Applying Materials to Nulls OK in Octane?

[jayroth]

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.

Thanks, Aoktar. What does this error mean?

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".

[jayroth]

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?
