Turning Pickup-able items to static/non-pickup items

[The chaser]

Hello!

I would like to ask if there is a way to turn a pickup-able object such as the lantern or the bucket into a static, purely decorative object the player cannot interact with.

Thank you very much!

Yes, it's possible. Follow these steps:

Make a new folder with the desired static item.
Copy everything to the new folder except the .ent file.
Now, in the model editor, import the .dae and, in User defined variables, make it Static.

This should work.
