  • Make Trapcode Particular appear in front & behind 3D object

    Posted by Alejandro Chappanas on November 18, 2020 at 12:26 am

    Hello! I have looked high and low and can’t seem to find an exact answer on Creative Cow or anywhere, really..

    I am trying to make my emitter travel through Z-Space in an upwards spiral (like a Christmas tree)

    I have successfully made a light that travels in a nice motion path to do this. I have rotated the camera around the scene to confirm that the path is as I want it to appear.


    I then created a triangular object, made it 3D and placed it in the middle of the particle path.

    PROBLEM: I cannot seem to make the particles look like they are going in front of and behind this object… What am I doing wrong here?

    Project file is attached:

    AE: 17.1.0 (Build 72)

    TC Particular Suite 16 – Particular 5.0.0 (installed on 18 Nov 2020)

    Obstruction layer should do it. That is under “visibility”. If that is not behaving as you want it, I believe you will have to make 2 instances of particular. So get the particle exactly like you want it. Then duplicate that layer. Again, you will have to play with the “visibility” settings. Change the far and near vanish on those 2 layers until the end where your layer lives.

    I opened your project and also could not get it to work using Obscuration Layer. So I precomped the christmas tree, moving all attributes into new comp. Then in main comp, I make the new precomp 3D, turn off accepts lights, and then in particular I chose that layer as the obscuration layer. Seems to work now. Hope it works for you. Cheers.

    Wow man… That is it!!! Solved.

    Gotta say though, I really had no idea where to look when you were talking about the obscuration layer… You learn something new every day, huh!


    Whilst on my search for this setting, Google also revealed this amazingly simple tutorial, which is exactly what I needed, but as usual, sometimes it is incredibly difficult to find a simple and solid answer if you don’t type in the right keywords. (‘Obscuration’ is what helped!)

    Why this never came up in my searches this morning I do not know.

    Anyway; I really hope this helps people with the same question! Thanks for your speedy help, Kevin.
