There are 2 ways to do this. You can use the enters from command to the spot, but the character will enter the scene at the default size of 1.280. Or you can spot them offscreen to the left with the size you want them at, then make them walk to that spot onscreen.
@CHARACTER enters from left to spot 2.293 170 -520 in 2
or
@CHARACTER spot 2.293 -160 -520
@CHARACTER walks to spot 2.293 170 -520 in 2
