It seems we forget to transform the object space normal or tangent to world space for SPIRV version

The following code is from ps_main of RasterizedGBuffer.hlsl

#ifdef SPIRV
    GeometrySample gs = (GeometrySample)0;
    gs.instance = t_InstanceData[g_Instance.instance];
    gs.geometry = t_GeometryData[gs.instance.firstGeometryIndex + g_Instance.geometryIndex];
    gs.material = t_MaterialConstants[gs.geometry.materialIndex];

    gs.texcoord = i_texcoord;
    gs.objectSpacePosition = i_objectPos;
    gs.prevObjectSpacePosition = i_prevObjectPos;
    gs.geometryNormal = normalize(i_normal);
    gs.tangent.xyz = normalize(i_tangent.xyz);
    gs.tangent.w = i_tangent.w;
#else
    GeometrySample gs = getGeometryFromHit(g_Instance.instance, g_Instance.geometryIndex, i_primitiveID, i_bary.yz,
        GeomAttr_All, t_InstanceData, t_GeometryData, t_MaterialConstants);
#endif

Within the getGeometryFromHit, we transform the normal and tangent from object space to world space. But for SPIRV version, we keep using the object space normal and tangent.

Start in the ps_main code path of RasterizedGBuffer.hlsl and compare the SPIRV branch with getGeometryFromHit. Trace how the non-SPIRV path transforms the normal and tangent from object space to world space, then verify that the SPIRV path produces the same spaces for both values. Done means the SPIRV version no longer retains object-space normals or tangents.
