Hi @sortsovs once you have the node, you need to retrieve the appropriate port. Be careful as some port can be nested. Then once you have the correct port, you need to call GraphNode.SetDefaultValue. When calling SetDefaultValue it is important to pass a maxon data as the current Python system is not able to automatically guess the expected result. Find bellow an example to create a Redshift Material with a Texture Node with a custom path and name. import c4d import maxon REDSHIFT_NODESPACE_ID = maxon.Id("com.redshift3d.redshift4c4d.class.nodespace") def CreateTextureNode(gr: maxon.GraphModelRef, nodeName: str, texturePath: str, isLinear:bool=False) -> maxon.GraphNode: # Start a transaction to inform the graph that a modification is going to happen with gr.BeginTransaction() as transaction: # Create a Redshift Texture Node and rename it textureNodeId = maxon.Id("com.redshift3d.redshift4c4d.nodes.core.texturesampler") texNode = gr.AddChild("", textureNodeId, maxon.DataDictionary()) texNode.SetValue("net.maxon.node.base.name", maxon.String(nodeName)) # Retrieve path and gammage override port path = texNode.GetInputs().FindChild("com.redshift3d.redshift4c4d.nodes.core.texturesampler.tex0").FindChild("path") gammaOverride = texNode.GetInputs().FindChild("com.redshift3d.redshift4c4d.nodes.core.texturesampler.tex0_gammaoverride") # Define the value stored by the node for these port when no connection exist gammaOverride.SetDefaultValue(maxon.Bool(isLinear)) path.SetDefaultValue(maxon.Url(texturePath)) # Push the change to the graph transaction.Commit() return texNode def main() -> None: # Create a BaseMaterial in the active document rsMat = c4d.BaseMaterial(c4d.Mmaterial) doc.InsertMaterial(rsMat) # Retrieve it node material part and create a Redshift Graph nMat = rsMat.GetNodeMaterialReference() nMat.AddGraph(REDSHIFT_NODESPACE_ID) gr = nMat.GetGraph(REDSHIFT_NODESPACE_ID) # Create a texture node albedoTexNode = CreateTextureNode(gr, "Albedo", r"C:/PathToATexture.jpg") c4d.EventAdd() if __name__ == '__main__': main() Cheers, Maxime.
