See [this] (https://www.reddit.com/r/Sourceengine2/comments/57ferg/features_of_source_2_developers_pov/) Reddit for a updated version.

There are already Threads about the features of Source 2, but here I want to collect especially the features (which are known or speculated) for developers. It will be updated whenever I find something new!

Generic Features:

  • 64-Bit Support
  • Support for DX9 and DX11
  • Support for Vulkan
  • Probably: Support for Mantle (you can find a string "RENDER_SYSTEM_DLL_MANTLE" in engine2.dll )
  • Support for VR
  • Free to use for "content developers" ( Source )
  • Probably: Importer for legacy Source 1 content (see source1import_blacklist.txt in Destinations)
  • Probably: Supports Bink Video, AVI and WMF (?)
  • Probably: Most of HL2 Entities and Classes exists (I created header files for The Lab demo, using this tool. Found HL2 classes in it.)
  • Supports Lua and probably Python for scripting
  • Probably: Support for "direct peer to peer connectivity" (Check out the help for p2p_* cmds like p2p_ping)
  • Probably: Support for "physically" clothing simulation, especially simulation of cloth behaivior in wind etc (see help for cloth_* cmds)
  • Probably: Support for day-night-cycle simulation and simulation of lightning on earth a like extra-solar planets with this model (Source 2 seems to use a example code of the researchers)
  • New GUI called Panorama (see [here] (https://developer.valvesoftware.com/wiki/Dota_2_Workshop_Tools/Panorama) )

Technical Changes:

  • New File formats (VMDL instead of MDL, VMAT instead of VTM/VTF etc...)
  • New Kevalue2 Format for Files
  • Use of DMX files
  • Probably: Revised Physics Engine (see vphysics2.dll) called Rubikon
  • Better support of dynamic lights (Dota 2: Reborn uses only dynamic lights)
  • Game Infos are specifed in gameinfo.gi not in gameinfo.txt
  • Compiled maps are a VPK-Package, not longer a BSP
  • Probably: Other access system for filesystem (Source 2 let you choose between "native" and "STDIO"

Development tools general:

  • A Assetbrowser which shows all your content of your mod
  • New Model editor
  • New Hammer Editor
  • New Console
  • New Material Editor
  • Probably: Integrated debugging tools for scripts like adding watches, breakpoints and attach a debugger (see cl_script_* cmds). Maybe there will be some type of an official scripting IDE/plugins for existing IDEs for source2, there are hints for a help function with support for auto-completion
  • Probably: Tool for working with sounds (check "sndtool_help.txt" in core/tools/help )
  • Probably: Tool for creating/editing help files (check "helpsystem_commands_help.txt" in core/tools/help)
  • Probably: A tool for creating post processing effects and a tool called "PlantToolApp" (see files in core/tools/keybindings)
  • Probably: There are hints (in core/tools/images) for tools with name "workshopadmin", "grapheditor" (maybe this has something to to with clothing), "revison_control", "portraiteditor", "propertyeditor", "snooper" (maybe something with physics) and a new faceposer
  • A scene debugger (see plugin in "SteamVR Performance Test" VConsole)

New Console (Console2):

  • Starts a seperate Task and Window (no longer ingame)
  • Supports remote control (?)
  • Support for plugin like things
  • Support for Tabs
  • Engine sends its messages on different channels, you can filter for messages from a specific channel
  • Each Message has a priority level, so you can filter for important messages like errors etc.. (like in android ADB)
  • Better syntax completition

New Material Editor:

  • Lightning preview for Materials
  • Supports importing bitmaps from PSD (Photoshop format)
  • Shaders supports glossiness and metallness maps

New Hammer Editor:

  • Working ingame Lightning Preview
  • Faster/Improved 3D Preview
  • Importing feature for VMF files (Maps from old Hammer)
  • Written in QT4 (So maybe the workshop tools will be ported to Linux/Mac)
  • Undo-History
  • Support for map global variables
  • Internal Screenshot Function
  • Uses the old FGD Format (?)
  • Moving and Transform functions for Brushes are now more like in "real" 3d modelling Programs like 3DS Max. For example: You can specify the pivot Point of a brush
  • Tools for Modeling Brushes inside Hammer. For Example you can work on Vertex or Edges Layer and can do things like extrude or bevel Edges
  • Asset Sprayer: You can easily "spray" asset preset, like for example a road or a forest on your map, this makes it easier for players to create maps. (used for example in Dota 2)
  • New Chooser for Models and other Assets (Asset Browser)
  • light entity renamed to light_omni
  • Map size is no longer limited to Grid size
  • Maps dont have to be closed to work

  • "Dota 2: Reborn" Workshop Tools available
  • "SteamVR Benchmark" - similar to "The Lab"

If you have something to add, then post it, and I will update this post.
