Originally posted by I-Iybrid Howd you do the rain? Particles, or a movie projected onto a plane? it was a rain effect. When I rendered out the seen in maya I made sure there was a alpha channel that cut out the window parts. When I composited the scene I had the maya scene on the top layer, the rain effect on the next layer,then the background. I think I also multiplied or overlayed the rain effect layer and background so it blended in nicely. It was really simple actually.
