Arnold GPU render transparency alpha

Hey!!

First, sorry for my english and if you don't understand everything.. ^^

I'm having an issue with GPU render on Arnold. Im trying to have a transparancy glass in a PNG file that I will use later in photoshop where i'll be able to change the background etc.. It works fine on CPU but not on GPU with the same settings. On GPU it takes the background and my object has a black background and no alpha. I join 2 screenshots to explain a bit more the problem.

Can someone help me? alpha-cpu.jpgalpha-gpu.jpg

Tested your file and it is true, there is no alpha when using the GPU.

No alpha where? In the rendered PNG file?

This is because Transmit AOVs is not supported on the GPU yet.

Is there a way to do it ? Without CPU ?
