- Source 2 comes with an integrated development enviornment (IDE), consisting of: -
- Asset Browser, Level Editor, Material Editor, Model Editor, Particle Editor, and Film Maker. -
-

- Asset Browser

- The Asset Browser allows quick searching, previewing, grouping, and managing assets. -
- It also serves as the hub for development, launching the other tools either by their icon, or by double clicking an asset. -
- Assets inside the browser can also be dragged into other tools (such as Hammer). -

- Hammer Editor

- The Source 2 Level Editor (Hammer) is a revolutionary leap above even contemporary level editors. -
- On top of the expected brush-based manipulation, you can edit individual faces, edges, and even verticies, making it a full model editor. -
-
- The new primitive in S2 is the Mesh, a vertex-based system, allowing concave, and complex geometry to be authored by the level designer. -

-
-

- Meshes can be exported for further editing in 3D applications, and then re-imported as DMX, OBJ, or FBX. -
- Legacy Source VMFs can also be imported. -

- -

- Material Editor

- No more fiddling with text-based VMT files, slow material reloads, and trial & error debugging. -
- S2 MET Supports realtime editing and previews, with in-editor texture importing. -
-

-
-

- MET Also supports extensive dynamic functions, and the following image formats: PSD, TGA, TIF, PFM, MKS, PNG, JPG -

- -

- Model Editor

- Model viewer, and editor. No more fiddling with QC files, this does it all. -
- Used to configure hitboxes, collision, poses, weights, LODs, animations, constraints, attachments, and anything involving models. -
-

-
-

- Model Importing supports the following formats: DMX, SMD, FBX, OBJ -

- Particle Editor

- PET is for editing particles -

- Filmmaker

- The Filmmaker is used for rendering high-quality cinematics from in-engine. -

- VConsole2

- Vastly improved over the simple in-engine console of yore. Using a networked API for engine communication it allows remote debugging. -
- VC2 also features multi-tabbed displays for multitasking, extensive filtering, and verbosity control. -
