I am relatively new to using After Effects, and I am working on recreating a scene similar to that of the Upside Down from Stranger Things.
That said, there is ivy on the walls. The lighting and particle effects with Trapcode Particular is not as much of a challenge, but I am struggling with 'overlaying' the ivy image over my video background. The video background is simply a parking garage where I'm aiming to cover the concrete walls with the image.
I have not been able to find an in depth tutorial of this, mainly because I am unsure if "overlay" is the appropriate term and I am searching for the wrong tutorials.
If anyone could point me in the general direction of what I'm looking for in terms of help/tutorials/terminology, it would be greatly appreciated!
