Sorry for the late response. I should have explained the screen cap a little bit better.

The image shows one of the many pre-comps I created for the main composition. The selected layer is the solid I’ve been having trouble with. Every pre-comp I created (about 20 more or less) needs it for the glow (created with fast blurs) to show up. When I turn them off (in every pre-comp I have), I finally get the transparency I need, but in my main comp the particulars stop showing.

I hope I can explain myself better with these screen caps.

Here’s an image of the main comp:

Every pre-comp looks like this:

Each solid in the pre-comp creates the black background that blocks the alpha/transparency I need. But when I hide them, the Particulars disappear:

And when I go back to my main comp, they are also no longer visible:

When the solids are not hidden, the Particulars show but there is no transparency.

I hope it’s clearer this time.
So does anyone know a possible solution that might prevent the Particulars to disappear when I hide the solids so AE can render an alpha channel?

Baw.. yeah the thread kinda messed up and I thought I had got it right.

Anyway, I tried what you told me and, indeed, the black background has no transparency. I checked my 238423856965 layers and what i found is that there are some black Solids I used as background to add some glow with adjustment layers (using fast blur) to the Particulars. What I noticed is that, when I delete this solids, I finally get the transparency I need, but the new problem is that the Particulars don’t show up anymore over the video.

This is a screen cap:

Oh God. You’ve no idea how relieved I felt xD haha! So if my final render shows the Particulars over black background, it rendered correctly??

Thanks for your responses!

Yes, I definitely need to do some research regarding alpha and compression, it’s just I haven’t had the time yet and needed some quick advice being that this project is due tomorrow Dx

Okey, I did, hid the video and clicked “toggle transparency grid” and all i can see is the particulars over a black background /:

[Joey Foreman] “You can also see your alpha channel by clicking the RGB icon on the comp panel and choosing alpha.”
When I clicked this, everything turned white.

I don’t think there is transparency to render, right?.. but I’m not sure, how can I change this?
