I’ve been playing with POPs and having fun, and I came across something that would be nice to have in the TOP to POP.
When converting a TOP with a transparent background, right now you get a full frame of converted particles with all of the alpha=0 pixels being converted to black particles.
It would be great to be able to have a Color+Active input option that allows you to use the alpha channel as an active flag. So anything that’s transparent in the TOP just doesn’t get activated in the POP. Similarly, having an Attribue Scope option for Active in addition to the existing P and Color options would allow you to use a black and white mask input as the active mask for particles.
I guess there might be some rounding issues as alpha is a range and active is a boolean, but it could be a value > 0 = on type situation.
