MAX_MAP_LIGHTBYTES exceeded error

[Vartazian]

MAX_MAP_LIGHTBYTES <93 MB> exceeded... more than 31 lightmaps used. What does this mean? How can i fix this error. ps: my map is unbelievably huge..but it didn't compile this last time. Is there a limit to the amount of large brushes or somthing?

I only have 1 worldspawn. and 1 light in the entire map right now..

edit: I deleted some massive brushes and it compiles now...could it possibly meant that i am reaching the max lightmap possible by the worldspawn?

Use smaller brushes to make up the larger brush.

The cutting the brushes in half didnt work, but I switched out the floors in the map for CLIP, which is invisible so I figured it might not have a lightmap associated with it. turns out i was correct.. so this is has enabled me to add at least a few more jumps worth in the map without going over the limit

As always, are you making use of structural and detail brush modes?

[Vartazian]

Im actually not sure what you mean by structural brushes. Caulk? etc?

Select a brush > Selection menu > Make Structural

All of my brushes are structural because that is the default brush in radiant apparently
