VRay VFB window problem

Hi,

I have a recurring problem with the VRay VFB disappearing as soon as it appears. If it’s initially off, I check the ‘Use VRay VFB’ under the render settings. When I click on the ‘Show VRay VFB’ button, the window appears and vanishes immediately. Getting the VFB window seems to be purely a matter of luck most of the time. Any idea why this is happening, and how I can fix it?

Thanks!

Never mind.. I just noticed the sticky in this forum :slight_smile: Annoying problem though.. I’ve begun to rely heavily on the VRay VFB, hate it when this happens
