After you enable the DVAR 'cg_drawThroughWalls',
you'll need to find the code which checks cold-blooded is being used, then set the values to 0x90, 0x90.Code:0x3ED380+0x10 0x3ED380+0x20
Then the nametags, which has pointers like 0x27 etc (you'll notice it once you do a pointer scan). Set all those values to 0x90; same applies to things like chopper box ESP.
Good luck and have fun
EDIT: Please note that it's meant to be an AoB scan if you're using CT, if you're not making the program in c++
