AOV costume problem, objects with opacity mask not working

Hello everyone, i have a problem my object with opacity mask in a custom AOV, the opacity mask not working and i don't know why!, i created a costume AOV then i use a standarsurface with opacity mask then i created a aiUtility (normal) and plug in a costume shader, that's it. With default AOV working fine, but costume AOV i have this opacity mask issue Thank you so much for your help greetings from Lima - Peru

Can you post a screenshot of the shader tree for the custom AOV?

Use an aiWriteColor shader for the aov.

aiWriteColor has a Blend parameter that takes care of blending the opacity into the custom

For the Default Shader, use an aiWriteColor instead of aiUtility.

Then connect a Utility to aiWriteColor.input

Set aiWriteColor.Name to your custom aov name

Stephen, thank you so much for your help, finally working i'm happy for that. although, i plug in the beauty, not in the input slot, is that right? it's correct? so far, i don't have any troubles for that, it's working fine for me :), thank you sensei.
