custom items

is there a way to add custom items. we have the plug nades plus and they use the g1 gernade but they will not follow the stack sizes. 

Nade Plus - Plugins - Codefling

they are a skinned gernade. 

Hello!

Unfortunately, the Stacks plugin cannot handle individual item skins - it only works with item types. The G1 grenade from Nades Plus is just a skinned F1 grenade, so it will follow the same stack size as regular grenades.

Solution: Use the console command:

stacks.manage stack set grenade.f1 [stack_size]

This will affect ALL F1 grenades including your G1 grenades.

The plugin currently doesn't support different stack sizes for different skins of the same item type.
