Hi @carlo macchiavello,
Thank you for making this report. This is a known limitation of the Timewarp effect rather than a bug. We will be updating the documentation to reflect this limitation.

A workaround would be to pre-compose the layer with Timewarp applied and apply the mask to the resulting pre-comp instead. You could also add the Timewarp's properties as Essential Properties of the pre-comp so that the settings are available in the context of the containing composition.

Cheers,

Hi @JohnColombo 
thanks for answer, i just do it with a precomp, but ... it's a annoing thing that everything in AE i should precomp to fix something, when i started to use it in 96 could be ok, but today...
ps. i hope someone update ae to solve this limitation, could be three different solution :

- add in TW a small cache where it save Alpha before fx, and restore same alpha after fx effect
- create a new plugin that cache alpha and enable to apply again in a second instance after xxx plugin (like warp stabilizer when do reverse stabilize), that avoid you to update all plugins
- finally give us ability to chance render order from mask/fx/transform/level style like in every other software in nodal or not nodal way.
kind regards
Carlo
