Hello. Im new to this forum. Ive been toying with the new material sliders in 2.32 and I cant figure out how to do refraction. Somebody PLEASE tell me how to use the refraction sliders. thanx in advance
press the ray button in the display buttons (next one pan, shadows, env map…)
press the raytransp button for your material
move the fresel slider up (all the way is a a start)
set IOR to 1.5 or so
render
Very cool! Thanx. Ive been trying all the “fakn refractions” tut’s for almost 1 and a half years. Now im officially satisfied… 
im almost done with an animated tut on raytracing which includes some basic refraction. just wait
