Pro Tip: your installation of Cinema C4D contains the resource\modules\ folder.

In that folder, you find sub-folders. These sub-folders contain Cinema's resource files. So you actually have hundreds of example files for all of this.

And of course lots of examples on GitHub.

@mikeudin said in Custom FIELDLAYER_CHANNELFLAG:

So instead color, value, direction and rotation flags

These things aren't flags. These properties are hard-coded in the FieldOutput struct.

@SolarPH said in Python NODES - Shouldn't really they can change the scene?:

without any need of any plugin

If you want to have interaction with a scene without plugins you could do this:

• Add a Python Scripting Tag to your scene
• Add user-data buttons and other UI to that tag
• implement the message() function of that tag
• in that message() function, you can react to interaction with the tag's user-data UI
• you can write code that is executed from the main thread to edit the scene safely
• and leave the poor Python Node and all that thread stuff alone...

I don't think you can configure a bitmap button in a res file.

You can add a BITMAPBUTTON parameter in the res file (e.g. ocamera.res). But then you have to implement DescriptionToolData::GetDDescription() to define the specific settings of this parameter's GUI.

IsDirty() is only relevant in the pipeline of an ObjectData generator plugin (BaseObject Manual).

You need C4DAtom.GetDirty() or C4DAtom.GetHDirty() to compare the dirty checksums.

Why are you calling SetDirty() before calling GetDirty() ?

Why not use GetHDirty(c4d.HDIRTYFLAGS_OBJECT_HIERARCHY)? (Dirty States)

@intenditore said in Python tag - IsDirty() not working?:

AttributeError: 'c4d.BaseObject' object has no attribute 'SetDitry'

According to this error message, you wrote SetDitry

And BTW, in your *.h file you miss the comma in line 7 : " = 1001,"

Maybe you have to call LayoutChanged() after that. See gedialog_gadgets.cpp.

You can simply edit the MATERIAL_TRANSPARENCY_COLOR parameter.

Mat[c4d.MATERIAL_TRANSPARENCY_COLOR]

The parameter stores a c4d.Vector.

You find examples on how to handle materials on GitHub.

Example 1 is the initialization of a C-array from a brace-enclosed list.

Example 2 is the construction of a std::vector object using an initializer list.

So, does maxon::BaseArray has initializer list constructors or methods?

Looking at the API, it seems it does not have such a constructor, but methods handling std::initializer_list. So you can actually write:

maxon::BaseArray<maxon::Int> testArray;
testArray.Append({ 1,2,3 }) iferr_return;

Hi,

Cinema has a programmable Token system that can be used to define parts of the final file name

• Variable Path and File Names
• Token System Overview
• c4d.modules.tokensystem

If you are using a BitmapButtonCustomGui, you could simply change the image the bitmap button is displaying. E.g. use an image filled with the background color.

SetFontSize() is a static function. Just consult the documentation before using a function.

It changes the font size of the given font description (in form of a BaseContainer).

You can use that BaseContainer with SetFont(), which also has a font size argument.

You find an example in the GeClipMap Manual.

I'm not an expert on PIL, but it seems to have a getpixel() method. So you should be able to read each pixel value and write it into a BaseBitmap with SetPixel().

Not sure if it helps in your case, but BaseMaterial has a Compare() function.

To change the name of all the scene objects, you have to iterate over all the objects. You can do that recursively or non-recursively.

For the given object, you can simply check if the name has a "." and get the substring before that dot.

# get name
name = op.GetName()

# find last ".""
pos = name.rfind(".")
if pos != -1:
    
    # get substring
    name = name[0:pos]
     
    print(name)
    op.SetName(name)
    c4d.EventAdd()

But this will change the name of all objects that have a "." in the name. A more advanced version of this would check if the part right of "." is actually a number.

I assume that with "geometry" you mean a PolygonObject?

I observed this behavior when not setting up the PolygonObject correctly. E.g. not doing an update after its internal data was changed (points and polygons).

polyObject->Message(MSG_UPDATE);

GeLoadString() is the way to go. You actually find plenty of examples of GeLoadString() being used in the C++ code base (e.g. asynctest.cpp) and this doc: String Manual (Classic).

You can react to the message BFM_GETCURSORINFO. See GUI and Interaction Messages Manual
