Transmit AOVS for transmission Alpha

[phillips.a.adam]

Hi,

Transmit AOVs doesn't seem to be giving me a transmission Alpha. I've set transmission in my HDRI to 0 as per the Arnold site advice but I still have a sold Alpha. Do you have any advice?

Does setting the skydome_light.camera visibility to 0 help?

@Lee Griggs not at all I’m afraid. 😞

Hi

Can you set up a simple scene, and if you cannot get that to work, post the scene.

[lee_griggs]

I posted an example scene here. Can you try it to see if it works for you?

Hi Guys, weird, I've set up a simple scene with just a ball and one material and it's working fine - no stress! It's not working with GPU rendering (seriously, why??). This chat forum would not let me upload my houdini file so I've made a folder in google drive.

Hi Adam

Unfortunately, Transmit AOVs is not supported yet on Arnold GPU.

Thanks @Stephen Blair i guess there's a fair bit of work left to do on the GPU
