Problem with using normal map for embossed texture in Arnold

Hi, all

I am an amateur Maya/Arnold user and mainly use it for product rendering.

Ultimately I would want to add an embossed texture to a glass object(aistandardSurface) similar to this

(For clarity, purposes change the glass texture to jade texture to show my problem better) I thought the easiest way to achieve this is via a normal map and map it using UV.
However, it seems to have some weird effect on the overall reflection of the object.
(top is without the normal map and bottle is with).

Above is how I lay my UV and my normal map(not perfect I know but I don't think it should affect too much.

Does anyone know how to fix this? Also, is normal map the best way to achieve my embossed effect on glass? Any Option is welcomed.


Thanks very much

I personally prefer displacement maps for realism.

Have you watched this video?

By the way, I did found out that happened. The problem I had was I have set my space for my normal map file to SRGB which should have been RAW, Just so any one wanted to know.
