Can't scale sprite

Garry's Mod mapping
#1

Hello guys ! I am working on my map with has many lights so I need to use many env_sprites. Further in work I noticed that sprites aren’t scaled, even in hammer they look bigger, in-game they are on ‘basic’ size.
I am using Source Engine 09/HL2: Ep2

I appreciate any help with that strange thing happening to it.

Are you using the “Scale” property? It works for me.

Huh ? Luckard. It doesn’t work properly for me, from that what I know basic value is 0.25, I set it to 1 and it won’t scale. I even tried to change from .vmt to .spr in place where name of sprite is.
