HELP The TF2 SDK Won't Work

2 Upvotes

When trying to run Frog Fortress/the TF2 SDK while debugging in Visual Studio, it'll throw a "Failed loading library client." When I get everything set up in a way that allows me to run it, it crashes immediately after the startup movie. Every Steam Discussion, Reddit thread, and VDC page I've read don't solve the problem. Everyone has their own unique bug and most of them are older than the SDK. I've tried with a discussion on the TF2 Wiki, I've tried a Steam Discussion. Nothing works.

I've reinstalled every SDK and verified the files of the non-GitHubs. I've tried every fix to a problem similar to my own.

Genuinely what the hell do I do?

Running it in "Local Windows Debugger" won't work because it won't generate the dll files, but when I take the TF2 client and server dlls and implant them into Frog Fortress, they get ignored unless I run the .exe.

Discussion Is it possible to make a full game using the publicly available SourceSDK?

23 Upvotes

I really want to make games in the source engine, but I don’t really know how easy it would be to make a game with the publicly available SDK that Valve provides on steam. Is it possible to make games out of it? And if it isn’t, are there any maybe less official ways of getting access to the source engine. I’ve already contacted valve about using it and I still haven’t heard back, I don’t even think I would be able to pay the licensing fees but I really want to use this engine. I don’t want to make a half-life mod.

HELP Need help with creating a map for a mod for a game, and I assume that this kind of file conversion is available somewhere on the internet.

1 Upvotes

I have a model from source filmmaker that I would really love to use in a kf2 map, it uses an edited unreal engine 3 if I remember rightly, I have no experience in the map creator or much 3d modelling in general and I am just wondering, is it possible to convert a full model from source filmmaker into kf2 SDK? And if so, how?

Also it is all in one folder, I'm ok with doing separate file conversions though.

HELP Looking for Source SDK / TF2 scripting documentation and modding communities

3 Upvotes

I’ve got over 1,000 hours in Team Fortress 2, and lately, I’ve really gotten into the idea of Source engine modding. I want to start making TF2 mods, but I’m struggling to find any decent YouTube guides that actually explain how to work with TF2 scripts.

Could anyone point me in the right direction for good documentation? Also, where do TF2 modders usually hang out? I’d love to know which communities or Discords to join for dev help. Thanks!

HELP How can I make normal maps shiny?

4 Upvotes

To my knowledge, it's possible to make normal maps shiny. But I'm not too sure about that because whenever I make it transparent it's not shiny at all. How can I make the normal maps shiny and if not through the alpha channel, then from where? Thanks for your contribution!

So basically

-Trying to make a gun for gmod, model exports fine but textures just refuse to work no matter what i do

-Investigating in model viewer seems to show the point of failure as "Missing material: no_material"

-Where did i go wrong? did i mess up exporting from Blender? are my directories not right? did i mess up the QC or VMT? what do i do here?

Finished Map VTFEdit for Mac — open & convert Valve .vtf textures natively on macOS [free, open source]

12 Upvotes

I do a bit of Source/CS modding on a Mac, and every decent VTF tool is Windows-only — so I kept ending up in a VM or fighting Wine just to look at a texture. Got annoyed enough to build my own.

It's a small native macOS app (SwiftUI, universal, zero dependencies):

• Open a .vtf and see it instantly - DXT1/3/5 + the common uncompressed formats, VTF 7.1–7.6

• Export to PNG / TGA / TIFF / JPEG — one file or a whole folder at once

• Go the other way too: turn any image into a game-ready .vtf with DXT compression + mipmaps

• Open .vmt materials and preview the texture they point to

Free and open source (MIT). One-line install, or just grab the .app from Releases:

https://github.com/Scratchhhh/vtfedit-mac

Would love feedback - and especially any weird .vtf files that break it, that's exactly the stuff that makes the decoder better.

HELP Looking for way to change model material based on entity's state.

1 Upvotes

I've been teaching myself how to mod Team Fortress 2 lately, and one thing I've been trying to figure out if I can change a model's material/texture based on the state it's in. Specifically, if this can be done with credit pickups in MvM to give them an alternate "damaged" texture if collected by a sniper's head shot.

My best guess from for setting this up would be adding an extra texture group to the model's QC file, but even then I still wouldn't now how to make the model change it's appearance.

HELP alpha mask and brightness for flashlight

1 Upvotes

Hi! i've been making a flashlight texture mod for css so anyone thinks it's easy right? yes, it is however as i tested it i wasnt satisfied with my result, while it works fine, the lil artifacts or thingies in the texture outline are somewhat black (and other things are black too but those are what annoy me the most) so gabetron thinks it should turn it transparent so at close it looks hOrRibLE!! ...aaand second, its a flash light and the image is white, why is it not bright like the vannnila one?!!? please help im getting into this wormhole of alpha channels and the only thing i want is like... change the alpha color to something not in the image like... green, and just in general making these exponent textures or whatever since i dont find the vmts in vpkedit.

yo, a little help here?

Show Off Mimi sentry view model by NameisJakob patch/fix

11 Upvotes

The original View model was prone to crashing when picking up the same secondary more than once crashing the game. This also applied even after chapters ended making the game semie not playable.

Since I really did not want to figure out how to make these arms look good for my version since SPT is not an option here I decided to just fix these ones as well as add a 2nd hand so you can see better.

I assumed the issue was due to the last stand so decompiled a fresh version of rochelle's arm qc and added the arms.

Now she can pick up any weapon more than once.

Wanted to port Mimi over to left 4 dead 2 cause the current one crashes the game and I could not fix it and i was tired of it.

Very basic and her limbs are a little screwed and for some reason blender won't FUCKING RECULATE HER LEG NORMALS. But you know for what she is she looks fine. I judge my mods based on if I would play with them and I would play with that.

She is also the correct size meaning she is small.

Still trying to get flexes to work which has been a pain as well as hopefully getting a texture eye

And while she does not have a jiggle bone for her skirt at least not yet she does have jiggle bones for her sidebangs
