2D to 3D Projection mapping Tutorial for Adobe After Effects

2D to 3D Projection mapping Tutorial for Adobe After Effects


Hey Guys, Flat Pack FX here and in
this tutorial I’m going to show you how to take your 2d images and make this 3d
parallax effect so stick around you’re watching Flat Pack FX. Hey guys
welcome back to the tutorial now in this tutorial I’m going to show you how to
make this effect called 3d projection mapping now simply put this effect
allows you to take a 2d image and make it appear to be three-dimensional now
this is an intermediate-to-advanced effect so if you’re new to After Effects
I really recommend that you watch through this video a few times and just
carefully follow the steps to make sure you don’t miss anything
now also in this example you can obviously use your own images but I’ve
supplied two images here that I got from online and I’ve put links in the
description below if you want to use those same images now just two very
quick things when you’re choosing your images this effect works best when we’re
looking at some sort of tunnel street or alley way now it doesn’t mean this
effect won’t work for other images it’s just that you will get the best results
if you have an image that is of some sort of tunnel alright so the first
thing we want to do is create a new composition it’s gonna call my effect
I’m gonna make sure this is set to 1080 25 square pixels and roughly about 30
seconds in length now the first thing I want to do is just drag my image
straight into this composition and I’ll need to resize it so it fits my
composition now there’s four parts to our projector there’s the camera which
is our eyes there’s the light source which is going to be our torch there’s
our image which could be our hand and then we have our surface that we’re
projecting onto which is our wall now we need to create each one of those so the
next part is we’re going to create the camera so I’m just gonna right click and
create a new camera I want to set this to be 28 millimeters and then hit OK and
then I also want to create the first layer so we’ve got four distinctive
layers here that we’re going to project our image onto we’ve got the ground
plane we’ve got the ceiling and then we’ve got these two side planes so we
need to recreate the inside of After Effects so the first
thing is I’m going to right-click and create a solid just gonna set this as
default a white layer and then hit OK then I’m gonna come up to effect down to
generate and I want to add this grid effect and that’s just going to make it
a bit easier to see what we’re doing here now the first part of this is I
need to make it a 3d layer now we need to rotate this layer so that matches our
ground plane as best we can so we do this by going to the rotation tool and I
rotate this layer like this then I can move this into position and I can
continue to adjust this layer and scale it as well so that it fits our ground
plane as close as we can possibly get it so something like that now next I need
to adjust the material options of this layer so I can navigate down to the
material options and I need to make sure the car shadows is set to OFF the light
transmission is zero except shadows is on and except lights is off so this is
really important that these are set to these specifications now once I’ve got
that all I need to do is take that layer I can duplicate it I’m just gonna simply
use my Z property just to move it up towards the ceiling so it lines up
nicely with our edge here so something like that next I can take one of those
layers again I can duplicate them and this time I’m going to use my rotation
tool on the y-axis to move them up into a vertical position and then I can
adjust them using my z-axis here so that they line up with the edges here and
then I can reposition this by scaling it and then shifting it around until
basically these edges all line up so you can see what we’re doing here we’re
basically creating a square so I can do some very slight adjustments here and
then I want to take that layer again and I duplicate it and all I need to do is
just move it over using the z-axis and just do the same thing again I just
reposition it here until it roughly lines up with my edges here that doesn’t
have to be perfect but as long as these sort of gaps here are all sort of closed
that’s all we need you can see it’s already created that illusion of being a
tunnel we’ve created almost a three-dimensional tunnel inside of After
Effects now the last part is I’m just gonna create an end plane so I’m going
to duplicate this one last time I’m gonna rotate this layer so that it’s
flat I’m just gonna simply move this one into the distance and then just
reposition it because best I can there now it’s worth at this stage just taking
the time to get it as accurate as you possibly can but you can adjust this
later so don’t worry too much if it doesn’t all line up at this point now
the other thing we can do here is just to check how this box is all lining up
if I go to my camera tool I can actually just rotate this box around now I can
actually just move this out and you’ll start to see that we can see this box in
a three-dimensional space so you can see that my end layer is not lined up the
rest of my planes I can just simply drag this one back here and grab this layer
and move it closer to my grid and then I can just reposition this here I’m also
just gonna rotate this one slightly back into place I understand this may be
quite difficult for some of you if you haven’t worked with any sort of 3d
program or you have trouble imagining a three-dimensional space but it can be
done it’s just a matter of slowly working through it and moving each layer
a small bit at a time until you end up with everything in the in the correct
position now I can see here that this layer will need to come closer just to
help close that gap once you think you’ve finished your box I can just
reset my camera here and then just make any final adjustments that I need so
that we’re as close to that edge as possible now bit of overlaps okay it’s
just that we need to have all the edges sealed up now once we’ve got this in the
position that we’re happy with now we can now we’re ready to actually remove
these grids so I’m gonna select those white solids and I’m just gonna tap this
FX button to remove the actual grev so we end up with our white planes again
and then the last part of this is I’m going to create the light so I’m gonna
right click and create a new light and it’s very important that I set this to
be spot I need this to be 100% intensity and in my cone angle to be a hundred and
eighty degrees and my cone feather I need set to zero now most important I
need the color of the light source to be white and I need this to be car shadows
to be on the other thing I can adjust here is the shadow darkness to be a
hundred percent which is important and then hit okay now at the moment we can’t
actually see anything and that’s because we need to actually position all of our
elements in the right place so I’m going to go to this button here to go to the
to view horizontal and the view on on the right hand side is what our camera
sees and the view on the left is our scene played out from above so from a
bird’s eye view now we want everything to line up with our cameras position so
if I hit my camera layer and hit P on the keyboard I can actually copy this
position property here and I can paste it onto my light source and that’s moved
our lights in line with our camera and I’m also going to do the same with this
layer here after I turn on the 3d layer again so I’m gonna make it a 3d layer
and I’m going to paste position property onto that layer and that’s moved that
layer in line with our camera and actually need it to sit in front of the
camera so I’m gonna move move it out so it’s it’s away from the camera so we end
up with a gap that’s our image and that’s our camera layer there so we need
a bit of a gap there and then we need to scale our image back down so I go down
to my scale property by hitting S on the keyboard and I’m gonna scale this right
down now you will need to scale this down to probably around 1% or so and
then you can readjust the final scale so that it fills the edge of your screen
where you roughly had it before at the moment mines really blurry the reason
for this is because I have depth the field turned on to my camera layer and
come down to the camera options and I can just turn off depth of field and
then make the final adjustment here just to fill the edge of my screen now I’m
just gonna go back to my original one view so I can see what I’m doing now at
the moment looks exactly the way we had it before but we have to do one last
thing to our scene here which is adjust the material
options for our projector a layer at the moment is not transparent so when the
light hits it the light’s not actually passing through onto our background
layer so we need to make it transparent so the light can shine through this
layer and project it onto our background so we go down to the material options
for your image and we need to change the car shadows from off to only so if I
click it once it goes to on if I click it twice it goes to only and then we
need to adjust the light transmission from 0 to 100 and there you go
so image has now reappeared now again it looks exactly the same as we had before
but if I go to my camera tool and just simply pan around our scene you can see
the big difference you can see that it’s actually now turned it into a
three-dimensional scene I can actually turn all the way out here and it will
change the perspective that I’m looking so if I wanted to do a simple camera
move here I’m gonna set a keyframe for my position and point of interest I’m
going to go to my camera Z track tool and go across to roughly about 5 seconds
here and just do a simple dolly movement in and if I played through that you can
see straight away the difference that this effect has created you can see it
actually looks like the camera is traveling down the tunnel now you can
also do some other interesting things here by using the different camera tools
I can move the camera closer to the ground here and as my camera moves
towards down the tunnel I could move the camera over to this side of the wall and
then I could rotate the perspective so it looks so we’ve got a bit more of a
dynamic camera movement going on here there really shows how this effect is
working so you can see the difference that we’ve got there now you can see
we’re actually getting this line appear right on the edge here and that is where
the box doesn’t line up with this side of the box as well so what you need to
do is you just need to scale this up slightly and that’s just gonna fill that
edge again so just where the two layers aren’t
connecting so you just need to look out for those and then make your adjustments
as you go now that is one way to create this effect and it can get a little bit
complicated but the key is just slowly work away and follow those steps very
carefully and eventually you’ll get there
now here’s another composition that I prepared of a road and again I followed
the same principle that I’ve just shown you here in this previous one but in
this case I’m using two planes instead of four so I deleted the sidewalls and
then I went back to using my floor plane and my ceiling plane and it ends up
having the exact same effect now you can take the same principle and apply it to
a wide variety of different images and you can also take this effect to a very
advanced level where you can actually create your own custom planes by masking
a layer and then projecting your image over the top of that now at the moment
I’m just trying to keep things simple for you and easy to follow so there you
go guys there’s an introduction to camera and projection mapping inside of
After Effects I hope you’ve learnt something and if
you have any further questions about this effect please pop it in the comment
section below thanks very much for watching guys and I’ll catch you in the
next tutorial and remember flat pack effects is the flat pack anyone can
build

  1. Thank you so much for this! Very helpful! Any suggestions for making objects in the image appear 3D, for example the cars in my image appeared kind of flat. Thanks again!

  2. I did everything, when my screen is on 'fit' it is blurry but when I do my screen on '100%' it looks normal, what did I do wrong?

  3. its cool bro, but in the second example use just floor + the wall far in the back, this has perspective flaws. Or better, project the sky on a sphere from the inside. thats how we do it in nuke. anyways very interesting video, i had no idea after effects stepped up their game this much. very good job thank you

  4. HEY MAN, Thanks for the tutorial. one quick question: why when I enable the casts shadows on the image, it gets blurry? I shut down the depth of field on the camera, btw. Thanks!!!

  5. Awesome tutorial. My brain hurts but I will take your advice and watch it a few times until it sinks in. It's worth it because the results are really good. Thanks.

  6. when I set the material options for the last part to cast shadows only and light intensity to 100 it just makes my scene look white. help? I've tried many times only to end up with same end result.

  7. For those having trouble with the walls, ceils and floor being dark, as I did, the fix is under material options for each, to make sure under material options, that "Accepts Lights" is turned to off, keeping "Accepts Shadow set to only. "Casts Shadows" should also be off. Not sure this was mentioned in the tutorial, or if it was, I missed it. Great tutorial however. Many thanks.

  8. This is awesome! But I've been following your instructions for days and all I can get is a blurry image with the walls almost black and I don't know what I'm doing wrong. DoF option in camera is off, my light has the same parameters as yours, solids are in position… What can be wrong? 🙁

    Thanks for your tutorials!

    EDIT: Somebody has the sollution somewhere in the comments. Thanks!

  9. This can also be done using vanishing point then export as aep in photoshop, then imported in ae

  10. Still waiting for adobe to develop a bit more this part of Ae. Projections are critical for big projects.

  11. 06:40 you can do little of math
    link all slides with NULL so you will get(0.0.0) position
    than you can adjust all as perfect 3d Cube

  12. very cool! My brain stopped responding tho… Guess will rewatch this later xD. Btw is this english british accent? seems different…

  13. can you do the same for a video? because i want to make this effect with a 3d room of just smoke hence why it would be videos instead

  14. Heya, thank you for the detailed video. I wanted to ask you a question in relation to this technique. I am looking to turn parts of an old film into a virtual environment that you can experience with a VR headset. Can you give me any insight into how this might be done. Primarily my question in: can you create wireframes out of the footage and then bring it into Unity for modelling etc. Thanks again!

  15. Awesome Tutorial, thank you very much. As a beginner, this really brought me forward. I discovered that it is way easier to define the position of the 4 walls if you use the Pan Behind tool and snap the Axis System to one of the side edges before you duplicate the layer – then you can easily rotate the new layer along the side edge.

  16. What an amazing video!! you really removed a lot of that overwhelming feeling i had thinking about this process.. Thank you for taking the time to make and share this video!!!!!

  17. it doesnt work. I work on a google map view image, I paste the grid in the 3d bulding, but when I rotate arround with the camera all the layers aren't assemblate. How can I fix that ?

  18. Really handy!

    Does anyone have any tips for doing this with curved surfaces? I have a photo with a curved vaulted ceiling, meaning it distorts a lot when I track the camera in when I make a square box to project on. I can't figure out how to make a curved 3D surface, but there must be a way.

  19. Also another thing to add. If you are missing the light transmission option under "materials"….
    Make sure you have your renderer set to "Classic 3D" (not "Cinema 4d" or anything else).
    This had me on a wild goose chase for 2 hours.

  20. Great tutorial. When I activate 3d on my solid layer the generated grid is gone, making it very difficult to adjust the 3d layers. AE CC 2019
