Particle illusion doesn't open my background layer

Hi. When I want to add a moving effect on top on an image and hit ‘Launch PI 2022.5’ it will show me the effect but not the backround image on where I want to put the effect on. What am I doing wrong?

Hi,check you have Composite over … selected,

What host (program) are you opening Particle Illusion from?

Hi there

It can be so easy. Thanks for your quick response and help.
Im using PSD 2023 as host, opening Boris Optics and from there Particle Illusion

Many thanks and kind regards

Note that in 2023.5 it automatically switches to “composite over video” when opened so this should no longer be something that trips new users up.
