Hi,
Even though the two vehicles have not yet landed in Unreal,
they already look great in 3dsmax. A tool like 3dsmax allows you to:
● To correct the vehicle's dimensions and to guarantee working units in centimeters -
just like in Unreal.
● To define axis systems and orientation of vehicles -
according to the guidelines of a graphic engine.
● To detach each wheel's geometry into a separate object with a private axis system.
● Allow adding and replacing objects in a modular way inside a trunk.
● And to filter geometry according to material types without splitting into separate objects.
In other words,
One object, with access to 21 materials on average.
It's the first step. And if everything is in order within 3dsmax,
then you are guaranteed a seamless integration with Unreal.
The software can also deal with lighting and photorealistic materials (PBR),
but we will leave that to the second step - with the help of Unreal.
Meanwhile, the images below show the result just before switching to Unreal.
