We have noticed an unexpected behavior about the thin film when using it with a specular and transmission. It seems that when the thin film is enabled the transmission is not handling the TIR anymore. Is this the expected behavior ?
Here some images from Maya Arnold (MtoA 4.0.2 - 46d4a92e (master) - Feb 13 2020 03:01:44) that shows the issue :
Here we can see that increasing the depth transmission change nothing when the thin film is enabled :
And if we are visualizing this LPE : CTT+TL which correspond to internal reflection we have the TIR for the case when there is no thin film for the depth 3 and 4 but there is nothing when the thin film is enabled.
