How To Add 3D Elements in Adobe After Effects | Adobe Video

going to be working a lot in After Effects today this is kind of the final form of the thing that we're getting into swerving in and out of various uh 3D auta if we make a new composition here I'm going to bring in one of those Italian plumber blocks. glb this is a glb file but this is a real 3D object it has depth open up Adobe Illustrator here this is just a circle it's got a stroke on it and then I've gone to effect 3D in materials extrud and bevel come over into materials I've given it some roughness I've made it very metallic which is going to make it reflective just come on down to the bottom and say export 3D object and then you can send out that gltf or the USDA the other day together here's basically where we finished off the person cut out we had their board cut out we did a big big day of Roto brush here to get this chopped out for us I'm going to duplicate one of those and then I'm just going to remove the rotor brush from it and that's going to give us our Clean Plate we need to extract some data from this so we are going to 3D camera tracker effect and apply that it's placed these little track points all over they are appearing on points of contrast that are consistent throughout the image if you twirl into the advanced you're going to see the average error which is you know how erroneous this might be we generally want to number under one you want to clean it up so this person is moving around they are not a suitable candidate to get points on them so you probably want to select any points that appear on that that moving person and get rid of them I'm going to select all of the points over here that are hanging out and you can see that this uh big circle feels correct in terms of being on the ground so I'm going to right click and I'm going to say set ground plane and origin that means that 0 0 the middle center of our world is over there where that Target was at I'm going to right click I'm going to say create a null and a camera and if I put the word stuff a two-dimensional layer between the board the guy and The Clean Plate you see stuff is neatly contained behind this person but if I want stuff to live in the world I simply must make that a three-dimensional layer I'm going to call up the position of that null I'm going to copy that position and I'm going to just paste it over here it's behaving as if it is stuck to the ground and it helps because we put a null that we know was tracked to the surface so we could try to rotate it to be in line with the street we might kind of bring it down so you see this wonderful widget here this Gizmo if you hover over and you just grab say The Zed here then you can start to tilt that away we're going to switch into World access mode meaning this Gizmo is now aligned to the world that we're living in not the the object or let's switch into View mode all the axes are aligned to where we're looking make sure that you are in advanced mode here couple of Taps on the a will bring you the ability to give this an extrusion depth what do you think about this let's do some true 3D things let's just drag our gulb out here so we are going to pick somewhere for a gulb to live so I'll just right click on that let's create a null I'm going to find the position of that I'm going to find the position of Italian plumber block parent using the pick whip holding down shift point it to that here make sure we're in object mode we'll just raise it up a little bit and maybe I will shrink it down you can see we got it twirl down into the Transformer attributes and I'm just going to hold down option click on the orientation I'm going to type in wiggle I'm adding an expression here instead of using key frames I want this to wiggle say 0.5 times a second 90° and if we just kind of scrub through you can see that the block is having a tumble the board and the guy are in front of the blocks therefore they are going to appear to be in front of the blocks now if I wanted something say in front of the skateboard here then let's bring some rings out into the mix selecting the 3D camera tracker let's say we start around here so I'm going to go ahead create a null there so we got another track null in the world then we are going to take our parent that to the track null and we need to make sure that this is going to be in front of the guy we're going to move it up off the ground we're going to scale it down quite a lot this is feeling a little bit more like it's in the middle of the road stay creative be kind to each other and I'll see you all around the internet okay bye for now
