Building Robo Recall Mods with Blueprint
summary
Uses Unreal's Robo Recall mod tool and Blueprint to make a working TwinBlast pistol mod: starts with a data-only mod (ammo capacity set to 57), imports the FBX mesh and materials, fixes physics capsules, copies a dissolve shader into a material instance, and creates a create Dynamic Material Instance to drive an emissive "gun heat" scalar (heat per shot 0.025). Adds two muzzle scene components, overrides notify_fired/notify_stop_firing to alternate top/bottom barrels, uses a 0.25s recoil Timeline and an Animation Blueprint to move slide1/2/3 and trigger — everything runs in-game.
