Mapping Textures Missing

This might be noobish or whatever, but I don’t care.

I have just recently noticed all of these nice textures included in gm_squares and gm_excess_construct/waters.

I just need to know where they got the textures for gm_squares’ grass and
the texture for gm_excess_construct/waters’ water.

I just wanted to know where I could get these because these would make my map look better.

They’re most likely custom. Ask the creators.

The water on squares is default construct texture.

Ask the makers. I’m pretty sure most of the textures are HL2/episode 1/episode 2.
