Extracting Unity 3D model from Kia Mixed Reality Experience (NERDS ONLY!)

This one is for the nerds and the brave.   If you have followed my previous blog post and had a tinker with the PV5 Mixed Reality app, and know how to drive modelling software, it's possible to extract the full Kia PV5 model from the app, this could be useful for measuring and creating adaptions.

I'm going to keep the instructions here brief and to the point, and they assume some tech knowhow, but then someone wanting to tinker with automotive Unity model and it's data will likely have that automotive knowhow.

Pull the PV5 CAD Model From Android Device

This will be the the type of vehicle last viewed in the app.

  • Use Android.  This can't be done on iOS, there are ways, but it's more complicated, and I don't have any iOS devices, and don't want any either. :-)
  • In your Android Device, Enable USB Debugging, it's in Developer settings, so you might need to enable that first also (Google is your friend here)
  • Connect your phone to a PC
  • Install ADB Explorer from the Microsoft store: https://apps.microsoft.com/detail/9ppgn2wm50qb
  • Open ADB Explorer, authorize your Android device (on your phone),
  • Connect and select your device
  • Select Internal Storage







  • Select the following path: Android/data/com.kia.ProductMRExperience/files/UnityCache/Shared
  • Select the next 2 subfolders (I suspect this may be named differently, depending on the model you have selected, for me it was 42cf30d001437950e39ddd01cf053bdb/e973f81e3b74fa24f8c3d58c08d5df9d
  • In this folder there will be a file, approximately 140MB in size called __data
  • Right click and select Pull and select a folder on your PC.








That's it, you have obtained the Unity 3D model it needs some manipulation to be useful, you can now disconnect your device and remove the app,  Don't forget to also disable USB debugging on your device.

Unity Model Manipulation

Next we are going to use a tool called AssetRipper to decode the Unity model.

  • Download the tool from here: https://github.com/AssetRipper/AssetRipper/releases
  • Extract and run it up, it will open up a web interface:







  • Select File, Open File and open the__Data file you extracted from your device
  • Selected Export, Export All Files and select a new folder to export the files to.
  • Select Export All Files

Opening in Unity

  • Open Unity Hub and import your model folder
  • You will likely get a warning about not having the correct unity version, let it download the correct version.
  • Once the model opens, you will find lots of pink rendering errors.  To fix these, select all the models and change the render from "Hidden/InternalErrorShader" to "Standard"  once you have done them all, you should have something like this:

Camping with the PV5

Image
The main reason I went for the PV5 was the room inside, it was one of only two EVs on the UK market that had sufficient safe driving headroom for a tall driver. I looked at getting a short term camper in the past, but the market was quite messed up, the VW Transporters sold for a lot of money even with massive mileages on them, as a primary vehicle, there was no way I was spending over £20k for something that's already done over 100,000 miles, regardless of how well someone claims to have looked after it, so I put the idea of the camper away and moved on. With the PV5 Passenger, this is now absolutely back on the table, as whilst it wasn't the primary reason for my PV5 purchase, it costs so little to adapt, and no permanent modifications, it's a no-brainer not to.  I'm going to detail what I have done, and the costs (as of Summer 2026). The Game Changer Before I do so, there is a total game changer that is rarely spoken about with EV camper.  It's the air conditioni...

Immense Boot Space

Image
One of the great design features of the PV5, something I don't seem to recall a single YouTube "reviewer" mention, is how well designed the boot space is. I don't just mean the size of it, which is already huge, I mean the adaptability of it. We are off to a music festival next week, taking the PV5, with the bed platform , and wanted to maximise the space under the bed platform.   What's great about the PV5, and something Kia clearly spent some time working on, is how easy it is to pull the boot floor storage bins out to give you even more volume. The lids slide off, the bins lift out, as do the plastic seperator bars, giving you lots of extra room below. It's a couple of minutes to reconfigure, no tools needed. Here are some pics, including the install of the coombe valley campers bed platform. The Start Slide off the tops Lift out the bins Lift out the divider bars Thats it for the boot floor, the next pics are...

PV5 Production Line (Video)

Image
Find this pretty amazing. So much automation is in play at the PBV factory in Korea.  The PV5 is designed to be built build robots, and the factory of robots is designed to handle all the different configurations of PV5 (and PV7), including many configurations not seen in Europe. The video is in Korean, click the settings cog and you can get it in English.  Enjoy!
