Gildor,
The only problem with that is that it may limit the size of the building, unless you use a morph skill which allows you to resize. Then again, if you mess up and put something near it that won't allow it to expand, then the morph will fail.
wciow,
sorry for the misunderstanding. I didn't model anything (hehe), I just played the 1st part of the Guard's dying animation. Also, I figured out that I only need 9 frames for each tree, one in the center and one frame with it pulled in one direction or another. Then I can morph between the different animation frames (will take some code mods I'm sure).
Botjer,
I completely agree on the effects, dust, smoke, flying leaves, debris, sticks & stones, I'm 100% with you on that!!
