Painted glass render.

Hey!
I was wondering if anyone has find a good tutorial or could advice me on generating lights from a “painted glass” window…

I try different methods for Translucency, but I think I was looking at the wrong side… I try Cycles with Caustics and glass material, and looks fine… just… not really transparent and with Ray… It looked closer to what I wanted, but still or is too sharp or just noisy… Is like… if I reduce the ammount of gloss… It just seems to overlap samples of noise over the model :frowning:

I’m kind of a complete noob… Started blender a few weeks ago… Hope to not bother anyone…
Have a pleasant day readers!
