Hello everyone.
I am new to C4D scripts.
I may have posted this message in the wrong section of this forum, please let me know if that happened.
I want to create a script to get a material with certain properties and assign it to an object selected in the scene.
For the Brightness and Displacement channels, images from the disk are added.

import c4d
from c4d import storage
def main():
# doc = c4d.documents.BaseDocument
# Step 1: Create a new material
material = c4d.BaseMaterial(c4d.Mmaterial) # Creating new material
material.SetName("MyMat") # Assigning a name to a material
doc.InsertMaterial(material) # type: ignore # Adding material to a document
# Step 2: Disable the Color Channel
material[c4d.MATERIAL_USE_COLOR] = False
# Step 3: Disable the Reflectivity channel
material[c4d.MATERIAL_USE_REFLECTION] = False
#Step 4: Enable the Brightness channel
material[c4d.MATERIAL_USE_LUMINANCE] = True
# Step 5: Select a texture file for the Brightness channel
luminance_texture_path = storage.LoadDialog(type=c4d.FILESELECTTYPE_IMAGES, title="Select a texture for the Brightness channel")
if luminance_texture_path: # Checking if the user has selected a file
luminance_shader = c4d.BaseShader(c4d.Xbitmap) # Create a shader for the image
luminance_shader[c4d.BITMAPSHADER_FILENAME] = luminance_texture_path # Assigning a path to a file
material[c4d.MATERIAL_LUMINANCE_SHADER] = luminance_shader # Assigning a shader to a material
# Step 6: Enable the DISPLACEMENTt channel
material[c4d.MATERIAL_USE_DISPLACEMENT] = True
# Step 7: Select a texture file for the Displacement channel
displacement_texture_path = storage.LoadDialog(type=c4d.FILESELECTTYPE_IMAGES, title="Select a texture for the Displacement channel")
if displacement_texture_path: # Checking if the user has selected a file
displacement_shader = c4d.BaseShader(c4d.Xbitmap) # Create a shader for the image
displacement_shader[c4d.BITMAPSHADER_FILENAME] = displacement_texture_path # Присваиваем путь к файлу
material[c4d.MATERIAL_DISPLACEMENT_SHADER] = displacement_shader # Assigning a path to a file
# Updating the material to apply the changes
material.Update(True, True)
# Step 8: Assign material to selected objects
selected_objects = doc.GetActiveObjects(c4d.GETACTIVEOBJECTFLAGS_0) # type: ignore # Get a list of selected objects
if selected_objects: # Checking if objects are selected
for obj in selected_objects:
texture_tag = c4d.TextureTag() # Create a new texture tag
texture_tag.SetMaterial(material) # Assigning the material to the tag
obj.InsertTag(texture_tag) # Add a tag to the object
# Updating the scene
c4d.EventAdd()
# Script running
if __name__ == '__main__':
main()
Why are the selected images for the material shaders not assigned to the specified shader?
