Applying Materials to Nulls OK in Octane?

It is quite common in Cinema to apply a material to a parent null, and have that null send down the material to its children (unless they have their own materials assigned, of course.) However, I have noticed that this method doesn't work reliably in Octane, particularly with SubD objects. I can get around that, but I noticed in my most recent crash that Octane was complaining it could not get a null with the material. Is this considered bad practice in Octane?

Yes. it counts until reach another materials overwrite on child objects. If you post a sample we can see. It's better to posting just some words.

It show plugin is trying to set an undefined pin. But this is not a critical problem to give a Cuda error. You should find a line which contains "Cuda error......".

Thanks, Aoktar. As I said, this issue is causing Cinema to hang, and since Octane does not write out a log, when I restart Cinema, there is no information to recover
The only option I see to write out a log is if you can see the log in the log view. Is there an option somewhere to have Octane write out and amend the log to a text file on a frame by frame basis? That could really help to track down these errors. I am really dead in the water right now...

You can but will not help to find i suppose. Best to watch vram and triangle counts in LV. Anyway copy this "octane_log_flags.txt" to Cinema4D.exe's place. And run and watch resulting "octane_log.txt".

Thanks, I will do that. Also, what does this mean:
Could not load 'C:\Users\<me>\Dropbox\Cinema 4D Files\<Project>\tex\263742_4d47604d5ca7c830d1fe368209719e62.png:rgba'.
I have no such texture that is in my scene, or that directory (I replaced the items in the <> as they are not relevant information here). Is this a texture that Octane created? Should I be concerned with this at all?
