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

Hello,

just FYI: you find information on how to access individual characters from a string in the manual: String Manual

Also, one of our examples includes checking the ASCII value of a given character: streamconversion_impl.cpp

If your question has been answered, please mark your thread as a question and set it to "solved".

best wishes,

Yes, using GeUserArea is a way of creating a custom node editor (or any kind of custom UI).

Please make sure you understand the difference between a data type and a GUI. A data type stores data of some type. A GUI displays that data and allows interaction with that data in the UI. But it does not persistently store the data.

So if you want to have a parameter in your object that stores a float value, just use a REAL parameter. You can display that parameter in the UI using a custom GUI element. See for example customgui_string.cpp.

Sorry, but this is not how it works. A NodeData's res file looks like this:

STRING ID_RESULT_TEXT  { CUSTOMGUI MULTISTRING; ANIM OFF; }

The first symbol is the data type (STRING), the second the parameter ID, The custom GUI can be found after the CUSTOMGUI keyword.

So in your case, MY_CUSTOMGUI is NOT a custom GUI. It is a custom data type. Is that correct?

Hello,

you can implement a custom class based on GeUserArea. In such custom gadget, you can control everything: what is drawn, how it is drawn and how the user interaction works. The problem is that you have implement all of that yourself. So depending on the complexity of your desired solution, this can be a lot of work.

See this previous discussion: Node Graph

In an ObjectData plugin, you don't access GUIs. You access parameters. So what is the parameter type that is using your custom GUI? Can you show your *.res file?

How the Xpresso Node UI is added to a GeDialog is shown here: gedialog_gadgets.cpp

However, since GvGetWorld() and related functions are not available in Python, I guess it is not possible to use the Xpresso UI in a Python based GeDialog.

"Blur Offset" and "Blur Scale" are parameters of the BaseShader class, so you should be able to access these parameters like any other parameter; if in doubt, they should be available in the shader's BaseContainer. See xbase.h.

Hello,

as always, please make yourself familiar with how to post questions on this forum: Read Before Posting

I assume a "template file" is just a C4D-file that stores some materials?

You can load a C4D-File with LoadDocument(). Then you can copy the materials found in that loaded document into the active document. See BaseDocument Manual and BaseMaterial Manual.

import c4d
import os

def main():
    # select the c4d file to load
    filename = c4d.storage.LoadDialog(type=c4d.FILESELECTTYPE_SCENES, title="Choose File.", flags=c4d.FILESELECT_LOAD, force_suffix="c4d")
    if filename is None:
        return

    # checks for c4d suffix
    name, suffix = os.path.splitext(filename)
    if suffix != ".c4d":
        raise RuntimeError('Invalid file selected.')

    # load the document (materials)
    loadedDoc = c4d.documents.LoadDocument(filename, c4d.SCENEFILTER_MATERIALS)
    if loadedDoc is None:
        raise RuntimeError('Could not load document.')
    
    # get all materials
    
    mat = loadedDoc.GetFirstMaterial()
    
    while mat is not None:
        
        # clone material
        clone = mat.GetClone()
        if clone is None:
            raise RuntimeError('Could not clone material.')
        
        # insert clone into the active document
        doc.InsertMaterial(clone)
        
        mat = mat.GetNext()
        
    c4d.EventAdd()

if __name__=='__main__':
    main()
