Hi Andreas

It is an external application, and therefore does not require the ownership of Cinema4D. It's not a plugin. Which means, no connection to C4D.
This application also imports OBJ, FBX, 3DS...etc formats and it is not necessary to have the original applications of these formats!
The SDK therefore does not seem to allow a total independent import of .c4d scenes.
There will therefore be no Cinema4D import/export.

Unless I can get the description on the structure of a .c4d file. In this case, I would write my own import/export library ;)
Of course, the information received will remain confidential.

Sorry but I remain convinced that there is, somewhere in the scene file, an information that allows you to reconstruct a parametric sphere!
Without this information, how does Cinema4D rebuild the sphere? With a session of spiritualism?
A normal user will not always think to activate the options of the Mix SDK.
I think I'll drop the c4d scene import.

Hi Andreas

Okay, thank you for these explanations ;)

At the moment, the only solution is to limit the import to polygonal objects and exclude all parametrics objects.
I hope that Melange will evolve to allow a total import of a c4d scene. This caching principle is not really practical:(

But how does Cinema4D know the size of a parametric sphere when loading a scene?
There's got to be a way to find that information somewhere, no?

Otherwise, can I get from Maxon, the specifications of the .c4d file format?

Unfortunately, that's what I thought :(
So I'll have to write a MakeEditable function ;)

Thanks Ricardo

For a polygonal object, I have no problem calculating the BBox.
My question concerns PARAMETRIC objects, which do not have points.
The information must exist in the.c4d file. Otherwise, how would Cinema4D find the size of a sphere or other parametric object?

So, unless I get a description of the structure of a.c4d file, I must be able to find the size somewhere!

How to get the size of a parametric object? As with BaseObject::GetRad()

Hi

The documentation of Melange is not very clear, and there is only one example :(

Can we convert a parametric object into a polygonal object, as we do with "makeeditable" in a plugin?

Thanks Andreas ;)

ViewportSelect.PickObject(), this is what I use to select an object in the 3D View.

What I'm trying to do seems complex and unreliable.
I'll try to find another solution.
As I said, when the scene is complex, it is difficult to reach a particular object, especially if it is small.
