Animation doesn't render

[BobJantenCate]

Hello Paul,

I sometimes get this problem when trying to render out an animation via the Octane plugin the animation doesn't start rendering.
Mostly this happens with a larger scene (polycount of 10 million). When checking Windows Taskmanager the CPU keeps spiking continuously
(see Attachment). It keeps doing this and as a side effect Modo freezes. Any idea what causes this? Restarting the computer and starting up modo
again seems to 'fix' it most of the time. But then eventually the problem arises once more.

Modo v12.2 and v13.0
OctaneRender for Modo 4.04.0.145
Windows 10
Amount of Ram: 64 GB
Graphics Card 2x Nvidia GeForce GTX1080 8GB
Nvidia driver version 430.64

CPU spiking

OctaneRender Animation bar stays like this

Hi Bob

This is not a problem I have seen before.

Does it happen on all scene you try to render, or just that one?

What are you r Max Samples set to? Is it possible the render is happening too quickly and the plugin is getting confused?

Are any render image files being saved?

Hi Paul,

It's this scene in particular (although I haven't tested it on other 'large' scenes yet). On the smaller scenes with much less polygons I haven't
encountered the problem.

Max Samples: 1200, so it's not that the renders are happening to quickly.

No render images are being saved.

There is a 'solution' though (simple workaround is a better way to describe it I guess). I took notes of my steps and it turns out
that the CPU spiking happens when I do the following:

1. I hit the 'play' button (render button) to check if the shot is good to go for rendering the animation.
2. After that I hit the animation button to render out the image sequence and the problem occurs.

Now the workaround is:

1. I hit the play button, check the shot
2. I hit the stop button
3. And now when I press the animation button it all renders like it should.

Hi Bob

Thanks for that info.

If you are able to send me the scene that caused this issue, I can investigate further.

Thanks

Hi Paul,

I am and I will. I'll send it to you today.

Hi Bob

Thanks for sending through that scene. The issue was that when starting the animation while Octane was already rendering, the plugin was reloading all the texturemaps, and there was a cyclical reference in the scene which was causing that process to loop indefinitely. This is fixed in the next release.

Thanks

Hi Paul,

Ah, thanks for that! And you're welcome
