Just FYI: you find that information regarding ./res/libs/win64 in the documentation: Development for Microsoft Window

Hello,

as Riccardo has pointed out, AdditionalIncludeDirectories has nothing to do with DLLs. It is used to define search paths for header files. See Additional include directories. It was never valid.

Also, looking at the error, the plugin was installed into the C:/Program Files folder. In R21, there is no reason to install plugins there; one can install plugins at any location and just tell Cinema 4D the plugin path.

best wishes,
Sebastian

Hello,

this particular preferences plugin only loads its data when needed. To trigger that, you can call GetDescription() which will internally load the data.

plugin.GetDescription(c4d.DESCFLAGS_DESC_0)

# Get existing paths
dbPaths = plugin[c4d.PREF_DATABASE_PATHS]

best wishes,
Sebastian

Hello,

these paths are accessed with a preference plugin. You can access that plugin:

plugin = c4d.plugins.FindPlugin(1040566)

paths = plugin[c4d.PREF_DATABASE_PATHS]

# print paths
print(paths)

# add a path
paths = paths + "\n" + "X:\someting" 
plugin[c4d.PREF_DATABASE_PATHS] = paths

c4d.EventAdd()

best wishes,
Sebastian

Hi,

I think you you mean the gadget under the mouse, do you?

Hello,

the edit mode is stored with the current BaseDocument and accessed with GetMode(). See also IsEditMode().

if doc.GetMode() != c4d.Mmodel:
    return

My thoughts on this: as always, this is a question on software design and the correct level of abstraction. The question is not how do different plugins communicate with each other, but how do different parts of a software communicate with each other. And how is software structured to make that communication efficient and clear.

The typical modern approaches are patterns like Model-View-Controller or Model-View-Presenter.

In such models, you don't "send data around". Your UI updates the model. And an update of the model triggers an update or (other parts of the) UI.

So in your example, the interaction with the DescriptionToolData would write data into the model. And the GeUserArea would read that data from the model. The only question is how you trigger that update process; and that depends on what exactly you are doing in what cases Cinema allows to update the UI.

Hello,

just FYI: GetDocPreviewBitmap() returns the image that is stored in the c4d file and that is used as a thumbnail image. It is created when the scene is saved; it has nothing to do with the current viewport image.

Well, what error does GetGeneralLicensingInformation() return? You can check the error message: Error Class

Hello,

please have a look at the definition of the ModifyObject() method.

The first argument is the modifier object itself. The third argument is the object to modify.

For some reasons, you changed the names of the input parameters. But in C++, that won't matter. Only the type and the order of arguments is relevant.

So assuming that SSURFACEDEFORMERC_DRIVER is a parameter of the modifier object, you must access that modifier object. An in the context of ModifyObject(), that would be the first parameter.

best wishes,
Sebastian
