Help with earth glow

Hi
I've got this Earth Shader (LWRP) - It is rotating, has some clouds. It's scaled but it is child of the camera (perspective) so it doesn't move with player. I would like the edges to glow.

So I modified shader - add some code but glow depends on camera rotation / position. I don't want that.
I'm not good with shaders so I don't know how to resolve it.

Can you help me?

I've got this:


Want something like this:

Code (CSharp):

1. inline fixed3 AtmosphereColor(float3 worldSpaceDir)
2.                 {
3.                 fixed3 Fresnel1 = forwardVector;
4.                 fixed3 Fresnel2 = (1.0 - dot(normalize(worldSpaceDir), normalize(Fresnel1))).xxx;
5.                 fixed3 Pow0 = pow(Fresnel2, _AtmosFalloff);
6.                 fixed3 Saturate0 = saturate(Pow0);
7.                 fixed3 Lerp0 = lerp(_AtmosNear, _AtmosFar, Saturate0);
8.                 fixed3 color = Lerp0 * Saturate0;
9.                 return color;
10.                 }
11.  
12.                 v2f vert(appdata v)
13.                 {
14.                     v2f o;
15.                     UNITY_INITIALIZE_OUTPUT(v2f, o);
16.                     o.pos = UnityObjectToClipPos(v.vertex);
17.                     o.uv = TRANSFORM_TEX(v.uv, _MainTex);
18.                     o.normal = WorldSpaceNormal(v.normal);
19.                     float dist0 = length(o.pos.xyz - _CameraPosition * float3(1.0f, 1.0f, 1.0f)) * .025f;
20.                     dist0 *= -1; dist0 += 2.0f;
21.                     o.camDistance = pow(dist0, 2.8f)*0.2f;
22.                 //    o.screenPos = ComputeScreenPos(o.pos) - WorldSpaceVertexPos(v.vertex);
23.                     o.screenPos = ComputeScreenPos(o.pos);
24.                     return o;
25.                 }
26.  
27.                 half4 frag(v2f i) : COLOR
28.                 {
29.                     half4 color = tex2D(_MainTex, i.uv) * _Color;
30.                     color.a = 1.0f;
31.                     float3 screenPos = normalize(i.screenPos);
32.                     float3 worldNormal = i.normal;
33.                    
34.                     fixed rim = 1.0 - saturate(dot(normalize(screenPos), worldNormal));
35.                     fixed3 emission = (_RimColor.rgb * pow(rim, _RimPower) + AtmosphereColor(-screenPos));
36.                     color.rgb += emission.rgb * _RimIntensity;
37.                     return color *_Color * float4(float3(i.camDistance, i.camDistance, i.camDistance) *_CamColorDistModifier, 1.0f);
38.                     //return color *_Color  *_CamColorDistModifier;
39.                 }
40.                 ENDCG

 

You need to dot the view direction in world space with your world normal.
