How far are we going to be able to push that RT ?

I will never define myself as an artist so I did scratch my head quite a bit before deciding where to post this.
I’d most definitely consider myself as an explorer in Blender though ; so here are my first attempts at transluency, RT transparence and using layered textures to control RT mirror.

All procedural textures and modeling. No halos or flares.

I’d post the .blend but it is a bit heavy at 1.25Mo zipped.
I can mail it on request : put “alien papa Noel” somewhere in the title of your mail.
