Htoa 6.0.2.0 in Houdini 19.0.383, opacity and transmission cannot render at the same time issue

Heyy I have some trouble when I try to render two different object with one opacity-activated material & one transmission-activated material in the houdini scene, like rendering a 3D plant (connected with opacity map) and water (transmission on).

 

Arnold 6.0.2.0 in Houdini 19.0.383 cannot render these two material at the same time, but working nice when disable one of them. Arnold just stop render with no any update in IPR when I try to render these two object at the same time. Even I click the "render to disk" button, it failed to generate a complete render file and I got a broken file.

 

So I wonder is that a common bug in this arnold version. Cheers!

Please try with at least HtoA 6.0.2.2, which is based on Arnold 7.0.0.3

Arnold 7.0.0.3 has this fix, which in the original reports was described a lot like your problem.
