me too! it   would be a handy feature after all.  but  your  workaround  is  great!

We have this on the list. We actually had a beta of a feature, but it had a number of issues that stopped it from getting released.

The method shown using the virtual stage is the method I would personally use at the moment. It is very flexible and requires just one level of video routing.

If you're using a composite mapper as a 'mask' then - so you don't need to warp or adjust the image itself, but want to create an irregular shaped edge to it, for a non-square projection surface for instance - then my preferred technique is this:

> Create a virtual stage called something like 'mask 1'

> Connect a 'background colour' actor to a projector set to output on virtual stage 'mask 1'

> Open IzzyMap on that projector and draw your mask using composites, grids, whatever you need

> Back in your scene bring in a 'get stage image' actor and select the 'mask 1' stage. Use this image with an 'Alpha Mask' to apply the mask to your main output.

> If you need a soft edge you can apply blur to the mask between the 'get stage image' and the 'alpha mask'.

Pitty indeed,  Can  i put it under Feature Requests?
