Hi!
Recently Source SDK 2007 has been updated, with a painful side-effect:
Black mesa and the others source 2007 mods no longer work.
I tried to run Black mesa and Nmrih and I had this:
Unfortunately, It seems that this new update is creating problems also to those that use hammer(and develops source 2007 mods).
If you’re playing BM right now or if you’re developing mods(Hey Hezus, Text, DKY…do you hear me?) for BM you should prevent steam from update the Source SDK base 2007.
There’s a thread in nmrih forums about this issue
Steam Dev Forum Thread about this issue
Zombie panic source forum thread
note for moderators: I had to create this thread in this forum because of the importance of this issue.
