appearance of monsters

How do you change the appearance of monsters? because when im mass spawning oread, it lags a lot and if ppl come by, i cant click them to invite them to the party.

I figured out how to change the appearance of the earth hatchlings to a blaverus but the size still remains the same so it just looks like a distorted blaverus and yet it still lags.

What im trying to do is make the hatchling look small and like a blaverus, could someone help me please?

The only way I know to do this is with CSV editing. Go to 2Moons\data\share\creature\monster.csv

Colomn AC is shapeinfo. I think if you change the hatchling to whatever the blaverus shapeinfo is, it will work. Not positive, since I've never actually tried this before, but I'm fairly certain that that is how it's done.
