This is how a normal render pipeline works for any WoW version (pseudocode).

So as you can see, the stars, planets, clouds and environment stuff is first painted, then the map ADTs are drawn, RenderMapObjDefGroups are WMOs and get painted after ADTs, then every liquid is painted, after that every M2 (Doodads) are painted too, and finally NPC/Players (RenderObjects) as the last step.

== Enables ==
== Offsets & Default Values ==
You should know that poking these Enables may crash your client, specially in early versions of the game (alpha, vanilla, tbc)
The flags are stored in 4 Bytes (= 32 Bits) at a static offset which differs every version.
Changing Enables may crash your client - especially earlier versions pre '''Wrath of the Lich King''' are prone to this.
The following list contains data in the format: [version], offset, default value


The following list of addreses can be used to find '''Enables''' in the mentioned versions:
  [0.5.3]
  ['0.5.3']:
  0x00A4046C
  renderFlags: 0xA4046C,

Where '''renderFlags''' is the location of '''Enables''' in the memory (WoW.exe + renderFlags) and '''renderFlagsDefault''' is the default value for that version, just in case you have to reset it.

Depending on the WoW version you may see a different rendering mode as none all modes are supported in all the clients. And in all years of development these have evolved for obviously reasons.

Revision as of 02:46, 28 April 2022

Rendering flags control how the WoW rendering engine paints the world onto the screen. We call them Enables, because that's what the reverse engineering suggests.

This is how a normal render pipeline works for any WoW version (pseudocode): 

Wow.exe-> StormStaticEntryPoint
 Wow.exe-> PaintScreen 
   Wow.exe-> OnPaint
   Wow.exe-> CGWorldFrame::RenderWorld 
       Wow.exe-> CGWorldFrame::OnWorldRender 
       Wow.exe-> CWorld::Render
           WoW.exe.DayNightRenderSky
               WoW.exe.GxSceneClear
               WoW.exe.DNSky::Render
               WoW.exe.DNStars::Render
               WoW.exe.DNPlanet::Render
               WoW.exe.DNPlanet::Render
               WoW.exe.DNClouds::Render
           WoW.exe.CWorldScene::RenderHorizon
           WoW.exe.CWorldScene::RenderChunks
           WoW.exe.CWorldScene::RenderMapObjDefGroups
           WoW.exe.CWorldScene::RenderOcean
           WoW.exe.CWorldScene::RenderWater
           WoW.exe.CWorldScene::RenderMagma
           WoW.exe.GxXformPop
           WoW.exe.GxRsPop
           WoW.exe.CWorldScene::RenderDoodads
           WoW.exe.CWorldScene::RenderObjects
Start rendering again

As you can see, the stars, planets, clouds and environment stuff is painted first, then the map ADTs are drawn, RenderMapObjDefGroups are WMOs and get painted after ADTs, then every liquid is painted, after that every M2 (Doodads) are painted too, and finally NPC/Players (RenderObjects).

Offsets & Default Values

The flags are stored in 4 Bytes (= 32 Bits) at a static offset which differs every version. Changing Enables may crash your client - especially earlier versions pre Wrath of the Lich King are prone to this. The following list contains data in the format: [version], offset, default value
