Is possible to make recursive Render target?

Can a render target be added to itself plus another texture generated from a material at run time?
I want to generate an alpha from an array so with a “for each loop” an alpha will be created then added to the render target, once the loop is finished, set this render target as the alpha to use in the widget.

If possible how should i approach it?

Found my answer by myself, thanks to me im awesome.

What did you do?

yeah that didn’t help us other much :slight_smile:
