AOV Light Group + Transmission problem

Hi,

 

I have a problem I can't figure it out...

I'm not able to havethe same result between my transmission AOV and my transmission per light AOV.

My scene is built like this (cf snapshot)

I create a sphere

I assign a glass shader on it (I use the preset glass)

I create a light placed behind the sphere, I set an AOV Light Group called RefractLt

I create the rendervars RGBA, transmission and transmission_RefractLt

I create render vars, render product, render settings (using arnold_rendersettings HDA or solaris nodes doesn't solve my problem)

As you can see just below, my RGBA and Transmission AOV are fine but the transmission_refractLt isn't producing the result that is expected, which is transmission_refractLt AOV should be similaire to transmission AOV.

I'm using Houdini 19.5.682 with HtoA 6.2.3.1 (Arnold 7.2.3.1) (.hip and snapshots attached to the post inside the .zip file)

 

Has anyone ever had this problem ?

 

Thanks
