Solved Cinema 4D R20 and Octane 3.08.5 attribute issue

Hi all,

I understand that this might not be related with Maxon, but thought of asking it anyway, as it may have been resolved by others or it can help others.

We are currently in the process of testing and deploying R20 and I'm testing all of our in-house plugins.
I've encounter an issue specific with Octane where it doesn't recognise the attribute IDs.

e.g.: Enabling the multipass of on the render engine.
AttributeError: 'module' object has no attribute 'SET_PASSES_ENABLED'

When debugging this by drag and drop the attribute into the console
It outputs OctaneRenderer[c4d.SET_PASSES_ENABLED], but throws the same error.

This is the first time I've seen it happen and not sure why it doesn't recognise it.

Please let me know if I do need to refer to Otoy instead.

Thank you in advance! :relaxed:

Probably, Octane saves its passes in a Scenehook. Unfortunately, Python is very limited in this regard.
Therefore, you cannot access its passes.

But this needs some clarification - I'll take a look into it within the next hours.

@mp5gosu
Thank you very much for coming back to me and your help! :relaxed:
Hmmm... Can't understand why Octane would have that change be made between versions, unless is been changed by Cinema in the first place, which I think it wouldn't be the case.

Thanks for looking into this and I will try to gather more information.

So I just installed Octane and took a look where Octane stores its passes. The general settings are stored directly with the VideoPost. The passes itself are stored at a separate branch as Post Effect Pass, see screenshot.
The settings on the right show the Node located under Post-Effects->Octane Renderer

Hi AndreAnjos,

Octane stores the passes settings in a VideoPost, and c4d.SET_PASSES_ENABLED is the ID for the checkbox highlighted in mp5gosu's reply.

Here's a snippet to print out the checkbox state, in the hope it helps

def check_octane_passes():
    renderSettings = doc.GetActiveRenderData()
    
    _vp = renderSettings.GetFirstVideoPost()
    oc_vp = None  # Octane VideoPost

    while _vp:
        if _vp.CheckType(1029525):  # Octane ID
            oc_vp = _vp
            break
        _vp = _vp.GetNext()

    if not oc_vp:
        return

    print "Octane Passes Enabled", oc_vp[c4d.SET_PASSES_ENABLED]

the error

AttributeError: 'module' object has no attribute 'SET_PASSES_ENABLED'

might imply that the Octane attributes have not been added at all to the c4d module. If that's the case you might need to make sure that your code is executed after the Octane plugin has been fully initialized

Hope it helps,
Paolo

@mp5gosu @pKrime
Thanks for your reply and findings!
Unfortunately my code is exactly like @pKrime example, so my problem is a bit weirder than I thought.

This makes more sense, but I know the plugin as loaded correctly, so can't be a initialisation problem (I think!).
Hopefully this will help:

@mp5gosu The Active Object Properties tool you screenshot, is it something you wrote or you can get it somewhere? looks very useful to me :relaxed:

Thank you both! :relaxed:

This is the "Active object dialog" that comes with Cinema 4D's SDK. Usually, you have to compile it yourself. But maybe some of the Devs can share a standalone version - it is useful even to pyDevs.

Thank you! I will try to compile it :)

Hi guys,

So after compiling the sdk examples and trying the Active Object Dialog that @mp5gosu showed me, the damn plugin run correctly.
I don't think I've done anything different to initialize Octane, but it's definitely working now after a few experiments.

So it doesn't happen again (and future reference), is there a way to force a plugin's initialization?

Thank you all again! :relaxed:

Edit: I've marked the thread as resolved, but hopefully we can get more insight to the matter.

Hi Andre,

you were too fast :relaxed:
I'm glad the issue got resolved.
When we were discussing this case here, we thought, if this might be related to the symbolcache.
See for example this thread: Dealing with Symbolcache

Of course we were only having an educated guess here and I was about to ask for more details.
Now, that the installation of another plugin (basically our C++ cinema4dsdk examples) brought some change, I'm almost convinced this was the culprit.

Cheers,
Andreas

Hi Andreas,

Thanks for your help and you are never too late! :relaxed:
That actually makes more sense.
Unfortunately I can't seem to replicate the issue again on my machine, as it seems that it's been working for all my updates.

I will have a look on one of my team machines when released and see if that could be the problem.

Thank you again! :+1:
