AR Portal Setup With Universal Rendering Pipeline And AR Foundation (Unity Stencils)

In this AR Portal tutorial, you will learn how to create an augmented reality portal with the Universal Rendering Pipeline, we will be looking at rendering objects and how to apply various stencil options to mask what is visible through the portal wall.
I also want to bring Christmas by using various Christmas like decorations including 3d Christmas objects, particle snow effect, and LiDAR scanning which will be used to simulate snow.

Thank you very much Dilmer. I'm surprised that you has made so many very valuable tutorials.

[@dilmerv]

Thank you 🙏 I appreciate the feedback and many more in progress.

Thank you for this tutorial ... 👍

[@ErsinBactisa]

Hi! I made a portal project where you can enter the portal. I'm trying to make the virtual scene lower than the portal, so when you enter, you should fall down and see the portal above you. I put a rigid body on the AR Camera, i disabled collisions between the AR Session origin and the camera, but the camera still doesn't fall. Do you know why? Thank you!

[@syedhuzaifaali5322]

Great Tutorial. I have a question when I create a shader with ZWrite off it does work in the editor but not working in my android the portal window just shows nothing it should render the things behind it like in the editor but it isn't showing that. I am using built in render pipeline

[@wanglinda2212]

Thanks for the amazing tutorial! The question(AR Mesh Manager scirpt ) at the end of the tutorial bothered me.... I want to know the details of the Script and in Mesh Render is a cube(Prefab),what is the purpose of..? What if I want to walk into the InsidePortal long distance....

[@user-we6si4mi3x]

Nice Tutorial ^^

[@dilmerv]

Thank you !

[@user-we6si4mi3x]

​@@dilmerv hey hey! when I start the application, the portal is not displayed for me (this is the window through which you can see what is inside the portal), i.e. apparently the shader does not render, do not tell me what the reason can be? tell me please ^^

[@GameDevHQ]

Hey Dilmer, did you ever upload this to your github? Can't find the repository. How do you handle the masking for the camera? If your main camera walks through the portal, all elements will be hidden.

[@dilmerv]

Hey there send me an email with your GitHub username and I will grant you access, normally that repo is only available through Patreon but I know your channel so we are good to go !

[@volkerku]

Great tut, thx. I stumbled across an issue, where the insidePortal world has a white background which I don't know how to change. My main camera has a solid black color as background (I'm not developing for AR) but wehatever is oin the InsidePortal layer has a white background. Any idea?

[@davidmarywhite]

do you think it's possibile to attach a stencil portal to a AR tracking image? I tried, but it doesn't track the image with that shader

[@muhammadrezahaghiri]

Thanks for the great tutorial. I have implemented each step you mentioned, but I have a huge problem. The problem is that my portal is not working. When I change layer mask for objects, they disappear and it means everything is fine. But I don't know why my portal wall (in my case, a simple cube) isn't working.

[@TheMetalFreshTiger]

Try with a plane

[@CurlyFreak929]

Hey thanks for the tutorial! Wierd problem but any idea why I can only get the masking effect to work if I change the Forward Renderer to include the render objects. If I create a custom URP Renderer like you have done in the tutorial then nothing happens Edit: So I found out the URP pipeline asset has to be set to the Rendering field in Quality Edit > Project Settings > Quality

[@vigneshgovind9002]

you saved my life thank you so much :')

[@maxwriter5187]

mannnnnn, thank youuuuuuu

[@ajbarry99]

Hi Dilmer, thanks for the tutorial. I tried this with unity MARS, and it doesn't seem to work? I assigned the new forward renderers in player settings to the graphics, followed the instructions, but the mask doesn't mask out the InsidePoral layer. Any ideas?

[@dilmerv]

There is really nothing specific to MARS that would make this not work. Maybe look at my blog post as it has step by step just to make sure you did all steps www.learnxr.io/members/posts/47320-ar-portal-setup-with-urp-and-ar-foundation

[@grantlin7455]

I'm curios about wht I don't have the button " add Render Feature " just like the Dilmer did at 8:03 ? I can only add one option called " NewARBaclgroundRendererFeature(AR Background)" and can't cutomize the name, event, opacue...etc. If anyone knows the reason plz tell me, thanks a lot! ps : I use unity 2020.2.6 ,Universal RP 10.3.1

[@ManuelGutiRM]

Unfortunately, this isn't working on any of my projects. I've watched this tutorial multiple times and I don't think I'm missing anything. Is anyone else having issues?

[@umutduran1784]

I made it work somehow, but when I pass through the portal, everything inside the portal disappears.

[@underbelly69]

Can you update this tutorial for quest3 pass through ?

[@hilarytsai7415]

Is there a way you can apply this technique with 360 video? I was following a tutorial on 360 portal but it turned out to be outdated.

[@rendermanpro]

Hi Dilmer, quick question (while documentation is messy),if I have multiple assets in fbx, how can I import and assign materials and create prefab from it in scripted way? Tried to find and but no clear.

[@dilmerv]

First you need to import them into Unity, I would say put them in a models folder, then drag them and drop the fbx into the scene view (this will create a model Unity understands) then from the scene view just drag them into a new folder (Resources/Prefabs) once you do this you can also load them in a scripted way, also once they are Prefabs you can also assign them materials or if they had materials already you can also import them into Unity at the time you drop them in Unity.

[@dilmerv]

If this still doesn’t work for you let me know and I can make a video. Thanks

[@rendermanpro]

@@dilmerv Thanks for a prompt reply. I mean totally scriptable way? without manual steps. Like in Unreal I did it with Python, but with Unity it kind of very confusing. You have at least in one video that you had run Unity from command line to do something. In general would be interesting (for example you have 4 different socks models with different texture like in this video) 1. Scan folder for fbx 2.Recreate materials and assign to the model 3. Create prefab. Might be it is easy, buy I didn't find any (at least cleat) tutorials about that on youtube/google and it is very surprising.

[@rendermanpro]

[@Adilxec]

hey there why is the camera not rendering if i go inside the portal

[@nurhidayahhamri2100]

Hi and good day, can i ask something? before we apply this ar portal, did we need to insert first the ar camera? thank you for your time

[@nurhidayahhamri2100]

Or do I need to import any sdk related with ar portal? like ar core, ar foundation and all of that Or I just need to install it from package manager?

[@dilmerv]

Yes you will need to add AR Foundation, ARKit / ARCore plugins, and setup all the prerequisites to deploy to the mobile device. Take a look at this doc for instructions: docs.unity3d.com/Packages/com.unity.xr.arfoundation@5.1/manual/project-setup/install-arfoundation.html

[@nurhidayahhamri2100]

@@dilmerv for AR Foundation , ARkit/Arcore plugin, do I need to install it from package manager or I need to download from the outside?

[@charlesferry9465]

Thank you for reply and videos I want to something about portal I can't go in there why? If you have free time please make tutorial I new in this industry 🥺

[@dilmerv]

You are welcome, the reason you can’t go in is due to the depth of the portal wall, scale it on the z axis and you should be able to. Best to you !

[@roomi2222]

QUESTIONS Can we move inside the portal while walking through that portal door? Can we implement it inside the sphere with inverted normals to create an immersive experience? i.e Placing the portal foor at the center of sphere.

[@dilmerv]

That’s a good video idea :) thanks let me try it out !

[@brianchung9388]

@@dilmerv i got it to work by changing all inside portal layers to default layer after triggering a collision between the camera and the portal wall. This can be very intensive as I have to recursively go through each child node to change each layer. Is there a way to change the render object settings via script?

[@kalash9114]

any good practice for this ? @@brianchung9388

[@LeonFelipeCarrizosa]

Hi everyone. The background, inside the window renders in white when testing on Android. Is it possible to render it transparent? I mean, to see the camera image in the background? Thanks

[@LucasBenders]

You need to reorder the render features to make it work. The Mask need to be the first one, followed by ARBackground and InsidePortal as the last. I hope it helps someone!

You just saved my bacon! I've been troubleshooting this for like six hours. @@LucasBenders

Hello Charles, what version of Unity and URP are you using ?

@@dilmerv my unity version is 2019.4.8f1 and I use unity hub so just choose URP btw thanks for reply

More likely the version of URP is old, go to the package manager upgrade Universal Rendering Pipeline to 7.3.1
