Reflection with transparency - Maya Arnold

Hey, guys!


Hope you are all doing well and safe.


I have a question regarding the Arnold render, I've tried this in a few ways but not sure if this is possible. I'm trying to create a shader that makes a reflection of the objects in the scene but leaves a transparent background if there isn't anything else on the scene. The idea is to render some models in high resolution for print and have a nice reflection under those. Unfortunately, every time I try something new, the plane does keep a black background (some prints will be a black background but others will switch colors). I have tried a few configurations but no luck so far with the standard surface.


Any ideas from the community on how this can be achieved, if possible?


Thank you ๐Ÿ™‚

I feel a bit silly but I figured it out hahaha


So, the aiShadowMatte has the indirect specular option which makes the effect I was looking for, I didn't know about that particular setting (focused too much on the standard surface). In case anyone is trying the same thing, this link below will be a great ref:
