Create NFT 3D Collectibles Using Blender Scripting

hideckies on November 21, 2021

I wanted to create 3D characters for about 1000+ NFT Collectibles, but didn't know how to do that. It's stupid to create all models one by one manu...

Hello, can I edit and make use of your NFT example as the base model for my own NFT collection?

Hello. Sure, feel free to use it.

Hi there! Thank you so much for the script, it's seems great!
However, I don't know how to use it. -_-"
I tried using this with the files you provided but I keep getting snagged at the duplicate error. I don't understand what I should be doing to go past that. :(
What duplicates is it talking about?

Hi, thanks!

As I said here, please set TOTAL_CHARACTERS = 2. I think it will probably work. Anyway, repeat "Run" until you succeed.

This error occurs when the combination of parts is duplicated.
Our ideal is to create a unique collection, so we have to avoid the exact same characters.

Hi,

How do I make it so that it uses the second character only if a t-shirt is selected to be displayed?

Such a case, you can add the optional code after random.choice() in gen_metadata.py

def rand_attributes(id):
    # ...
    random_model = random.choice(...
    random_clothes = random.choice(...

    # Add it!
    if random_clothes == "t-shirts":
        random_model = "another"    # assumed that the model names are "original" and "another"

    # ...
    random_model = random_model.replace(...
    random_clothes = random_clothes.replace(...

    attributes = [...]

Hi hideckies I'm using your code (thanks btw). I made some NFTS to test and I notice that the PNG number differs from the JSON file number after 3 renders. Is that a reason for that? Thank you for you time.

Hey, amazing information here, thanks a lot! Is It possible to create that kind of script in cinema4d?

hideckies • Nov 28 '21

Thank you! But sorry, I don't know about Cinema4D.

hello, thank you it was really very useful
I have a question
I only have 1 model, 1 head
to this I want to apply different textures and backgrounds
in order to release various versions

is it possible to do this with this script?

In that case, add multiple materials(textures) to the object (e.g. material names are "material_1", "material_2", so on) in advance, then you can write for example:

# gen_metadata.py

# List
list_background = [black, red, green, ...]
list_head = [material_1, material_2, ...]

random_background = random.choice(list_background)
# ...

attributes = [
    {
        "trait_type": "Background",
        "value": random_background
    },
    # ...
]

# gen_model.py

# Assign background material
def assign_background_material(material_name):
    # Get the object named "background" in the "misc" collection from the scene
    background_object = bpy.data.objects["background"]

    # Set the material you want to assign
    target_material = bpy.data.materials.get(material_name)

    # Assign material
    background_object.data.materials[0] = target_material

# Append head
def append_head(trait_value):
    # Set the material name (e.g. "material_1", "material_2", etc)
    material_name = trait_value

    # Append "head" collection in the scene
    path = PARTS_DIR + "head/head.blend/Collection/"
    bpy.ops.wm.append(filename="head", directory=path)

    # Get the "head" collection
    head_col = bpy.data.collections["head"]

     # Assign material
    target_material = bpy.data.materials.get(material_name)
    for head in head_col.objects:
        head.data.materials[0] = target_material

# Generate
def generate(id, metadata):
    # Background
   if attr in metadata["attributes"]:
        if attr["trait_type"] == "Background" and attr["value"] != "":
            assign_background_material(attr["value"])
    # ....

how do I run this on a render farm, should I code it so that it makes 4444 .blend files?
I would appreciate it if you could include the code in the comments :))
