I bought your videos, simply fantastic. I have been working with UE4 for the last 3 months with no prior UE3 knowledge (or any other engine for that matter). It took me this long to finally start understanding PBR. The most confusing factor was the specular, in older engine it worked much differently. I know that much. Now I can see it’s just a value for the highlight brightness in the roughness.
If you come out with more tutorials at a reasonable price, I will continue to pay for them
