Thanks for the reply.
I've been trying to use the Get/SetParameter() method. like this:
shd->SetParameter(DescID(NOISESHADER_SCALEX), GeData(2.0), DESCFLAGS_SET_0);I wasn't even sure if using this was the right method to get at the data. So thanks for confirming that for me.
But NOISESHADER_SCALEX produces an undefined error.
I must be missing something really simple.-ScottA

You will probably need to include the header from the resource/modules/shader/res/description folder.

Once again..You saved my butt Robert.
I got the ID: NOISESHADER_SCALEX by dragging from the dialog into the console.
But I could not find any reference to this ID anywhere in my file structure.
I have been using the built-in Windows Vista search option. And it usually finds things like this for me very well. But in this case it failed me.Do you have a favorite program, or method, you use search through all of the files for specific ID's?
It looks like I can't trust the Windows search anymore.-ScottA

I use something called Agent Ransack. It works brilliantly!

I'll check it out.
But..I'm stuck again. (Don't kill me. I'm trying hard
).Now I need to know how to change the gradient knots.
All I can find is examples on creating brand new gradients from scratch using the gradient class.
But what I need to know is just how to change the .pos values and the Vector() values of the two existing knots.I'll post the complete code when I'm done. So anyone else new to this stuff doesn't have to ask you guys these same simple questions over again.

I couldn't figure out how to edit existing gradients. So I tried allocating a new one. And it seems to replace the old one. So I guess that will work. *shrug*
Here's the entire plugin code:

The mode option is still broken. But I'm exhausted from starring at this thing. So I'm taking a break.Thanks for the help guys,

There is no need to allocate a Gradient if you just want to change it in an existing shader.
Here is a simple example. It sets the knot's postion to a random value.
GeData d; // get the data if (shd->GetParameter(DescLevel(SLA_GRADIENT_GRADIENT), d, DESCFLAGS_GET_0)) { //get the Gradient custom data Gradient *gd = (Gradient* )d.GetCustomDataType(CUSTOMDATATYPE_GRADIENT); if (gd) { // iterate through all knots and set them randomly LONG kcnt = gd->GetKnotCount(); Random rnd; rnd.Init(436357); for (LONG i=0; i<kcnt; i++) { GradientKnot knot = gd->GetKnot(i); knot.pos = rnd.Get01(); gd->SetKnot(i, knot); } // set the gradient shd->SetParameter(DescLevel(SLA_GRADIENT_GRADIENT), d, DESCFLAGS_SET_0); shd->Message(MSG_UPDATE); EventAdd(); } }Also check the GradientShader.cpp SDK example for some more sample code.

Still doesn't work for me.
It looks like the problem begins when trying to get the gradient's container:Bool SimplePlugin::Execute(BaseDocument *doc) { BaseMaterial *mat = doc->GetFirstMaterial(); // Get the first material and assign a variable to it if(!mat) return TRUE; // Error handling BaseContainer *data = mat->GetDataInstance(); // Get the material's container BaseShader *shd = BaseShader::Alloc(Xsimplenoise); data->SetLink(MATERIAL_COLOR_SHADER, shd); // Adds a SimpleNoise shader to the color channel in memory only mat->InsertShader(shd, NULL); // Adds the Simple Noise to the color channel from memory mat->Message(MSG_UPDATE); // update the changes mat->Update(TRUE, TRUE); // updates the material icon EventAdd(); ////////////////// EVERYTHING IS WORKING AT THIS POINT ///////////////////////////////////// //Now lets try to access the gradient and it's parameters GeData d; if (shd->GetParameter(DescLevel(SLA_GRADIENT_GRADIENT), d, DESCFLAGS_GET_0)) { GePrint("Is this working so far?"); //<-----Yes. This does print and proves that everything is working at this point Gradient *gd = (Gradient* )d.GetCustomDataType(CUSTOMDATATYPE_GRADIENT); //get the gradient's custom data if (gd) GePrint("true"); else GePrint ("false"); // <-------Prints false. The code is broken. Starting from Gradient *gd // We are not properly accessing the gradients container. We cannot continue until this is fixed }I'm sure I'm missing something really simple.

SLA_GRADIENT_GRADIENT is the wrong ID for the gradient of the Simple Noise shader. Please use NOISESHADER_COLOR instead.
