Only Source texture work on my Model, Help.

I’ve created my model with Hammer Editor with Propper.
The model work but since hammer and game reboot, the model show only source texture but no custom textures.
In the props menu, we can see the vgui show all of the model but when i spawn it, appear only source textures.
