Hello friends,

I'm new to the community and new to creating maps with Hammer, but long-time Portal player.

I've recently ran into an issue while using Hammer. Normal light entities within my map behave just fine, but as soon as I give it/them a name in its entities properties, they fail to reflect light off surfaces--or in other words, produce light on textures which are not their initial point of contact. I don't know if this is an accurate description of what is happening but it's my best guess based on what I am seeing.

I recreated the issue by having a light entity cast its light down a hallway and took some screenshots. The first image is a normal light entity without a name. The second image is what occurs as soon as I give that same light entity a name in its properties.

As you can imagine, this produces severe issues in my maps.

Here's the compile log for when the light entity is named:

And (if it matters) here's the compile log for when the light entity has no name.

My only theory is I goofed something up when I altered the compile run commands while following a tutorial, but I don't know enough about any of that to know what the problem would be. In any case, below is a screenshot of what that window looks like for me.

https://imgur.com/EY0ool0

That full line for the $light_exe reads:-StaticPropLighting -StaticPropPolys -bounce 2 -noextra -game $gamedir $path$file

Also, I've played around with checking the unchecked parameter but I've found no difference.

Any help here would be much appreciated! Thank you in advance, and I'm glad this community exists.

Hello friends,

I'm new to the community and new to creating maps with Hammer, but long-time Portal player.

I've recently ran into an issue while using Hammer. Normal light entities within my map behave just fine, but as soon as I give it/them a name in its entities properties, they fail to reflect light off surfaces--or in other words, produce light on textures which are not their initial point of contact. I don't know if this is an accurate description of what is happening but it's my best guess based on what I am seeing.

I recreated the issue by having a light entity cast its light down a hallway and took some screenshots. The first image is a normal light entity without a name. The second image is what occurs as soon as I give that same light entity a name in its properties.

As you can imagine, this produces severe issues in my maps.

Here's the compile log for when the light entity is named:

My only theory is I goofed something up when I altered the compile run commands while following a tutorial, but I don't know enough about any of that to know what the problem would be. In any case, below is a screenshot of what that window looks like for me.

https://imgur.com/EY0ool0

That full line for the $light_exe reads:-StaticPropLighting -StaticPropPolys -bounce 2 -noextra -game $gamedir $path$file

Also, I've played around with checking the unchecked parameter but I've found no difference.

Any help here would be much appreciated! Thank you in advance, and I'm glad this community exists.

Hello Nightro and welcome to the forums.

The act of lights emitting to other walls is called 'bouncing' and according to this page will not happen with named lights.
The only way round I can think of is to create another named light with the same targetname and toggle this on within the darkened room at the same time.

Valve uses env_projectedtexture for dynamic togglable lighting but also doesn't bounce (they also make the map size smaller).

There is one thing you can do (but it might be more trouble than its worth): teleporting the player between lit and unlit versions of the room. Valve did that on the Jail Break map (sp_a2_bts1) when Wheatley turns the lights off.

After all the tutorials I've absorbed, I'm shocked none of them have mentioned this, as it should be a basic behavior that results in experience-breaking eyesores. I'm also surprised that out of all the Source Engine pages by Valve I've read I haven't come across any that reference this until the ones you guys just linked.

Thanks to both of you for pointing this out.

I've actually done this, but I thought I was performing a ghetto work around for a glitch that others didn't have to. Now I know it's normal.

When you say, "dynamic" do you mean the env_projectedtexture can move? When parented I assume? Or does dynamic refer to something else?

That would explain why they have you walking on the lightbridge when the lights go out, to limit the variability of where the player is and thus make the transition more smooth.

Did they do it this way because triggering the lights to turn off would require naming the light sources and they had more than the amount allowed projecting on surfaces? Also, the dynamic shadows being cast in front of Wheatley during that scene would be created from the env_projectedtexture Chickenmobile referred to, right?

All your assumptions are pretty much spot on.

Dynamic refers to a light that is rendered after map compile, they can be moved / parented. They are generally expensive so only one of these lights can be active at one time. There are other types of dynamic lights but don't look nowhere as near as good. HL2 used a dynamic light to cast shadows for the flashlight.

To better understand what the rushed masters did to get round Source limitations, you can always decompile them and take a peek. I use a tool called BSP Source but there is also VMEX.
Maps are located within Portal 2/portal2/maps.
