Replace A Flat Referenced From An Iwad In A Pwad

[lizard808uk]

Currently the PWAD is referencing a floor tile from the IWAD and I would like to know how to change this. Is it possible to import a new graphic to the PWAD and change the link its referring to from the IWAD to the PWAD?

This sounds confusing and it is. No amount of Google searching has helped me on this.

I've sorted this bit out now. I didnt click on include all flats in Wintex or something. My query now is, is there any way of changing sprite behaviour? Its just that having an alien shooting a pistol isnt really believable. I guess this is where those annoying .DEH and .STR files come in?? Bugger...
