Can't stream texture modification

Hi guys,

I have some trouble streaming texture modification.
For the stream configuration all is well executed, I can stream vehicule without any problems.

But I want to stream a modification on a building and this is where I have a problem.
I modded this building myself and it work on soloplayer but when I try in my server I can only stream the normal texture, not the high quality one and I wonder why.

Is anyone has an idea ?
