All our 3D models were created in MAYA based on official factory blueprints(exterior),interior is done basically it isn't like original one .They are created maximally accurately and close to the original proportions.
The models are provided with all main parts separated(photo).Models contain all materials needed and they are easy to modificate or removed. If you had any difficulties with the model we are more than happy to help you.
Renders are made in Maya 2019 using vray 4.3(studio environment is not included in the set). If you need any other formats feel free to ask for them,we are more than happy to provide them for you.
