Some blender transitonal questions!

Hi im a student studying computer arts and Im working on an non photo realistic game project whitch emulates traditonal art stiles. I have been making everything in blender 2.49b using the game engines logic bricks. http://alshonours.blogspot.co.uk/ I have used unity a little in the past and managed to get a few games together but cant figure out how to do some stuff in unitu that i can in blender yet.

these are: Use displacement maps to make the mesh wobble.[seen here] http://alshonours.blogspot.co.uk/2012/10/happy-halloween.html

shadow masking. (replacing the area whitch should be shaded with a different texture) [here] http://alshonours.blogspot.co.uk/2012/11/another-cross-hatching-test.html

2d filters (but i know this is just a unity pro feature)

Can someone please point me in the right direction of tell me if the dobbly lines and shadow mapping are even possible in unity .

Thanks Alastair
