Sun/Shadow Effect (lighting) Created 17 years ago2007-07-16 01:46:21 UTC by ip

I've almost done my map, and I have one final touch I'd like to add to it. I'm trying to get it so that my light creates shadow effects behind objects. During the construction of my map, I'm almost positive that it use to create shadow effects behind brushs, but now it just lights up the entire map. In odd corners, completely blocked by the light, the area is still bright. I'm using a light_spot, set to 'is sky'.

Any help please on how to do this would be appriciated.

Does it have a pitch set? Try -45 or -60 (my personal favorite).

on your light environment or light or light_spot there is pitch. this regulates the shadows, have a go with that. If your too lazy then try the pitch on something like -35, but it depends on how much shadow you want.

Edit: argh srry.... your fast

And it doesn't "regulate the shadows", it's just the angle the light is coming off the sky. There's always shadows if it's not fullbright.

Still,I don't think the pitch is really your problem. It sounds more like a compiling thing to me. Did this just start happening?

Never use a light_spot to light the sky, use light_environment instead. A light_spot will light any models(and is especially noticeable on view models) with the sky lighting from the previous map played. This can cause series visual issues, especially if you just finished playing a map with green lighting(IE Xen), and your map is supposed to have white light.
with You probably haven't caught this yet because you haven't seen your map in a map cycle.

Strange, it's been suggested often here that the light_spot entity is superior to light_environment in terms of lighting quality. I never noticed a difference, but figured somebody knew what they were talking about and just did what I was told. Does this same problem afflict regular single player maps?

Somehow i think he has a leak, not a lightning issue.

Srry: Most likely. I've never mapped more than one continuous SP map with differently colored light_spots for the sky in each. But the likelyhood of that scenario in SP is so slim, whereas with multiplayer you are prety much guaranteed that scenario.
And you're right in saying that a light_spot delivers higher lighting quality than a normal light_environment, because a light_spot applies model lighting relevant to the light's position(as opposed to just taking the light level of the world under it) and its not so uniform. But if the lighting is all off in the first place ecause of something as simple as a map change, that special lighting doesn't look so special, you know?

Ok, I've tried both light_spot and environment with a pitch of -60 (I originally had -90, so it was always facing down) and I'm still not getting any shadow. I have no idea how to make a map full bright... I have no leaks, and here is my compile log:

Everything seems to be alright in the log..
Post your .rmf in problem maps.

Ok, here the link:

http://twhl.co.za/mapvault_map.php?id=4717

Is your light inside of something by any chance?? like if the light_environment is INSIDE a brush it won't light anything.. just a thought

Could be related to you putting 2 layers of sky-brushes around your map. Remove the outer sky-brush-layer and you'll end up with a leak, seal it and the problem should be fixed.

Okay, I'll try that right now, also I added the extra 1 pixel layer above the walls because people could jump up and sit ontop of it..

would changing them to clip brushs work?

@tetsu0: no the light is well spaced from any brush.

EDIT: So far its not working... :

You've turned almost your whole map into func_wall, that's always a bad idea...

Note that brushbased entities (doors, trains, buttons etc and func_walls) don't cast any shadows...

Ah I see, thank you.

Also entities do not block VIS, but they do not split faces either since VIS sees through them...http://www.cryotank.net/maps/tutorials/rspeeds2.html
