I will try to explain all the steps I'm doing.

I have an ObjectData plugin, with the .pyp extension that is working.
I dissected the RoundedTube file from the SDK and made my plugin from it (with a unique ID, of course).

I tried compiling it from the Terminal (I'm on a Mac) with:

cd /Applications/MAXON/CINEMA\ 4D\ R13/resource/modules/python/res/Python.osx.framework

python -m compileall /Applications/MAXON/CINEMA\ 4D\ R13/plugins/Actor

...and I get:

Listing /Applications/MAXON/CINEMA 4D R13/plugins/Actor ...
Listing /Applications/MAXON/CINEMA 4D R13/plugins/Actor/res ...
Listing /Applications/MAXON/CINEMA 4D R13/plugins/Actor/res/description ...
Listing /Applications/MAXON/CINEMA 4D R13/plugins/Actor/res/strings_us ...
Listing /Applications/MAXON/CINEMA 4D R13/plugins/Actor/res/strings_us/description ...

But no Actor.pyc file is produced.
If I change the extension of the original plugin to .py and perform the same steps to compile it, I do get a .pyc file.
But using that .pyc file doesn't load the plugin.
So, how can I compile a python plugin properly?

The

.pyp

extension is Py4D specific. To protect Py thon P lugins, you habe to use the Source Protector plugin from the Python Plugins Menu (R12) or the Scripting Menu (R13).

.py | .pyw | .pyc | .pyo

files are simply Python source/nowindow/compiled/object files and Py4D doesn't assume they're plugin-files.

Thank you for the reply, Nik

So, there isn't any way to compile my .pyp files?
Is there even any advantage of compiling python files?

Well, I'd say to protect your source?
You can both, protect your .pyp and your .py files. (You can outsource your code to .py files and compile those to .pyc)

I was asking this because "protecting" is not the same as compiling.
Usually, compiling speeds things up.
Does this means that compiling (not protecting) has no advantage whatsoever?

I think the .pyc files are faster to load yes.

so protect the .pyp file using the source protector in c4d, then compile all your .py files

you can get rid of the .py files once compiled, just leave the .pyc in there

Well, I didn't know that this was your point. Actually the only thing that speeds up is loading, as mchaloner already said.
I don't know about the implementation details of the "protected" .pyp files (.pype) but I'm pretty sure they're not just obfuscated but compiled.

really if you're using .py packages your .pyp should be pretty small in terms of code, so the protected .pype should run pretty quick!

@mchaloner: I don't think "run pretty quick" is the correct term, here. The code doesn't run faster because the code-size is small. It just loads faster, and loading is done at Cinema 4D startup.
Also, outsourcing of code should be done in a "senseful way". Don't seperate each function to another source file. Importing does take it's take, too (when you want to decrease loading time).

When you know where your source-files are (and you usually do, because they're in your plugin folder), instead of appending the path of the plugin's directory, rather insert it at the beginning of the sys.path list.
In the former case, the Python Interpreter would walk through each folder in sys.path and finally gets to your plugin's path after it has traversed a number of other directories. In the latter, it will find your module at the first path in sys.path.

no, I was just saying that if you are using .py packages - your .pye wouldn't have much code in it, therefore Cinema 4D's loading of that plugin should be faster.

Nope. It just speeds up the start-up of cinema 4d. If that is even noticeable..
