I simply would like to apply the Global Volume only on specific layers but I probably misunderstood how it works.

Environment & Inspectors

• GameObject\ Main Camera - Volume mask\ Background

• GameObject\ Global Volume - layer\ Background

• GameObject\ Background_terrain - layer\ Background

• GameObjects\ [All other game objects] - layer\ Default

This is the result: The cloud and the platforms outlined in red are Default layers while the rest is the Background.

Since the guide says that some effects are applied to the entire camera anyway, I tried about ten but they all apply to the entire camera render. I left only the DOF because it is the clearest to show you the result.

What am I doing wrong ?

Thank you !
