All the same, this problem appeared again!

Attached is a small video from the screen demonstrating the problem of a black "empty" viewport.

What is this problem and how can I solve it?

Review the System requirements from the Support link up above on this site. Does your computer meet the minimum requirements to run Houdini?

I can't see your video, but is it possible that your viewport distance display is not large enough to see your scene? I've run into that issue before.

I get this every once in a while as well and I don't think the hardware is to blame.
Toggling back and forth between the different lighting modes, or jumping in and out of different objects will often snap Houdini out of it though.

Absolutely, because everything worked yesterday.

If you can watch the video, it will be clear that the object is right in front of the camera and the problem is not only that - but that the viewport is empty - there is not even a grid there.

If it's not difficult, please tell me what exactly are you doing to fix this houdini glitch?

Try toggling between these buttons. Sometimes it sorts itself out. If not, try going from inside your SOP, back out to obj level and maybe inside a different object. Ctrl+b to maximize/minimize can also help. If all else fails, restart Houdini.
Unfortunately Houdini's OpenGL viewports aren't as robust as they could be. There are a number of issues like this: lighting going wonky, object visibility getting stuck, selection highlighting doing wacky stuff...

did you try to change viewport clipping ?
adjust the range properly according to your scene scale and maybe select the "Hide other object" option as well



you can try to close the Scene View and reopen a new one, sometimes it can fix some issues
