Quote from FroyokYeah, not very fun. I must close hammer before (or after) launching the game because my viewport become black. Only a restart of hammer work to get my viewport back.
Before you launch the game to test your map, minimize hammer. I had the same problems with the regular source SDK and that's the only thing that's worked aside from restarting the editor.
QuoteIf you launch the game first, and then launch Hammer, that won't happen, and you will also have access to steam community (-hijack disables steam community it seems)
I'll have to try that as well, thanks Happy!
