Changing texture of an amnesia object

[nemesis567]

If you mean Real-Time texture changing. That's not possible. You can although retexture the object, which is an easy task to do. You just open the dds file for the diffuse material of the box and in photoshop you replace the faces with a present's faces. IT's pretty straightforward as long as you now how to use PS or GIMP. I think a plugin is needed for PS to import/export dds files.
