Uploaded a new version of TyrQuake (v0.53) which fixes the particle depth buffer bug in glquake (used to make the particles look like triangles when rendered in front of water textures). The fix was taken from Fitzquake (thanks Metlslime), which has had this fixed for ages. I thought it was a lot more complicated than that, so I had been avoiding doing it. Also for those building from the source package, the build system has had a fairly major overhaul. Now it's got proper auto-generation of header dependencies, which makes it a bit nicer to deal with from a coding point of view.
Update: Note that you'll need to make sure you set
gl_texsort 1 for the particles to look right. I'll
have to make sure that's the default next time (and probably remove
the option altogether).
