OK, managed to get most of the SIEGE stuff set up over the weekend. still have to draw the icons and map (just using temp stuff for now.), but all the teams/classes are working (with much tweaking needed for them I imagine). I've also started doing the lighting, though that will take a while.
I managed to get the shader working where it places models on the surface of the shader, so there are now ferns dotted all over the landscape. It looks OK.
Now I just have to get the objectives to work!!!
