Cinema4D version 2022.1.1-R6 (Obsolete stable) 08.07.2023 Tweet

I spoke too soon!

I updated the Octane plugin to 2022.1.1 R2 and the bug came back, with C4D freezing with a "mat checkAndUpdate STARTED" message on the bottom of the window.

I went back to Octane 2022.1 [R10] and no crash

Then installed 2022.1.1, same freezing "mat checkAndUpdate STARTED" every time

So I reinstalled 2022.1 [R10], hit the render button, rendered a ton of frames no problem.

So something that changed between 2022.1 [R10] and 2022.1.1 has brought this bug back, might help in pinpointing what's causing it!

Update:
I have more information that'll help!
https://drive.google.com/file/d/1365pa6 ... sp=sharing
This scene right here freezes octane/c4d (even 2022.1 [R10]) as soon as I hit render to picture and it renders 1 frame. If I open the file but change the child cloners to "render instance" instead of just instances, then hit render, I can render multiple frames. If I then switch the child cloners back to plain instances, then I can render multiple frames with those.

So this bug happens when the file is rendered right away upon opening, but if I switch the cloners to render instances, render, then switch them back the bug disappears. I've done this sequence 3 times now with the same results, I think that should help!

Any idea what else could be causing the "mat checkAndUpdate STARTED" freezing? Because I get it with other scenes at random times that I can't reproduce

Are you keeping another scenes and playing with these also? Crash happened a few time if I render/tweak another scenes before render this.

Hi Aoktar,

We seem to be getting an inconsitent issue with octane finishing renders since updating to the latest version of cinema 4d (2023.2.0).
Ive attatched a photo, it seems to be freezing octane completely when it tries to save the frame if the AOV's are enabled.
It sticks on displaying Custom AOV pass, this could be any of the AOV's it seems to fairly random.
This will happen on certain files then suddenly fix itself to then return again.
We tried downgrading to R1 also the previous stable R10 but it still has the same issue which would suggest a compatabilty issue with the new cinema.

It may be related to C4D version. Plugin built over that, so test it with R8 and give feedback: https://render.otoy.com/customerdownloa ... R8_win.rar

Hi Aoktar,

Thanks for the quick reply on this, I managed to get the crash conistant one of our files then installed R8 but unfortunately the issue still remains.

Then please send me your scene to let me test it

Hi Ahmet,

I am having the issues with rendering to picture viewer C4D 2023.2 as well. I have all the details and reports in the bug report post I made. I was able to isolate it to denoising passes in my case. I have tried clean installs of C4D, and multiple octane versions.

There are videos and scenes in that post:

Hi Ahmet,

I have a question, why can't we render a spline with an octane object tag, when the spline is a primitive (non editable) ?

Thanks

Hello,
It seems working fine for me... Have you tick "Render as hair"?
Then you can drag it to a Null even if you don't have the Hair tab anymore.
