Configuring AR Foundation 3.0.0-preview to work with LWRP or URP

THX TODDS

 

Thanks!

 

Amazing. Thanks, I look forward to testing this

 

Anyone got it to work with 2019.3.0b1 + AR Foundation 3.0? I'm getting blue screen.

EDIT: OK. I got it to work on a fresh project. However I have a problem converting from a existing one. Any tips to look for?

 

Ok I got it to work. The problem was that the Canvas was displayed in "Screen Space - Camera" mode with a separate camera. After switching to "Overlay" all is fine.
Would be nice of you guys to place a simple warning on this post that it does not work when there is a second camera e.g. for canvas rendering. This would spare me and future users a few hours of battling as it doesn't throw any warnings nor errors.

On a side - LWRP is great (thanks for finally integrating it with ARF), but still we should have an option for a separate canvas camera to e.g. to render 3D objects.

 

While easy to set up, a little frustrating we have to do this and doesn't work for our LWRP use case. We are using a custom SRP in the project folder (it's a very slight modification of the LWRP), so even though the fix should still be relevant to our SRP, its not working since it is looking for shaders hardcoded to a path in the package manager


Trying to figure out the least hackiest work around, but any suggestions from the LWRP or ARFoundation devs would help

 

Just updated to this, I seem to be coming across a gamma issue. My project is linear but my camera feed is definitely having gamma applied to it. Any help would be greatly appreciated - I'm a colossal noob at all of this stuff

 

Click the "custom background" checkbox on the AR component.
Add a material that has this linear shader:

Camera will be crisp again

 

I do not get the option to add "AR Background Renderer Feature" to the Renderer Features of my ForwardRenderer. The Project was created with LWRP and the ARFoundation Package ist installed.

Any idea how I can fix that?

 

Just found it. The project still loaded v2 instead of v3-preview.

 

Bloody legend, thank you very much!

 

Hi. When creating a build for Android (ARCore), the camera background is always black. I managed to solve this problem by replacing the shader.

Code (CSharp):

1. Shader "ALEXWICK/ARCore/ARBackground(Linear)"
2. {
3.     Properties {
4.         _MainTex ("Texture", 2D) = "white" {}
5.         _UvTopLeftRight ("UV of top corners", Vector) = (0, 1, 1, 1)
6.         _UvBottomLeftRight ("UV of bottom corners", Vector) = (0 , 0, 1, 0)
7.     }
8.  
9.     // For GLES3
10.     SubShader
11.     {
12.         Pass
