I was playing halo combat evolved and saw that the suns rays disappeared when they were covered by something. so I tried to duplicate the effect and this is what i got.halo sun.blend (611 KB)
hmmm…this is interesting that it was done with logic bricks only. A very primitive solution! But hey if it works for you, then there is absolutely no problem with it XD
Interesting idea, give it some textures and your good to go:D
