opacity on object

hello,

i want to make my object with transparency for glasse, for exemple.
i want a reflective environnement box, and opacity at 50%.

i only fund opacity cutout and it didn’t work as i want.

ok,

forget this , i finally fund that is depending from PSD file.

A quick solution, if you want a uniform alpha, is to set the alpha in the main colour. The texture alpha is multiplied by the main colour alpha to produce the output alpha. Even with a solid texture, a 50% main colour will make your object half-transparent.
