Blender 2.8 and Caustics, YafaRay? POV?

I didn’t use this add-on. I don’t know.

I can suggest my Shader add-on: Vshade.

But firstly you can watch tutorials and if you think it is hard or you are not want to deal, then you will look add-ons. Firstly you must decide what you want, and which solution to serve your want.
