Is NRD limited to 16 bits float textures?

[StudenteChamp2]

From NRD.hlsli:

    // X => IN_DIFF_RADIANCE_HITDIST
    // X => IN_SPEC_RADIANCE_HITDIST
    float4 RELAX_FrontEnd_PackRadianceAndHitDist( float3 radiance, float hitDist, bool sanitize )
    {
      if( sanitize )
        {
          radiance = _NRD_IsInvalid( radiance ) ? float3( 0, 0, 0 ) : clamp( radiance, 0, NRD_FP16_MAX );
          hitDist = _NRD_IsInvalid( hitDist ) ? 0 : clamp( hitDist, 0, NRD_FP16_MAX );
        }

     return float4( radiance, hitDist );
    }

What will happen if i use 32 bits float textures?

You can use FP32 if your radiance passed to NRD <= NRD_FP16_MAX.

Internal processing for radiance is FP16. But when creating NRD resources, including internal ones, you can replace RGBA16f to RGBA32f without problems. It can be done by modifying g_NRD_NrdToNriFormat, if you use the NRD integration layer.

Exellent thank you <3
