Face extraction render pass Eyes and Mouth not visible

Hi creators !
I follow a very nice tutorial How to create a smoke effect with render passes in Spark AR Studio | Smoke_tutorial about smoke effect from this lab thanks to https://www.instagram.com/iamcraiglewis2/ who send me the link and I manage to mix dissolve and dust effect but I’m stuck to display eyes and mouth or entire body in addition to the dust/smoke effect…
I manage to display them but dust/smoke effect don’t show up :sweat_smile:
Do you know what I’m missing?

Thanks for your help !

The magicians behind the Smoke tutorial @Boris @josh_beckwith might have a clue :smiley:


Hope so :blush:
Thanks Sarah!

Hey @jackyvignon! I wonder if it’s because of the black background? It looks like your delay frame has a black background, and there’s a blend to black after smoke dispersion. Once you can make the smoke effect transparent, you can add another blend right before “device output” to add the camera texture.

It’s always hard to know for sure just by looking, but I hope this helps!
