Transparent sprays doesn't work.

Recently I found out how to make transparent sprays with VTFEdit and successfully created several sprays with transparent background, both me and other players can see it, but as I go on and make some new ones suddenly they all don’t work anymore, including the ones that worked, neither me nor other players can see it. Some say new sprays after the update won’t work but these were all imported after the update so I haven no idea what exactly went wrong.

Its the server settings that prevent any new sprays to be used. Nothing to do with image files themselves.

But they don’t work in single player sandbox neither

Define “don’t work”.

They must be less than 256KB.

Sprays have never worked in single player to my knowledge.

Yeah, they do only in multiplayer. So starting a 2 player game will work.
