Spray tags in portal single player?
I've looked into getting spray tags working in single player for TS13 and I don't seem to be able to do it.
I know that:
cl_playerspraydisable 0 - enables sprays
cl_logofile - sets the file name (materials/decals/spraylogo.vtf by default)
impulse 201 - sprays the decal in multiplayer
So with all of those you would think that I'd be able to make my texture, tell portal which texture to use and then spray it on walls, but no. All that happens is I get the spray can sound and thats it, no decal appears on any wall, it doesn't say it failed or anything.
I am doing this all via the console at the moment, no point getting point_clientcommands to do it when the basic commands don't work on their own
This has really got me stumped. 
Any help?
I've noticed certain surfaces in TF2 multiplayer that even if you stare right at them and hit your spray button, all you get is the sound and no spray. I'm not sure if it's a texture issue, but maybe it is?
I've yet to notice that.
My only problem with TF2 and sprays, was importing them in the first place. Once I figured that part out, i've had no problems.
not all textures are spray able, and react how you say.
Ok, so what makes a texture sprayable/not sprayable?
Also I tried info_projectdecal and that didnt seem to do anything
