Problem with Alpha property in Particle Simulator with Layer emitter
Hitfilm 3 Pro, Windows 7, i7 4770k 4Ghz, 16GB, AMD 7950 3GB, driver 15.7.1
I am trying to do an Aurora Borealis with the wiggling we see in typical timelapse video. I am using an atomic particles comp to create a line and wiggle it around with fractal movement. I then add Demult to get an alpha channel. I use this layer as an emitter in the particle simulator. The screen shot shows this with the AtomicP layer still visible.
My problem is that the Alpha particle appearance property has no effect when the layer is used as the emitter. The particle textures are always 100% opacity no matter the setting. The particle Alpha lifetime setting is OFF. Change the emitter to any other type, with no other changes, and the Alpha property works as expected. I believe Alpha should work with this layer emitter as it does with other emitters and I believe I have it setup properly.
