How to add tint node in master material to tint albedo in specific color???
Can someone explain please?

In your material plug your albedo texture into an input on a Multiply node and then a Constant3 node into the other input of the Multiply node and then plug the output of that into your albedo slot.
Constant3 is like an RGB node so essentially you just multiply your texture by a color and that will change the color of that texture.

Why you guys need do everything to be doing only from cientists from NASA?

Honestly…

I have no idea what your saying at all.

Multiply it by a vector3. Also, read this Unreal Engine 4 Documentation | Unreal Engine Documentation
