Hi, I’m gettin a headache to solve this problem should be simple.  Created a particle system “emit from layer” and with the option of sampling the color from the layer. Where the layer is alpha I can’t see no particles. But as soon as I connect an auxiliary system and I tell to sample the color from the “souce” all the “alpha”main particles emit secondary particle that are solid black. Any chance to solve this issue would be really appreciated. Thanks
