Portal Shader becomes cross-eyed when using VR

Hi all,
Im having a problem getting this shader working with VR, anyone know how i can fix it?

I am trying to make a Portal effect, used Brackeys tutorial as a start off point. I originally was using a first person character then decided that it would be pretty cool in VR. However, Once i added the OVR player controller it makes the portal look as if you are crosseyed? Anyone know how i can fix this?

This is the shader just now:

Code (CSharp):

1. Shader "Unlit/ScreenCutoutShader"
2. {
3.     Properties
4.     {
5.         _MainTex ("Texture", 2D) = "white" {}
6.     }
7.     SubShader
8.     {
9.         Tags{ "Queue" = "Transparent" "IgnoreProjector" = "True" "RenderType" = "Transparent" }
10.         Lighting Off
11.         Cull Back
12.         ZWrite On
13.         ZTest Less
14.         LOD 200
15.        
16.         Fog{ Mode Off }
17.  
18.         Pass
19.         {
20.             CGPROGRAM
21.             #pragma vertex vert
22.             #pragma fragment frag
23.            
24.             #include "UnityCG.cginc"
25.  
26.             struct appdata
27.             {
28.                 float4 vertex : POSITION;
29.                 float2 uv : TEXCOORD0;
30.             };
31.  
32.             struct v2f
33.             {
34.                 //float2 uv : TEXCOORD0;
35.                 float4 vertex : SV_POSITION;
36.                 float4 screenPos : TEXCOORD1;
37.             };
38.  
39.             v2f vert (appdata v)
40.             {
41.                 v2f o;
42.                 o.vertex = UnityObjectToClipPos(v.vertex);
43.                 o.screenPos = ComputeScreenPos(o.vertex);
44.                 return o;
45.             }
46.            
47.             sampler2D _MainTex;
48.  
49.             fixed4 frag (v2f i) : SV_Target
50.             {
51.                 i.screenPos /= i.screenPos.w;
52.                 fixed4 col = tex2D(_MainTex, float2(i.screenPos.x, i.screenPos.y));
53.                
54.                 return col;
55.             }
56.             ENDCG
57.         }
58.     }
59. }

 

Hey @AlanG97 , we had the same idea ( following the brackey tutorial in VR ).
I succeeded to display a correct rendertexture through the portal but I still have a parallax distorsion.
I'm stuck one step before you but this could still be useful ->

Hi @Untoldecay , I downloaded your portal project from the link you provided and when i ran it, it still had the cross eyed problem I am explaining. How have you got your VR settings set up? Are you using monoscopic or stereoscopic, single pass or multiPass, etc?

 

Hey @AlanG97 I'm using MultiPass stereo rendering method and on the OVRcameraRig, I have enabled the "use one per eye" setting. In Other settings under Player settings my minimum level API si Android 5.0, and the target API level is set on the highest installed.

I hope this will help.

 

What VR headset are you using?

 

Oculus GO.
I mentioned it in the title of the post I shared to you.

I hope my process will help you at least.
Did you set 2 rendertextures overlapping with one camera per eye in your project?
