I am running into this problem as well. I have Arnold, and when I installed GameDev tools all my shaders went away. It happens with new scenes as well as existing scenes. I checked my $PATH and $HOUDINI_PATH vars and they seem to be loading all the proper stuff from a glance.
#PATH = “$PATH;C:/Users/User/htoa/htoa-5.1.0_r9289183_houdini-18.0.348/htoa-5.1.0_r9289183_houdini-18.0.348/scripts/bin”
#HOUDINI_PATH = “C:/Users/User/htoa/htoa-5.1.0_r9289183_houdini-18.0.348/htoa-5.1.0_r9289183_houdini-18.0.348;&”
