To allow downloads, before connecting, either
- open console (shortcut Shift-Esc) and type \seta cl_allowdownload 1
- or, set via menu Settings -> Game Options -> Auto download: yes
It will download the necessary SG1.1 files into your SG user directory. After that, you probably will be able to connect to any SG1.1 server.
Troubleshooting:
- If you don't see the right textures, \cl_allowdownload 1 and \reconnect
- If you don't hear the right sounds but some repetitive chopping sound, \cl_allowdownload 1 and \reconnect
- If SG warns about "Invalid .PK3 referenced", \cl_allowdownload 1 and \reconnect
In case of SG1.1RC1, there might occur the problem of a repeated download of the file baseq3/pak0.pk3. In such a case, follow these instructions.
