After looking at so many images with sun rays coming in through windows,doors or openings in walls and roofs i thought i would try doing something like that. At first i looked at Rochr's tutorial and thought ok, easy for him to do so why can't someone like me do it. Here is what i have so far, quick render so i could practice the sun beam/s

I have opinions of my own -- strong opinions -- but I don't always agree with them.
