i got the model working now I'm just having trouble getting the ui icon to show up even after changing the lines in both the items_3d.xtbl and items_inventory.xtbl files i'm just not sure why
For the icon, you need to edit bitmap.xtbls (depending on which language you're using)
Need to find "ui_hud_inv_w_ar50grenade" and under that, you add this:
<Properties>
<Name>ui_hud_inv_w_ar50</Name>
<StartX>922</StartX>
<StartY>250</StartY>
<ImageWidth>88</ImageWidth>
<ImageHeight>48</ImageHeight>
<PersistFilename>D:\projects\sr2art\Interface\bms\hud\ui_hud_inv_w_ar50.tga</PersistFilename>
</Properties>
But.. if you want to replace Ar50 firework's icon, just search "ui_hud_inv_w_ar50firework"
To make sure, this is how it should look like on each files..
