Setting up Diffuse, Illumination, Bump and Specular mapping I'm stuck importing this .3DS model and thought of asking for some help.

If there is a model A imported, but textures must be mapped manually. On the object C of model A, there is material C, and all the textures related to C are named C-blah blah blah.

But here is the thing, there are C-Diffuse, C-Illumination, C-Specular.
How do I apply all of them onto the object C?

I wish I could've explain it in detail, but my PC isn't feeling that good...

Thanks in advance.

+Edit:

This is the model I am working with. It comes with multiple textures for a single part. How do I have it all go into one things?
I'm afraid you are going to need to take a few steps back and understand how textures work before you can get that working without lots of step by step instructions. There is a pretty good tutorial here that should help: Blender Guru Principled Shader
