Just wondering if there is a reason my flipbook previews get interrupted for no reason what soevere at random frames. This happens across multiple projects lately way too often. When i restart it at the frame it interrupted it opens the new frames into a differed separate Mplay, making the resuming unusable for MP4 quick previz.

I can export as PNG sequence but bringing that into AE and exporting is an extra step i don't wnat to take for quick previz.

Cheers,

This is killing my workflow, any idea guys? I literally have to keep my nose on the Mplay flipbook preview to retsrat it everytime it stops, it's far from ideal.

Hi Adriano!

I am having this same issue and what seems to work for me is to not just left click but right click on the Flipbook icon and choose Flipbook with New Settings. Just doing that seems to ensure Houdini renders the whole frame range, despite not actually changing any settings and the frame range remaining $RFSTART and $RFEND.

Additionally, I don't know if it is the case for you, but whenever this sudden stop happened, the second time Flipbook always rendered all frames for me, so perhaps you can face the issue deliberately (until you find a fix), start the first flipbook, immediately stop it and start a second one.

But of course, ideally you could open a bug report via any of the official channels to get better help.

Best regards,

THis behaviour is strange. I never had that before recently. I use to be able to just start a flipbook and keep working and do all buncha other stuff. Now if i click outside HOudini or dare to browse internet at the same time... i come back ot the flipbook and it stopped whenever. I'll try that fix. I rely more on openGL export though now when it comes to previz, because of that issue.

Definitely very strange but based on what you are saying, it might even be an operating system issue for you where Houdini doesn't get enought system resources, so more information would be required to find the root cause.

I am new to Houdini, but in Blender I always export viewport test renders as a PNG sequence and I have a stored procedure for PowerShell that quickly makes a video from the frames with ffmpeg.

Welcome to Houdini, Brother. You'll find that there aren't too many of those little bugs. And i think you might be right. Somehting off with my system. Not lack of resource as it's rather powerful and loaded with more than needed. But perhaps some drivers issues with the 5070tis gpus i have in there. Just too busy at the moment to fix that up. It appears nobody else is bumping into that little trouble so it usually means it's not a Houdini problem indeed.

Cheers,
