steel verge
I've been working on screen space reflections and oddly I get good reflections when the camera is almost perfectly straight, but I have stretching issue, and close up reflections are almost entirely missing.
```bool RayMarch(float3 viewPos, float3 reflDir, out float2 outRayUV)
{
outRayUV = float2(0, 0);
bool hit = false;
float3 rayPos = viewPos;
float currStep = stepSize;
for (int i = 0; i < 32; ++i)
{
rayPos += reflDir * currStep;
float4 rayProj = mul(proj, float4(rayPos, 1.0f));
rayProj /= rayProj.w;
float2 rayUV = rayProj.xy * 0.5f + 0.5;
rayUV.y = 1.0 - rayUV.y;
if (any(rayUV < 0.0) || any(rayUV > 1.0))
{
return false;
}
float sampleDepth = ReconstructViewPos(depthTex.Sample(pointSampler, rayUV).r, rayUV, inverseProj).z;
float depthDiff = rayPos.z - sampleDepth;
if (depthDiff > thickness)
{
hit = true;
outRayUV = rayUV;
if (currStep < 1)
{
break;
}
rayPos -= reflDir * currStep;
currStep *= 0.5;
}
}
return hit;
}
float4 ps_main(VSOut input) : SV_Target
{
float2 rayUV;//final coordinates to sample from
float4 rmeao = rmeaoTex.Sample(pointSampler, input.texUV);
float roughness = rmeao.r;
float metalness = rmeao.g;
clip(metalness - 0.01);
float3 viewPos = ReconstructViewPos(depthTex.Sample(pointSampler, input.texUV).r, input.texUV, inverseProj);
float3 normal = normalize(2.0f * normalTex.Sample(pointSampler, input.texUV).xyz - 1.0f);
float3 reflDir = reflect(normalize(viewPos), normal);
float3 outColor = float3(0, 0, 0);
bool hitFound = RayMarch(viewPos, reflDir, rayUV);
if (hitFound)
{
outColor = lightTex.Sample(pointSampler, rayUV).rgb * metalness;
}
return float4(outColor, 1.0f);
}```
