Preview and masks in advanced output

[pette]

Hi,
If I use some masks in the advanced output in the preview of the interface I don't see the mask, but the clip without mask... there is a solution I don't know?
thanks

These are slice masks, which are separate from your composition.
You could try to use a Slice transform on your composition.

HI,
so it is possible even with mask slices?
thanks

if I use slice the preview has the effect by superior layer, so the mask doesn't work as I want

How do you want it to work?

Hi,
the output is ok, no problem, so I try to have also the preview like the output. in the output there aren't the black lines overlay.
Thanks

Are your input slices overlapping?

[pette]

Hi,
Every slice have his level.
The layer with lines and mask are over all the others

Is really hard to undestand what's wrong there.
Are you using Slice Transform on your clip, your comp, wich slice and mask working on it?

I think you're trying to use the Advanced Output to mix stacked layers. In that case, try to make all your layer mixes and masking at composition level.
Set a Slice Transform on your clip/layer with the mask/slice you need, and turn it off from advanced out.

Hi francoe,
maybe I will try to attach my composition and advanced output files.
thanks

hmm, looks like the inverted masks on a slice transform don't handle alpha properly.
If you set the Lines layer to 50% Add blend does it look about right?
