Question by Velfet · Aug 13, 2021 at 02:34 PM · androidshaderunity ads

Image with outline shader material on canvas becomes invisible after showing ads on an android device

I tried using an outline shader from this website https://gist.github.com/mandarinx/f28931faa3c6a5378978a82c84d3dbcd

I have an image on a canvas with the outline shader material. The shader works fine in the unity editor, even after showing unity's ads in the editor. The shader also works initially on android devices, but after showing an ad, the image with the outline shader material becomes invisible. It's still there because I tried using the shader with a button and the button can be pressed, it's just not visible. Can anyone help me?

This is the outline shader I used:

// Upgrade NOTE: replaced 'mul(UNITY_MATRIX_MVP,)' with 'UnityObjectToClipPos()'

Shader "Custom/SpritesOutline" { Properties { //[PerRendererData] _MainTex("Sprite Texture", 2D) = "white" {} _Color("Tint", Color) = (1,1,1,1) [MaterialToggle] PixelSnap("Pixel snap", Float) = 0

     // Add values to determine if outlining is enabled and outline color.
     //[PerRendererData] 
     _Outline("Outline", Float) = 1
     //[PerRendererData] 
     _OutlineColor("Outline Color", Color) = (1,1,1,1)
     //[PerRendererData] 
     _OutlineSize("Outline Size", int) = 1
 }
 SubShader

     Tags
     {
         "Queue" = "Transparent"
         "IgnoreProjector" = "True"
         "RenderType" = "Transparent"
         "PreviewType" = "Plane"
         "CanUseSpriteAtlas" = "True"
     }

             return OUT;

             #if ETC1_EXTERNAL_ALPHA
             // get the color from an external texture (usecase: Alpha support for ETC1 on android)
             //color.a = tex2D(_AlphaTex, uv).r;
             #endif //ETC1_EXTERNAL_ALPHA

             return color;
         }

         fixed4 frag(v2f IN) : SV_Target
         {
             fixed4 c = SampleSpriteTexture(IN.texcoord) * IN.color;

             // If outline is enabled and there is a pixel, try to draw an outline.
             if (_Outline > 0 && c.a > 0.1f) {
                 float totalAlpha = 1.0;

                 [unroll(50)]
                 for (int i = 1; i < _OutlineSize + 1; i++) {
                     fixed4 pixelUp = tex2D(_MainTex, IN.texcoord + fixed2(0, i * _MainTex_TexelSize.y));
                     fixed4 pixelDown = tex2D(_MainTex, IN.texcoord - fixed2(0,i *  _MainTex_TexelSize.y));
                     fixed4 pixelRight = tex2D(_MainTex, IN.texcoord + fixed2(i * _MainTex_TexelSize.x, 0));
                     fixed4 pixelLeft = tex2D(_MainTex, IN.texcoord - fixed2(i * _MainTex_TexelSize.x, 0));

                     totalAlpha = totalAlpha * pixelUp.a * pixelDown.a * pixelRight.a * pixelLeft.a;
                 }

                 if (totalAlpha == 0) {
                     c.rgba = fixed4(1, 1, 1, 1) * _OutlineColor;
                 }
             }

             c.rgb *= c.a;

             return c;
         }
         ENDCG
     }
 }

}

This is the script I used on the image object:

using System.Collections; using System.Collections.Generic; using UnityEngine; using UnityEngine.UI;

namespace Nagih { public class SpriteOutline : MonoBehaviour {

 [SerializeField] private Color outlineColor;
 [SerializeField] private Color DefaultImageColor;

 [Range(0, 10000)]
 [SerializeField] private float outlineSize;

 [SerializeField] private SpriteRenderer SpriteRenderer;
 [SerializeField] private Image Image;
 [SerializeField] private RectTransform RectTransform;
 [SerializeField] private bool HasOutline = false;


 void OnEnable()
 {
     
     if(HasOutline == false)
     {
         HasOutline = true;
         UpdateOutline(true);
         Debug.LogWarning("Update outline...");
     }
     
     
 }


 private void UpdateOutline(bool outline)
 {
     
     if(Image != null)
     {
         Image.material = new Material(Image.material);
         Material test = Image.material;

         test.SetFloat("_Outline", outline ? 1f : 0);
         test.SetColor("_OutlineColor", outlineColor);
         test.SetFloat("_OutlineSize", outlineSize);
         test.SetColor("_Color", DefaultImageColor);

         //Reset the color of the image
         Image.color = DefaultImageColor;
     }



     

     
 }

}

}
