standard DM maps/models in source mods

Hey everyone,

Im writing a mod that is essentially a modified deathmatch for HL2.

I remember with HL1 that you could create mods that would look for
their map and model files in the standard HL folders as well as in the
mod folders, effectively inheriting HLDM maps/models and then adding
their own.

Is there any way with source mods to change the paths that the mod
looks into for map and model data, to mimic this behaviour? I dont
really want to force people to copy over their whole maps and models
folders from HL2DM into my mod folders.

cheers!

bump!

anyone worked this out yet?
