    There is one more issue currently with 17.5.173 and HtoA4, the old workaround for opacity inside the Quixel Arnold HDAs is no longer working in HtoA4, the best solution for the time beeing is that if the object you are sending over does not have a opacity map, just disconnect the opacity connection in the material.

    yes I confirm for env. Now it works. For opacity its right if the opacity is empty it need to break the connection. thanks

    The Houdini.ENV file issue was a bug in Houdini that has been fixed 17.5.204 and above.

    Houdini 17.5.360 here, still same problem. I have redshift installed, not arnold.  I have tried both ideas with no success (moving the Quixel line before the RS line, the quixel megascan menu disappers from houdini ). Please help!

    Here is the error:

    EDIT:  It seems to happen only with Mushrooms, and Button Mushrooms, at least among the models I have... Thanks!

    EDIT2:  re-downloaded asset and problem seems fixed. Thanks!
