How to load 3d models in unity?

Question

3D

Hello.
How can I download all these files as one or I don't know. It's just that when I open the gray model in unity, it's simple. and when I open "corei7.obj" in 3D builder (program in windows'e) it asks to export other files as "corei7.mtl, core-i7_01.jpg, core-i7_02.jpg, core-i7_03.jpg" after that the model colored, etc.
How to solve this problem?

Answer 1

Create a material, add textures to it, apply the material to the model.

Answer 2

read everything from the section at the link, study, pull up the theory
Starting to work with the unit and not getting somewhere in the lesson on creating and using materials is not realistic.
It means that you almost didn't watch the tutorials on working in the unit, did you just have some scripts?
