First, unpack the contents of the archive.

Then open the model.cfg of your bus.

At the end insert the following:

[mesh]
Bato\Kaffeebecher.o3d

[mouseevent]
Kaffee

And safe!

Now go to the sound.cfg of your bus.

At the end insert the following:

[sound]
schluerfen.wav
1

[3d]
-1.13623
5.46447
1.14539
1

[trigger]
Kaffee

And safe!

At the end, go in the .bus of your bus.

Under [varnamelist] increase the number by 1. (For example: 24 -> 25)

Under "script\rampe_varlist.txt" you add "script\Kaffee_varlist.txt".

Under [stringvarnamelist] increase the number by 1. (For example: 6 -> 7)

Under "script\TFT_Monitor_stringlist.txt" you add "script\Kaffee_stringvarlist.txt".

ATTENTION!
If you are working on an articulated bus, these steps in the .bus must also be carried out in the trailer!

Under [script] increase the number by 1. (For example: 26 -> 27)

Under "script\rampe.osc" you add "script\Kaffee.osc".

Have fun! ;)
