Example Code

The following code does not use the correct values when setting the data. You should check directly in C4D for the correct values that you should use in place of the ones that are shown. This code is just to show you how to access the values for getting and setting the parameters.

Python

import c4d
from c4d import gui
def main():
    material = c4d.BaseMaterial(c4d.Mterrain)
    
    #You can set parameters two different ways. 
    #First way              
    material[c4d.MATERIAL_PAGE_PROPERTIES] = True
    material[c4d.TERRAINSHADER_TYPE] = c4d.TERRAINSHADER_TYPE_CUSTOM
    material[c4d.TERRAINSHADER_HEIGHT] = 0.1
    
    #Second way, using the base container.
    bc = material.GetDataInstance()
    bc.SetBool(c4d.MATERIAL_PAGE_PROPERTIES,True)
    bc.SetInt32(c4d.TERRAINSHADER_TYPE,c4d.TERRAINSHADER_TYPE_CUSTOM)
    bc.SetFloat(c4d.TERRAINSHADER_HEIGHT,0.1)

if __name__=='__main__':
    main()
             

C++

#include "c4d.h"
#include "../shader/description/mterrain.h"
void SampleFunction()
{
    BaseDocument *pDoc = GetActiveDocument();
    BaseMaterial *pMaterial = BaseMaterial::Alloc(Mterrain);  
    
    //You can set parameters two different ways. 

    //First way              
    //Some objects do not store all their data in the container. You need to use GetParameter()/SetParameter() instead. 

    DESCFLAGS_SET flags = DESCFLAGS_SET_PARAM_SET;
    pMaterial->SetParameter(DescID(MATERIAL_PAGE_PROPERTIES),GeData(true),flags);
    pMaterial->SetParameter(DescID(TERRAINSHADER_TYPE),GeData(TERRAINSHADER_TYPE_CUSTOM),flags);
    pMaterial->SetParameter(DescID(TERRAINSHADER_HEIGHT),GeData(0.1),flags);
    pMaterial->Message(MSG_UPDATE);            

    //Second way, using the base container.
    BaseContainer *bc =     pMaterial->GetDataInstance();
    bc->SetBool(MATERIAL_PAGE_PROPERTIES,true);
    bc->SetInt32(TERRAINSHADER_TYPE,TERRAINSHADER_TYPE_CUSTOM);
    bc->SetFloat(TERRAINSHADER_HEIGHT,0.1);
    pMaterial->Message(MSG_UPDATE);                                                      
}
             

Gradients

This node has gradients. Gradients can manually be edited by calling the following code

Python

C++

           
#include "customgui_gradient.h"
TERRAINSHADER_COLOR
                                
GeData data;
pMaterial->GetParameter(DescID(TERRAINSHADER_COLOR),data,DESCFLAGS_GET_PARAM_GET));
Gradient *pGradient = (Gradient*)data.GetCustomDataType(CUSTOMDATATYPE_GRADIENT);
if(pGradient)
{    
    //must be set before any knot is set
    pGradient->SetData(GRADIENT_MODE, GeData(GRADIENTMODE_ALPHA));
    GradientKnot k1, k2;
    k1.col = Vector(0.0, 0.0, 1.0);
    k1.pos = 0.0;
    k2.col = 1.0;
    k2.pos = 1.0;
    pGradient->InsertKnot(k1);
    pGradient->InsertKnot(k2);
}
pMaterial->SetParameter(DescID(TERRAINSHADER_COLOR),data,DESCFLAGS_SET_PARAM_SET));
