Problem :
Black spots appear when Unity implemented in a transparent MP4 video player
Solution:
Unity comes with the use of shader remove black spots
1: shader code shown below
Shader "Unlit/NewUnlitShader" { Properties { _Color("Color", Color) = (1,1,1,1) //_MainTex ("Albedo (RGB)", 2D) = "white" {} _AlphaVideo("Alpha Video(R)", 2D) = "white" {} _Glossiness("Smoothness", Range(0,1)) = 0.5 _Metallic("Metallic", Range(0,1)) = 0.0 } SubShader { Tags { "Queue" = "Transparent" "RenderType" = "Transparent" } LOD 200 CGPROGRAM // Physically based Standard lighting model, and enable shadows on all light types #pragma surface surf Standard alpha // Use shader model 3.0 target, to get nicer looking lighting #pragma target 3.0 sampler2D _MainTex; sampler2D _AlphaVideo; struct Input { float2 uv_MainTex; float2 uv_AlphaVideo; }; half _Glossiness; half _Metallic; fixed4 _Color; void surf(Input IN, inout SurfaceOutputStandard o) { // Albedo comes from a texture tinted by color fixed4 c = tex2D(_MainTex, IN.uv_MainTex) * _Color; fixed4 _alpha = tex2D(_AlphaVideo, IN.uv_AlphaVideo); o.Albedo = c.rgb; // Metallic and smoothness come from slider variables o.Metallic = _Metallic; o.Smoothness = _Glossiness; o.Alpha = _alpha.r; } ENDCG } FallBack "Diffuse" }
2: Are you ready for the mp4 format video files, download and install well in advance QuickTime, import Unity among the video file from the Videoclip changed MovieTexture
3: Create a new Material material, will be prepared to use the material shader good to go, good video processing and dragged them
4: establishing plane model, X rotated 90 degrees, to establish a good model plane onto which the material to, control codes with video playback
5: the control code is as follows:
using System.Collections; using System.Collections.Generic; using UnityEngine.UI; using UnityEngine; public class Juasd : MonoBehaviour { public MovieTexture moveTex; // Use this for initialization void Start () { GetComponent<Renderer>().material.mainTexture = moveTex; moveTex.loop = true; moveTex.Play(); } // Update is called once per frame void Update () { } }
