God Light Rays effect?

[Asuyuka]

This is driving me up walls =/

If someone could, can I please have an explanation how to get those awesome light rays, you know, like in the pics where you see the sky and those giant beams of light shining through?

I see them a lot in the desert here on sunny days with a lot of overcast, kind of fallen in love with em.  So yeah, it'd be nice to know how to do them, thanks.

Small cloud size is the key, thickness higher than 8, sun strength of 500-800 or something like that, although it depends, increase glow power to whatever looks good.

3d clouds make it easier, but increase render time a lot, and often have bad looking areas unless you play around with them a lot.

The key parameters to get the sunrays visible are Atmosphere Accuracy, Cloud size and Metres point spacing.
