Question

unreal engine

Colleagues, good afternoon.
Please help me implement a 3d configurator like this:

I'm more interested in the mechanics and implementation using blueprint, perhaps somewhere there is a manual or documentation on a similar mechanism.
I've been scratching my head for a week now, but I can't even get close.

I didn’t write for UE, but I work in game development. My opinion: the general architecture of 3 main points:
1) make a model (cars in your example) from many components (models, materials attached to them, shaders) so that each can be replaced / painted separately
2) make a script where you set the connection: in a simple case - you statically build a link between shader properties like color - and a parameter in the script, you can also link to a mesh / game object to replace the mesh, this is how it is done in unity approximately
3) UI which you change properties using an intermediate script
