keyword to filter out episodic textures?

Hello. When browsing textures, is there a keyword to filter out episodic content?
(I like to try to make maps playable for people without the episodes.)

You can’t exclude filters, however you can try using some of the HL2 filters… Be warned not everything has a filter so you’ll miss out on textures.

Hm, I feared so. Ok then, thanks!

What I do is generally map using my knowledge of what’s episodic and what’s not, and then when most of the texturing is done, I load the map in the HL2 engine of the SDK and hit Alt+P to check for errors. It will tell you where the missing textures are, or what they are (I haven’t done this in a while, mind you) so either way you can go in and replace them.
