# Project 360 video on the inside of a iso sphere / polygon sphere

I'm creating a game in Unity. I have a iso sphere or polygon sphere, and I want to project a 360 video on the inside of the polygon sphere.

I've learned thow to put a 360 video on the inside of a sphere, following this thread, but how can I do it inside a polygon sphere, since the 360 video was created based on a sphere but not a polygon sphere?

Shader "Flip Normals" {
Properties {
_MainTex ("Base (RGB)", 2D) = "white" {}
}

Tags { "RenderType" = "Opaque" }

Cull Off

CGPROGRAM

#pragma surface surf Lambert vertex:vert
sampler2D _MainTex;

struct Input {
float2 uv_MainTex;
float4 color : COLOR;
};

void vert(inout appdata_full v) {
v.normal.xyz = v.normal * -1;
}

void surf (Input IN, inout SurfaceOutput o) {
fixed3 result = tex2D(_MainTex, IN.uv_MainTex);
o.Albedo = result.rgb;
o.Alpha = 1;
}

ENDCG
