@BéJleC - Sorry wasn't paying attention when posting the other comment.

The spawned ammo stack size can be edited in the types.xml file that corresponds to the ammo you're using. (vanilla ammo/vs modded)

Look for <quantmin> and <quantmax> values.
These work as percentages from 0%-100%.
If you see -1 this just allows the CE to spawn everything in random stack sizes.

Change the -1 to whatever percentage you'd like, but keep in mind the percentage you use will have to add up to a whole number as the game cannot spawn fractions of ammo.

i.e. - If your stack size is 1000, a <quantmin> value of 10% would spawn stacks of 100 rounds minimum. Hope this helps.

After installing the mod, all spawned ammo and grenades began appearing in stacks of 200 or more. :\

Thanks)

BéJleC - This mod is client side as players will need the override to use the stacking feature. Also repackable, hope this helps!

Is this mod serverside only, or does it require a client install?
