Question HDRP Material - Opacity layer

Hey everyone,

something that might be super basic, but I'm struggling to get this right:

How do I get a material to have that opacity layer in HDRP Lit material?

Material so far:


Textures:


Result so far:

 

You have to pack you textures. The Opacity has to be in the alpha channel of the base color texture. The Mask Map consists of the metallic (R), AO (G), Detail Mask (B) and Smoothness (A).

 

Hero!

If anyone has the same issue:
1. Opened the basecolor texture in Photoshop
2. Added an Alpha layer
3. Added the Opacity layer as the Alpha layer
4. Save as Targa
5. Set material in Unity as transparant.
