1. The hr4 textures doesnt download, if the client has a lowres texture and hr4 textures are enabled.
2. The textures (hr4 and low res) doesnt download, if the server stored them in a folder with uppercase letters. Wrong path in bsp? Linux server error? Download system error?
The (windows) client ignores uppercase and lowercase letters and load textures from both of them.
On the linux server it must be lowercase (to become a download).
Its a problem with the CTP1 and CTP1/HR4 textures for example.
PS: cl_drawtexinfo shows the texture path lowercase.
