Please Help....An issue of lightmap in making custom map...

[Nyon]

I just made a map with the source2 Hammer and everything seems pretty fine when running the map from the hammer.

But when I try to run the map in the addon list from inside the HLA game, the lightmap is broken and everything goes dark.

It's really annoying and I try everything but it is still broken.

Would anyone happen to know how to fix this...? I'll be appreciate it :)

I tried to full compile and it fails. Showing that "

I've been using fast compile and everything was fine. It seems that the lightmap wasn't built at all. I just knew that the hammer version runs in VRAD2 which doesn't need lightmap.

But I'm now having trouble to find out what's causing this "OUT OF MEMORY" now....Will leak or anything like too many lights cause such issue..?

It seems to be running out of memory when packing the UV map for the lightmap texture. Unless it's bugged, the amount of memory it uses would probably only rely on the amount and complexity of the static models and meshes in the map.

This doesn't seem like a step that would need that much memory though. Maybe check that you don't have anything else eating up all the memory. How much RAM do you have?

I rebooted and tried full compile again, and it was successfully compiled without error.

Seems that it was indeed something else that has been eating up my RAM. I have 16gb RAM by the way.

After the full compile I tried again to run the map in-game and the lights were fixed. (in a little low quality though) Then I tried final compile but it showed "OUT OF MEMORY" again. Well, I think maybe its my computer's problem.

By the way, I found out that maybe fast compile will break the lightmap or something. I added some entities and props and fast compile just now and the in-game lightmap broke again.

Another full compile fixed the lights though.

the failed final compile showed this message by the way:

The fast compile setting uses the preview vertex lighting you bake inside Hammer, instead of the lightmapper. There is a Fast preset for the lightmapper as well, accessible from the custom settings.

Looks like the final compile runs out when running the open image denoise filter. Those kinds of filters seem to use up a lot of memory. One thing that might help is to make sure that your pagefile in Windows is set up properly, so it can swap more memory to disk.

It should work. Maybe verify your Gamefiles ? I had an Error too and i had 12 missing Files after verify My Game Files. Maybe it helps you too . Give it a try

Thank you so much. I tried set up more pagefile and the final compile is successful now.

Problem solved.
