Hey guys.
I have this weird glitch when I work with volumes.
Everything looks fine for a few moments, but then suddenly the display messes up.
These pics tell a better story.
My GPU is a nvidia 770GTX, so it should be able to handle it
Has anyone seen this kind of glitching before?
Thanks
Gerbrand

I am getting the same thing in 15.0.300 on GTX 970. Placing a light or 2 definitely shows this effect and it doesn't go away. Not sure if I should upgrade my drivers or if the viewport has an issue with volumes right now.

Yes I have this too on my GTX 960 with 359.00 driver and its really annoying. we should report to sidefx for this.

It's funny I see this post today.

I was doing some Python function scripting - adjusting part of an objects y translation parameter when I made a simple syntax error.

Removed the error and then not only the file seem corrupted but Houdini itself.

The main problem that developed is that I couldn't turn on and off the objects visibility.

In my file I tried adding a new object ( a sphere ) just to see if somehow my code messed up my object, but no I couldn't even turn visibility on to see the sphere and it was more than large enough and the viewport was suitable.

I decided to delete the new object sphere, then after saving the file, I closed it, and then closed Houdini.

When I opened Houdini again and then the file, the sphere I had deleted was now showing in the scene although its node was not listed in the Network Panel…so I opened the Network panel “full screen” so I could find the sphere node that should be there ( because the object was showing in the scene. ). As I just said, the node wasn't there but as soon as I collapsed the Network window to regular size to see the scene view again also, the sphere was now gone.

So this explained to me why when I was working on my Python code and had the syntax error, but corrected it…the original code I had working no longer did so…and I thought I had somehow corrupted my script code, when with further testing it appears something else is going on with the display.

I closed Houdini and opened a new file and tried with a new sphere object again and same problem ( not being visible/flagging display not having affect). So then I thought, no it's not just the one file.

So I uninstalled/re-installed Houdini and so far with new files I am able to set the display flags on objects…but still not with my file I was having problems with.

This is very weird, and to top it off you guys are having problems on the same day as well.

I last updated my driver about 3 weeks ago.

I'm using GTX 980 with driver 358.91

Guess I will try the update of 359

Hoping I don't have to copy and paste all that code from one file to another new one and duplicate the nodes and their names.

I guess I spoke too soon.

Even with Houdini re-installed…initially it would show objects in a new file…now it doesn't.

I guess I will have to report as bug or something.
