SunSpreadAngle must be capitalized
It turns out, this keyvalue, SunSpreadAngle, must always be properly capitalized for it to be read by VRAD. By having it lowercase in the FGD, the final result will be a lowercased keyvalue in the entity lump, which VRAD skips over.

The variable is read from here: https://github.com/ValveSoftware/source-sdk-2013/blob/0d8dceea4310fde5706b3ce1c70609d72a38efdf/mp/src/utils/vrad/lightmap.cpp#L1483C1-L1483C64
The case-sensitive strcmp that checks it is here:

That's quite dumb. I think I'll also add a postcompiler transform to adjust the casing as well then, to fix this issue.
Related, does HA always emit (or intake when importing) lowercase keyvalue names?
Nah, srctools does lookups case-insensitively, but preserves the casing used when it’s initially set/parsed. I need to revamp this though, currently it’s directly exposed as the keys dict meaning it has to just loop over all the keys each time…
Ah okay, thanks! Was wondering as I was futzing around with it the other day
