	You should be able to install the package into UE4 and from there you go to Skeletons and export SK_Truck_Box. You can probably get even better results using SM_Truck_Box, but I did the SK_ version.		You should be able to install the package into UE4 and from there you go to Skeletons and export SK_Truck_Box.

		+	The next step will be to add the character to the vehicle, that is he should be able to interact with the Truck - adding event overlap to the front/back doors, and some animations to climb/enter/exit in the correct ways - perhaps he can even interact with goods in the box, or an existing driver?
		+
		+	I will get back on that...

		+	Please note that because the left window was attached '''under''' the left door, it will rotate with the door. If you try to rotate both (as when you connect the last SetRelativeRotation it will swing oddly/double... this is a standard door open BP, you can use it in many places - given that the pivot is correct! In this case the left front door opens when you hold E-key and it colse again when you let go of the E-key.
		+
		+	You can also make variations over this, say I made the window go down, when using the V-key. I had to adjust the Y transform - as the window will not fit into the door the "animation" looks odd when seen from inside. Also a made the double back-door open/close with B-key, in this case there is a bool to check what you want to do and you can naturally do the same for the window/door.

		+
		+	When this has been done you can drive the Truck directly, as instructed for all the vehicles. Wheels should be turning and you can animate. Now for your modifications of the BP_BoxTruck blueprint, for each mesh you need a separate Skeletal mesh component (like when you make modular characters). In this case it looks like this:

		+
		+
		+	Please note two thing! The window is placed under the front door. I found that that will work nicely and you do not need to worry about the transform/rotation. This will require that you saved both the door and the window correctly, with the correct pivot-point, as described above! The pivot must be correct for the rotation, but you can adjust the transformation as needed (in UE4).
		+
		+	I have set up a few interaction Inputs, note that you can use the same key board key for different interactions. The space key is here used for Vehicle Handbreak, but for jump when in ThirdPerson!

		+	You will, at some point discover that not every thing works fine. You will, by now, know how to make the materials from textures - but you can also re-use those that comes with the package. Somehow the textures will fit correctly to all of your imported assets... I really don't fully understand textures and UV, but it works!

		+	There is a reason for this, and two solutions:

		+	* Under the wrench Icon you see a modifier, this was imported from UE4.... and you can either delete this modifier, before saving all the FBX files - or
		+	* Don't use ''Preserve smoothing groups'', when you import!
		+
		+	I do not know if you will need the modifier at some point, so perhaps you should save everything in a separate .blend file?

 ==Failed experiment, with morph targets==
 The end result should be that you can open/close windows and doors. My first attempt was using morph-targets. Like whit the Makehuman characters this require that you do two truck collections and select/shif t-selec the two meshes and "join as shapes" - the selection process is much the same, but the results was very poor, as the doors do not animate to scale, they actually '''morph''', not very surprisingly!
