So this is the final pic of my render and how you can see my texture of glass on the french press went crazy,and i don’t have any thought about it,and how i need to fix it, i just go in shader window, separate part of object where will be the glass and add already existing texture of glass witch i use on the cup and i that it,i think problem in that the material of glass is separated from main part wrong,so if you have any thought it will be great if you will share it with me
It would help to see your node and UV setups. Perhaps strip out everything but the press and post a blend.
