Hi, I just installed Houdini 20.0.547 and Vray. They worked just fine. Then I opened Houdini 19.5.403 and Vray shelf icons were missing with this message. I still can render with Vray though.
Have anyone experienced this before? How can I fix this? Thank you.
I have had similar problems and wasn`t able to figure it out with support at the time. I think it is related to houdini not scanning all the nececairy files depending on how you open houdini.
Can you check if you have your env file for 19.5 ?
