Help/Advice: Adding Fog of War to lower layers of a custom Galaxy Background (like Real Space)

[King_of_Dale]

Hello guys,
I hope someone can help me here, especially since I'm still a total beginner. The following problem: I'm currently working on my own small submod for the various Star Trek mods. It changes the look of the galaxy background; see example picture No. 01. So far everything works perfectly. I used “Real Space” from Annatar as the base code to display 3D effects thanks to different layers (values from “position y=-3.000” to “position y=0.000”) in my file "grid_galaxy_particle.asset".

I came across the great mod “Improved Hyperlanes and Fog of War - Legacy”. It changes the FoW by completely covering the unknown galaxy background and planets/nebula in black. The FoW mod works perfectly with the vanilla galaxy background; see example picture No. 02.

Now I wanted to integrate this mod into my own. However, if I use my own submod or, for example, "Real Space", you can't see the planets/nebulae, but the galaxy is still visible in the background (i.e. everything under "position y=0.000"); see example picture No. 03.

Can the FoW be expanded at all for “lower” layers? If yes, can someone help me?


Here is the code from the file “terra_incognita.fxh”, taken from “Improved Hyperlanes and Fog of War - Legacy”:

PixelShader = {
Code
[[
static const float GALAXY_SIZE = 2000.f;
static const float TI_BLEND_START = 0.01f;
static const float TI_BLEND_STOP = 0.2f;
static const float TI_GRAY_BRIGHTNESS = 0.00f;

float Desaturate( float3 vColor )
{
return dot( vColor, float3( 0.212671f, 0.715160f, 0.072169f ) );
}

float CalcTerraIncognitaValue( float2 vWorldPos2D, in sampler2D TITexture )
{
float2 vTIUV = ( vWorldPos2D + GALAXY_SIZE * 0.5f ) / GALAXY_SIZE;
float vTI = tex2D( TerraIncognitaTexture, vTIUV ).a;

return smoothstep( TI_BLEND_START, TI_BLEND_STOP, vTI );
}

float4 ApplyTerraIncognitaValue( float4 vColor, float vBrightness, float vTI)
{
float Grey = Desaturate( vColor.rgb ) * TI_GRAY_BRIGHTNESS * vBrightness;
//Grey = TI_DARK + ( ( TI_BRIGHT - TI_DARK ) * ( Grey ) ) / 1.f;

vColor.rgb = lerp( vec3( Grey ), vColor.rgb, vTI );

return vColor;
}

float4 ApplyTerraIncognita( float4 vColor, float2 vWorldPos2D, float vBrightness, in sampler2D TITexture )
{
float vTI = CalcTerraIncognitaValue( vWorldPos2D, TITexture );
return ApplyTerraIncognitaValue( vColor, vBrightness, vTI);
}
