Hello all! I can see the materials just fine in the scene view of my file. However whenever I try rendering out the scene in the render view the render view shows up as gray and I get the error Error: /home/dlee/vanilla/dv18.0/hfx/houdini/vex/include/voplib.h:1840:13-24 Error 1066: Call To undefined isshadingRHS. Is this calling to a cache that isn't on my computer?

I started getting this error recently. Any fix?

The only thing I was able to do was to build the scene again from scratch and reattach the shaders.
