Hey all, nother question form a former cs1 mapper, moving to cs:s.

When compiling maps for cs1, there was a radiosity command that double the lightmap detail. It made the compile take a really long time, but the shadows loooked far better.

Is there a way to do this in hl2, and, far more importantly:

Will there be a performance hit in game?

There are no lightmaps in HL1

you can set the value of the lightmap on a per face basis now. the texture dialogue box has a field that you can enter a non-default value.

the advice that valve/others have given is to reduce the lightmap on large surfaces that have little detail, or surfaces that a player will never be close to.

everything relates to performance, so it'll be down to you to try and strike a decent balance. good luck.

There were, other wise we wouldnt have light in HL1 =P, they were just very large (like 256x256 I believe).
But you can look at a what light map size on a brush is by going to the 3d window and change it to "light maps" (right click in upper left hand corner). Other wise do what Fishy said.

Good advice. Serves another purpose as well: it keeps filesize down a bit. With the large maps of today that may be a thing to consider.
