Existence has a seizure when this shotgun ejects shells...

[Coquebern]

Howdy ladies and gents,

I'm new to GZDoom modding, so I thought I'd start with something simple like a shotgun for a DNF something or other I'd like to make for Doom. It's been modelled, animated and implemented and somewhat full functioning (With a lot of help from Wildweasel's gunlab tutorials, the Zdoom wiki, poking through Agent_Ash's 'Beautiful Doom' structure and up until now, lurking in these forums).

Does as the subject line says, but I cannot figure out why...

Here's a download for the more learned of GZDoom modding.

BIG thanks to Wildweasel for his tutorials.

*EDIT: GOT IT SUSSED! - this happens when GZDoom can't find the texture for the custom projectile model. - in this case 'wshotgun_shell.png' was incorrectly named 'wshotgun_casing.png'
