My previous release was not a pk3.
What you see in your screenshots, are the missing model for shell casing.
DarkPlaces creates these dummy models in order to avoid crashing.
So you MUST use dpmod somehow.
Maybe you use a shortcut "darkplaces.exe -game dpmod" ?
If so, dont do it. Start darkplaces.exe without anything.
Put my new pk3 in your Quake\ID1 folder.
I will doublecheck it, when I come home this evening
and come back to you if I find something.
