I've PM'ed you a link to an example WAD.

Try firing rockets, BFGs or plasmas to the wall with the god rays. The two 1-sided walls beside them light up; but the 2-sided wall doesn't light up.

It's your texture. Dynamic lights don't work on textures with an alpha channel that contains other values than 0 and 1. Sorry, that's not easily fixable. To do dynamic lights on two-sided walls I need to mask the texture and this isn't possible here. For normal textures it is just a few GL state settings to render a mask.

Oh, I see. Well no big deal - I don't have any problem with the texture having simple transparency.
