[FREE] Materials & Textures - Making on my Own

I will look into the physical side too, will be more interesting. It´s pretty easy to start with the textures. Making the material at some point is a little of work, cuz each have it´s own roughnes etc. + you mentioned physicals.
I will manage somehow, have a lot of expierence from CAD (the physics) need just some time to go through the manuals.
