opacity map in HDRP shader graph

[Thibault_potier]

Hi

I’m working with the HDRP/AutodeskInteractive shader : I am modifying this shader to fit my needs.

Right now I’m trying to use an Opacity Map to deal with transparency. Here is what I added in the shader so far :

But it doesn’t work enabling / disabling the boolean doesn’t trigger anything and no matter what I use as value for the color or the texture, it never goes transparent. Am I misanderstanding the way it should works ?

Thanks for your time and help <3

Found it !

I just had to set the shader surface type to : “Transparent”
