do i have to hijack it myself on photoshop or is there any tips to have it well ?

You either have to activated alpha transparency or assign a alpha texture as a bw .png file (see the one below as an example).

thanks for answer.
But sorry i can’t find the menu you show me higher
i only have that

For V-Ray, you will find it under opacity
