I don't know what has happened, the last three times I have compiled my map I have gotten nothing but rainbow colored models. I know that without a grid file that this happens. But I have grid files, I used the lightgrid_volume texture as well as the sky one as well. I have made any changes lately should affect this. I just added dm spawns to my map.

Do you have at least one reflection probe?

Can't a leak in the skybox cause this as well?

like PC said add at least 3 reflection probes to your map, 6 ft or so off the ground and the rainbows should go away

hmm post didnt make in the thread somehow.
I have over 30 reflectors in my map.
Double checked no leaks in the sky box.

scartching my head on this one.

you need to create a grid file for the map. In compile tools there is a selection to do so. This should fix your error.

According to the wiki, you can either create a grid file "The hard way" collecting the dots. Or the "easy way" using the lightgrid_volume texture along with the lightgrid_sky texture and let the engine calculate the light grid itself. This is the method I chose. My grid files are getting generated durring the BSP build, so I don't think thats the issue.

ok, just finished another full compile. Still have the saem problem.
Double chekced my reflections probes, 32 to be exact. There is nothing intersecting my skybox. There are no leaks.

I think my next steps is spend the next 3 hours running around my map collecting the dots trying to do it "The hard way".

Anyone else have a better idea?

Add an object, any object, to your map. Compile it and run. See if your map is actually updating. If the object is not there, check around in your map for something called "misc. model" and delete it.

Thanks, hadn't thought about that. I'll check it out.
