like this,and it's becam inconceivably slow on my PC,Help~~~~~~~

:roll:

still need help~~

It would really help everyone If you could actually post up some details like OS , graphics card & driver .Houdini version would also be useful .Basically the more information the better .Posting up a picture and expecting everyone to play guess the error is not a lot of fun. Have you not thought of contacting support seeing as you use Houdini Master ?

I'd delete your $HOME/houdini9.5 directory and restart Houdini, to begin with.
