Hi Hui!
I don't know if this will help, but I smoothed the edges of the texture by setting the Alpha value in the underlying polygon to maximum in the edges ( and to minimum in the elsewhere ). This creates a smooth transition from opecity to transparancy. you will have to do this using something more low-level than multigen though.
Note: it looks great on the InfiniteReality but less than satisfing on my O2.
