Hello,

I can't export frames using Houdini's flipbook. Houdini quits flipbooking after rendering first frame with this error message:

“Image file save error: Unable to create image …”

Flipbooking directly to MPlay is working, but I'm getting a lot of drop frames. For this reason it's a useless workaround exporting frames with MPlay to disk.

I've checked out every GL Mode in the “3D Viewports” preferences.

I also tried a fresh Houdini installation and I cleaned the Houdini profile in “users/my documents”.

UAC is turned off and I've all privileges to write to the desired destination folder.

Using a “OpenGL ROP” instead flipbook export is working (same destination folder), but I'm getting different results compared to the viewport display. So it is difficult to control how the written image looks like.

In H11 everything is working pretty well.

Any ideas?

Thanks a lot,
Peter

I did a quick test on another computer (similar configuration) and flipbook features also doesnt work.

Can maybe someone confirm this too?

Peter

Are there empty spaces in file path?

No, there aren't!

I'm sorry. I thought it was, but in H11 flipbook is not working also. The same issues as I described. Is this a limitation of the non-commercial version perhaps?

I've found a solution for the “file save error” problem. It has something to do with general output resolution limitation with Houdini Apprentice. Reducing the flipbook output size to 720x576 or below helps a lot , sounds sensible to me. ops:

But the drop frames issue when flipbooking to mplay still exists.

as Pittiplatsch suggested setting size/resolution on flipbook could save successfully
