Porting BMS textures to another mod?

Hi everyone.

Just a simple question: is it legal to port Black Mesa textures (and models’ textures) to a Goldsource engine mod?

Thank you in advance. ^^

Bump.

No one? Really?

Yes, really.
Assets in the mod (2012) version are released under a CC license, so you can provided you credit the team. Still iffy on the Steam version.

Founded in 2004, Leakfree.org became one of the first online communities dedicated to Valve’s Source engine development. It is more famously known for the formation of Black Mesa: Source under the 'Leakfree Modification Team' handle in September 2004.
