Point Light with Shadow Casting

[Alex Ros]

Well, technically, you can create a similar effect by combining 6 spotlights 90 degrees each into a cube shape. You will need to create a new gobo for it, though.

I tried that in the first place. And it doesn't work out well. There were glitches and flickering.
And by the way for that Point Light with Shadows I don't need gobo.
