Altering max stack size

[Ded1]

Is it possible?  I would like to change it so metal stacks up to 1000, and silver the same ammount.  However i have no clue as to how to go about making this happen.

<stackLimit>any Integer</stackLimit>

Stack sizes can be modified in Mods\Core\Defs\ThingDefs\Items_Resources.xml file in tag <stackLimit>. Some resources doesn't have this tag (for example metal) so you'll need to add it to them.

ok thanks.  I didnt know if stacksizes were hardcoded or anything.
