i disagree, Agustin,<div><br></div><div>As I understand, a mix between glossy and glass shaders will always have reflactions as long as both are glossy. So, if I can't have a glass without reflections in Cycles, I still don't have total control over this kind of material.<div>
<br></div><div>A transparent shader with IOR and color controls would act like a "difuse glass" and would be more sueteble to mix with a glossy shader. This would be more intuiteve and efficient to mimic things like liquids, that are not "glasses", but heve do be made with glass shader today.</div>
<div><br></div><div>Glass shader seams to me as a "meta shader" and we lack a proper "basic shade"r do create transparent materials.</div><div><br></div><div>My humbble proposition is to have a transparent shader that at its default acts like today, but presents slots for roughness, color, IOR and perhaps absorpsion.</div>

and a refracted transpent shader, i would like this too, to controll the<br>
amount of gloss shader just leaving the refraction, so we can do our own<br>
gloss on it<br>
