Hi I have problem with digital asset and parallax occlusion when I use normal sop or boolean sop. First on video is without normal sop second with.

Normal sop change tangent and binormals

Ok I do some tests this problem is everytime when mesh has normals its will by becose houdini has different AXIS system from unreal?

OK I find solution after X hour experimenting Project Setting>Houdini Engine>Static Mesh Build Settings>Recompute Tangents>Always

oh when recompute tangents i loos normals from houdini
