Yes, it is. And your scene lagged my computer a lot btw

levithelegendary -- DANGA is right about this scene causing a lot of computer lag. As a suggestion, you really don't need 144 lasers to make an interesting refraction effect. I got good results by removing 100 of them and then I stretched out the remaining ones and increased the beam size of each laser. The resulting refraction pattern actually looked really nice! Try it!
