Hi guys, I just installed vray for houdini 18.5.351 on centos and everything seemed to install fine, however I can’t pull up the vfb or render. When I setup a scene and click these buttons, nothing happens. I don’t get any error messages or anything it just that no rendering occurs and the vfb does not come up at all. I tried running the python commands in the python terminal and the commands run and return with no error, however nothing happens, no render no nothing. Maybe I missed something on the install? Anyway, I tried everything I could think of and am looking to you for some help here now. Thanks. -Christian ---

This is the behaviour you get when VRay can’t get a licence for whatever reason. ---

I hope they change this behavior soon. You have now joined the club of people who have wasted a bunch of time troubleshooting this issue. I too, am a member of this club 🙂 ---

I guess you are running official V-Ray 5 for Hioudini. This problem fixed in latest builds, a message about missing license is displayed. ---

Hello @kien_nguyen , seems to work on my side. What OS you are using ? Is your V-Ray for Houdini installed via installer ? If you downloaded archive version, than how V-Ray is loaded via package file or through houdini.env ? When launching hython, is any information about V-Ray shown ?
