Smart Object Mask

[Afterimage]

I cannot get a SO mask to respond to the Brush tool. Can you not mask  a SO filter?

Yes, you can mask a smart object filter, can you post a screenshot?

Not »send«, »post«:

Please check this out 

https://www.take-a-screenshot.org

and then post a meaningful screenshot with the pertinent Panels (Toolbar, Layers, Channels, Options Bar, …) visible.

Could you please post a screenshot with the pertinent Panels (Toolbar, Layers, Channels, Options Bar, …) visible?

I know this is going to sound obvious, but is the mask targeted? Painting with black? How about specific blend modes on the Brush Tool's options bar? Is it set to Normal?

A Smart Object Layer cans have only one Smart Filter mask which can not be linked to he layers content. All Smart Filters on a smart object layer  are  mask by the single filter mask and the filters are applied in the order that were attached when the need to be reapplied.

Be careful moving the object posution  The filter mask can not be linked.

So why does the SO mask even show up?

If it did not show up you could not mask a smart filter.  There is no add or create Filter mask menu item. If you want to filter part object and had an active selection of the area that selection hast to be recorded into the filter mask. Smart object  pixels can not be changes. If other changes are made to the smart object layer the smart filters may need to be reapplied the selection needs to be available.  If a change  like a transform is made not only do the filters need to be re-applied.  The filter mask may need to be worked on for the filter mask can not be linked with the layer's content The filter mask would not be transform like the layer.
