open up steam and hover on your name at the top, get into content in the drop down, click workshop items, and click on your map. when yous're on the workshop page for your map, it should say in green text at the top of the page that should say something like https://steamcommunity.com/sharedfiles/filedetails/?id=1111111111. Where it supplant the (ID) in the command with this number. It must also be public to be updated.

[iii]Then type gmpublish update -id (ID) -addon "C:\Users\(Name)\Desktop\upload\testmap.gma"

Common errors:

Gmad appears for a split second and closes

Y'all have to hit print screen right when it comes upwards to read it, or record it and break the video when it appears. Read the error and go from in that location. Welcome to the source engine.

Could not open the map icon/gma file something like that, in gmpublish.

This is a catchy error, often you don't know what you did to set up it, why it fixed information technology, or how you'll ready it side by side time.
[1]Yous can try to resave the file in paint, overwriting the quondam file.

Open up your paradigm in an image editing software, such equally paint.
Click File>Save
Pray

[ii]You can likewise try saving it every bit a .jpg instead of .jpeg, sometimes that works. Ensure you lot change the -icon directory for control prompt to say .jpg if you exercise.
[3]That, or the directory to the epitome is wrong that yous typed into command prompt.
[iv]This happens for the gma too, except for the gma the directory is wrong, and is relatively straight forward.

(file) does not pass whitelist

Ensure you just take the files i said to put in upload, any others will whitelist everything. There is a few other things you tin can include in your addon, such equally lua, and custom textures, models, and sounds. Wouldn't it be lovely if this was how you lot included custom content in your map? Doesn't piece of work, for whatever reason.

Fault (finding) json file

For gmad, the directory you told the command prompt is wrong.

Couldn't parse icon/json

In that location'due south something incorrect with your json file. Ensure its correct, I suppose?
If yous cant parse the icon, I honestly forgot why it happens but similar you ♥♥♥♥♥ upwards the picture brand sure its 512x512 pixels and like its non png or something

Don't have permission to update your addon or some ♥♥♥♥♥.

Incorrect ID number in the control, or not logged into steam.

Error opening addon (does this file be?)

Wrong file path in the command line to the .gma file.
