I've also been using the render export buffer function.
I recently noticed the alpha wasn't working
when using the "render buffer export" feature in image processesing.
i set it to source - shadow
destination - rendered alpha.
seems to work on shading mode. cleary not for shadow.
anyone know why?
anyone know if there is a work around?
or if this is just some screwy bug.
the goal was simply to grab the shadow for a front projection.
