ValveResourceFormat

NuGet GitHub API Docs

.NET library that powers Source 2 Viewer (S2V), also known as VRF. This library can be used to open and extract Source 2 resource files programmatically.

ValveResourceFormat.Renderer

NuGet GitHub API Docs

.NET library providing an OpenGL-based rendering engine for Source 2 assets. Standalone rendering of models, maps, particles, animations, lighting, and materials with physically-based rendering (PBR).

ValvePak

NuGet GitHub

.NET library to read Valve Pak (VPK) archives. VPK files are uncompressed archives used to package game content. This library allows you to read and extract files out of these paks.

ValveKeyValue

NuGet GitHub

.NET library to read and write files in Valve key value format. This library aims to be fully compatible with Valve's various implementations of KeyValues format parsing.

C# 
// Open package and read a file
using var package = new Package();
package.Read("pak01_dir.vpk");

var packageEntry = package.FindEntry("textures/debug.vtex_c");
package.ReadEntry(packageEntry, out var rawFile);

// Read file as a resource
using var ms = new MemoryStream(rawFile);
using var resource = new Resource();
resource.Read(ms);

Debug.Assert(resource.ResourceType == ResourceType.Texture);

// Get a png from the texture
var texture = (Texture)resource.DataBlock;
using var bitmap = texture.GenerateBitmap();
var png = TextureExtract.ToPngImage(bitmap);

File.WriteAllBytes("image.png", png);
