Particles wont work with sobel post process

if i apply sobel material to post process particle effects wont show…anyone know how to fix this…thanks

This is because translucent materials do not render any depth and the sobel effect relies on scene depth. If you want them to automatically work with the effect, they will need to be masked so they render a depth. Otherwise, you will have to manually do your outline inside of your FX materials.

thanks for the answer ryan
