AiStandardSurface TransmitAOV behavior

[kenny_chang]

Hello,

Is it an expected behavior that with Transmit AOVs checked on in combination with Thin Walled, it will affect the alpha values.

We understand that Transmit AOVs affects the alpha based on the transmission gain, but want to confirm if this is an expected behavior when transmission gain is set to 1 but "thin walled" is checked on, that the alpha becomes transparent.

Hi,

I have the same problem. I know that if I uncheck transmit aov and/or thin walled, alpha channel works in the right way...but I need to use Transmit AOV and I need thin walled to avoid ior deformation to the eyes.

This is an example: 

How can I solve this?

Thank you for your support
