** See [[HDR Lighting Basics]] for information on how to add HDR to maps.

** HDR content creation is currently supported in:

* A game configuration is created if DoD:Source is installed.


=== New VGUI model browser ===
[[Category:Valve]]
* VGUI Model browser with substring filtering, 3D preview, and reference grid to indicate the size of the model.Camera controls are:
{{Source topicon}}
** left mouse: rotate
[[Category:Source SDK FAQs]]
** right mouse: zoom
[[Category:Entry pages]]
** middle mouse or SHIFT: translate
[[Category:Changelists]]
* Added option "Use VGUI model browser" under Tools->Options->General. Unchecking this option reverts to the old model browser.
 
=== 2D and 3D View enhancements ===
* Models and Displacements are now rendered in the 2D views.
* 2D views are now rendered using the Source material system.
* Added new toolbar option to enable model rendering in 2D views.
* Added real-time preview of object transformations in all views. Old state of manipulated object is drawn as wireframe, new state as textured.
* 2D views now center on selected objects after view type switch.
* Optimized 2D view rendering.
* Hammer now renders 2D and 3D views only on demand, not as fast as possible.
* Added new "Shaded Textured Polygons" 3D view mode to hammer.
* Hammer disables antialiasing by default.
 
=== Auto Visgroups improvements ===
* Added many new Auto-visgroup categories.
* Created a separate tab for Autovisgroups in the Filter dialog.
* Disallowed users changing Autovisgroup membership, deleting Autovisgroups, etc.
* Objects that are loaded in a hidden state without being in a user visgroup will throw an alert message and ill be placed in a User visgroup named "_orphaned hidden".
* Objects hidden by a user-created visgroup can no longer be made visible by the actions of the auto visgroup.
* Filter dialog is now resizable when undocked.
 
=== Paste Special Enhancements ===
* "Make entity names unique" appends numbers to pasted entity names to ensure that the names are unique in the map. Doesn't change the name of entities with no name to begin with.
* "Add this prefix to entity names" adds a user-defined prefix to all pasted entities that have names.
* Both of these options fix up I/O connections and inter-entity references, and the options can be used independently of each other.
* Paste Special is now invoked with Ctrl-Shift-V.
 
=== New Autosave feature ===
* Autosave options are located in Tools->Options->General:
** Time between autosaves in minutes.
** Amount of hard drive space to use for autosaves in megabytes.

* Added a button for Texture Lock While Scaling to the tool bar.
* Overlay scale operation now supports texture lock off.
* Optimized speed of Paste & Clone operations.
* Selection tool no longer toggles through objects when holding the left mouse button down, use PageUp/PageDown keys instead.
* Check For Problems now reports Overlay problems, such as overlays with invalid face lists.
* Hammer now reports its Steam search paths in the Messages window on startup.
* Can no longer have multiple instances of a map open in hammer. Fixes user confusion regarding which map is being edited causing data loss.
* Find/Replace dialog now allows you to change the inputs mid-search.

If you see this page when you first open the "Source SDK" (AppID 211) launcher, please note that the standalone Source SDK tool/launcher is no longer updated, and does not support Source 2013 and Team Fortress 2 branch games.
The deprecated Source SDK tools are provided to create content-based mods for Source 2009 or earlier, and to obtain source code & create or maintain legacy mods built on Source SDK Base 2006 and Source SDK Base 2007.

To launch the SDK applications (Hammer, HLMV, etc...) manually on Source 2013 games, see the SDK Installation - Source 2013 (SteamPipe) & TF2 branch section for a list of applications and their executables.
