Light at the end of a tunnel

[Ardoramor]

I looked in the old threads trying to find how to make this effect but I found only one that was unanswered. I tried to make it myself by putting an env_sun entity at the end of my tunnel but nothing happened. Can anyone help me out with that? Thank you!

*bump* Please! I'm sure that I'm not the onle person that would like to know this. I tried is several times but nothing happens. Can someone explain it to me? Thank you!!!

Use lightglow instead.
Seriously.

Oh I never knew there was this entity! Thanks
