you see in the second picture I sent you, where it says scale to (0.824), that’s the size, that’s the first number (x) that you put in the code then, the rest of the number that are on top (59 -29). Altogether would look like this:
EXT. WALL - NIGHT with GRENADE to 0.824 59 -29 in zone 1 at layer 1
Note: That is using the values of my picture!!
thank you
No problem!!
