Does anyone have an idea how to fake "live" height to normal map effect in Photoshop?

I know there is an old embos trick but I would like a live preview like bevel and embos on the fly workin on a height image without transparency.

Have you tried Nvidia Texture Tools?

Did you try Filter>3D?

If those filters don't seem to work right, it's mostly due to the fact that Adobe is in the process of removing all features from Photoshop that use the 3D engine.

In that case you can install Photoshop 2021 (ps ver 22.2) from the Creative Cloud Application Manager and the 3D features should work in that version provided your graphics card works with Photoshop.

Thank you Jeff for your suggestion. Filter>3D is weird and pretty useless thing in Photoshop IMO. Producing incorrect and blurry looking normal maps. How can I get linear resonse from it doing mathmetically correct height-to-norml conversion? I always have to apply sort of crazy compensatory gamma shift first and nevertheless it's still blurry with soft edges. A critical disadvantage even for just a preview.

It's also not "live" . You can't paint / edit height image and see what's coming into normal map until you save smart object after each brush stroke . Whish we would have "lighting" live filter like in Affinity photo where it's possible to have pretty correct normal map on the fly ( also needing gamma correction if not in 32bit mode although). .
