Topic: Light Grid Volume tips, can it be too large?

Sorry I meant reflection probes. Basically I have created a huge map for our low gravity server, initially I enclosed the entire thing (about 30 stories high) just inside the light box and placed reflection probes just above all of the places players will land but nothing changed. I then tried putting smaller areas of the light grid volume just over the solid places in map where players will be running and playing with 4 light probes in each, neither of these configurations worked. This is why originally I asked if I was missing anything? Is there anything further I need to do besides placing light grid volume around the play area and adding reflection probes? I do compile lighting after modeling if you were wondering. What is the correct way to use light grid volume? I am not making the rectangle light grid volume hollow, could this be whats wrong? The only light source I am using is the sky box. Night vision also does not work when setup like this.

Yes, lightgrid can be too large. It only has so many sample points. You can check, or get an indication it is already too big simply when your map no longer updates. You can read the compile log, and near the end of the light compile it would say something like: Light Grid Sample Points Exceeded. Post your compile log if you are unsure. When your compile process completes. Right click your CMD window, choose, Select All, then press enter and it will have been copied to clipboard. You can then paste it here using the BBCode > code button. Code: Compile Log contained in this box. 1. Make sure your Spawn Points are enclosed in your "lightgrid_volume". You want the player to spawn inside the brush. The Lightgrid should NEVER be hollow. 2. Make sure your playable area contains "lightgrid_volume". It can be multiple brushes butt up against one another. Just as long as the player never leaves the brush. If the player does leave the brush, the shadows are no longer true "sunlight" and such. You will instantly notice a change in lighting the moment the player leaves the brush. 3. Technically, you can get away with only using 1, reflection probe in your map. Many times I work through 90% of my map using 1 probe and near the end I add more to fix all the lighting. However, if you want reflective surfaces to properly reflect nearby lighting, you will need to add other probes to compensate. Every time you add, move or change the properties of a reflection probe, Compile Reflections must be done from the tools. I did a map long ago that was way up in the sky. It had both ground playable area and an area way up in the sky. I had an issue with rainbow, and it seemed that no matter what I did, I could not solve it. Then I tried using the tools texture, "lightgrid_sky", but only up in the high part of my map, and it solved my problem. I made a conclusion that maybe the game, after a certain height, no longer can use "lightgrid_volume", but needs "lightgrid_sky" instead. Maybe you can try that in your upper areas of your map. It also depends on where you started your ground level on your coordinate structure. If you make the mistake and not start building on your 0,0,0, you may run into this issue on your own.

0,0,0 is in the center of my map, it sticks above it and below it evenly, unless there is a select all function in radiant I dont think I can fix it as it is too massive. I changed the light box to bloc worldspawn settings and the rainbow is no longer present. Night vision displays sthe same colors as without night vision, no change so can I assume this is also do to my light grid not working?

There is a select all function, I just don't remember what it is as I've never needed to use it. You can check the hotkeys, which is probably under the help menu. I don't think there is any reason to select all and move the map to another. I'm sure it is a simple fix once we figure out what it is. You can post your compile log and we can at least rule out that you haven't exceeded your light grid points, and or any other errors that is keeping your map from updating or compiling properly.

Select all is "i" key.

Lightgrid_sky tool texture solved that for me.

Too much Lightmap errors. You need to fix that. Select the patch you have lightmap error on, press Shift+L, then S, and LMap (or what ever you need to fix lightmap). Remember to check Lightmap every time you make a patch. Or what you can do is simply remove (prefabs / fallujah / bldgs / city_ construction . map) from your map.
