Creation of object groups from in-game objects that already exist

It is possible to make an object group from ‘rendInst’ that already exists in the game. This means that you will be able to place them directly from the mission editor (it will remain destructible if the original object was destructible). This is very simple to do - an additional folder named "objectGroups" needs to be added to the existing folder: WarThunder\content\pkg_local\gameData\ so WarThunder\content\pkg_local\gameData\objectGroups

A new file should be added to this new folder with a convenient name and the extension .blk (for example - patton_01.blk).

The new ‘.blk’ file should have the following lines written into it:

className:t="composit"
 node{
   type:t="rendInst"
   name:t="#studebaker_us6_bm_13h"
   tm:m=[[1, 0, 0] [0, 1, 0] [0, 0, 1] [0, 0, 0]]
   placeOnCollision:b=yes
 }

The "className" will tell us that it is an object of the composite type which has one node of the ‘rendInst’ type called “studebaker_us6_bm_13h” (can be changed to any object you want to). Next will be the object matrix and placeOnCollision parameter which allows you to always put the object in a ‘collision’ state (able to interact with other objects).

After these steps it is enough to put the corresponding unit in the mission and it will be visible in the game.
