GTX570 newest driver.
win7 x64
opengl 3.2 viewport mode with “High Quality Light shading” turned on

“Mantra surface model” applied to ploygon sphere.
tested with all kinds of lights

the object surface disappear.
I do something wrong or its a bug ?

The same is happening here as well, GTX 560Ti 1GB (in all GL modes. Fine in H11 mode)

Other people have reported such happenings and it seems to be down to the openGL within Houdini.

Yup same here, GTX570.

Some one can confirm if its happening in Linux and OSX ?

it's also not working on Ubuntu 11.10. ( quadro fx 3700 )

Osx has the same problem and in h11 mode the light gizmo is casting shadows

“Side Effects Support Ticket: #5818

Hello James,

This is a known bug, we are working on fixing it…
Cheers,

Support

If it matter's I'm seeing the same thing - just got a new Quadro 4000 card, and the latest Windows 7 drivers. Bummer
I do now have the option of selecting OpenGL 3.2 for the viewport (which I've selected and restarted Houdini 12), but no lucking getting the Advanced lighting to work.

This is from the Help dialog:

Platform: windows-x86_64-cl15
OpenGL Vendor: NVIDIA Corporation
OpenGL Renderer: Quadro 4000/PCIe/SSE2
OpenGL Version: 4.2.0
OpenGL Shading Language: 4.20 NVIDIA via Cg compiler

Same problem and other opengl modes shows constant white geometry and h11 gizmo shadows as well, GTS 250.

I would like to ask for an update of all of you guys

For me, nothing changed here with the new production build update for houdini 12 where they said they had furthermore improved the viewport. Is that right? What about your systems guys? Working now when switching to HQ or still broken?

SideFx, please fix this. It has been a very cool feature in H11 where it worked perfectly. You promised a “enhanced viewport” in H12 but all I see is either a mess, or nothing, or blackness, or white objects as soon as I try to use advanced vieport features.

Hope you guys at sidefx manage to fix this! It would be great!

I tried one of the newer daily builds and it worked better.

which one in particular? Just to clarify and have something to compare to.

EDIT: just tried the new daily build and it is still broken. I've written a support request to SideFx. Now waiting for their reply.
