Transparency on viewport renderer

[arnaud]

Hi there again,

I experienced something quite a bit frustrating..
I have an object, I animate its opacity via the redshift shader node.
On the viewport it shows its animation properly, but when I do a viewport renderer (copy effects from viewport clicked) it doesn't animate it the way it should (in fact there is no animation at all), it just show the actual opacity from the current frame.

This doesn't make any sense to me and I have no clue how to get the same result as I have on my viewport.

Anybody experienced that?
