Btw. you can do this even easier. There is the GeChooseColor() function which opens the color picker and returns the picked color as parameter.

The picked color is passed to the 'color' parameter.

matthias,

having issues linking color picker parameters to materials created using insertmaterial.

doc->InsertMaterial(mat, NULL, FALSE);
// apply color from colorpicker to newly formed material
mat->SetChannelState(CHANNEL_COLOR(IDC_MODUS), TRUE);

IDC_MODUS refers to the native colorpicker that was evoked by AddColorChooser. I know that the above is incorrect. how do i get the color/brightness selected from the colorchooser to affect the parameters of the inserted material?

Get the 'color' using GeChooseColor and then set the material parameter:

// Enable Color Channel in Material
mat->SetChannelState(CHANNEL_COLOR, TRUE);
// Set Color to 'color'
mat->SetParameter(DescID(MATERIAL_COLOR_COLOR), GeData(color), DESCFLAGS_DONTCHECKMINMAX);

I've been working with GeChooseColor and it is not as convenient as I would hope for. At least, I am not certain how I can "dock" it permanently into my plugin dialog. Right now it shows up as a "pop-up".

I am also curious as to why I couldn't use the AddColorChooser attributes to affect materials created. Is there a way to pass the color and brightness of the AddColorChooser to materials created.

Believe me, i have been trying various ways to get this to work and I have not found anything definitive in the SDK.

Maybe tell us something about what you are trying to achieve. GeChooseColor() is just a color picker dialog popup. AddColorChooser() is just the standard Cinema color dialog element.

matthias,

one portion of the plug i'm working on is the ability to utilize the native c4d color-picker to create any objects and materials with the chosen color AND brightness control. it would also be nice to have the color-picker as a permanent feature of the dialog. surely there is an accessible way to use the standard color picker to affect materials/objects to be created.

Just to make sure we are talking about the same thing. This is an example plugin dialog with AddColorChooser(). Of course the look depends on Cinema's color chooser preferences.

matthias,

that's just insane! now i feel guilty and humbled by your knowledge- thanks!

i also take from this that there is no, unfortunately, convenient way to access the features of the native color picker in c4d...too bad.

ah, so this is from one of the examples in the sdk...
