These are some useful workflow scripts for Cinema 4D’s graph view. Scripts are written for Maxon Cinema 4D R21.026 and they work with Xpresso and Redshift node graph (except specific ones).

Node Tools scripts:

AR_AddRSTextureControllers
Creates individual scale, offset and rotate control nodes for Redshift texture and triplanar nodes. If you select multiple texture nodes the script creates shared controllers.

AR_AlignNodesHorizontally
Aligns selected graph nodes horizontally.
SHIFT-key: align nodes to center.
CTRL-key: align nodes to right.

AR_AlignNodesVertically
Same thing as the previous script but this one aligns graph nodes vertically.
Key modifiers works with same way with this script.

AR_ConnectNodes
Connects two selected nodes, if possible. Connects first open port to first open port.
SHIFT-key: User input output port to input port (index starts from 0 zero).
CTRL-key: Connects last open port to last open port.

AR_DistributeNodesHorizontally
Distributes selected graph nodes horizontally between the first and the last node.
The first node and the last node are picked by the minimum and the maximum x-position values.

AR_DistributeNodesHorizontally
Same thing as the previous script but this script distributes graph nodes vertically.
The first and the last node are picked by the minumum and the maximum y-position values.

AR_LineUpNodesHorizontally
Lines up selected graph nodes horizontally.
SHIFT-key: set custom gap size (default gap size is 20).

AR_LineUpNodesVertically
Same thing as the previous script, but this lines up selected graph nodes vartically.

Place script files to your library folder:
C:\Users\[USERNAME]\AppData\Roaming\MAXON\Maxon Cinema 4D R[VERSION]\library\scripts

N.B. Xpresso tag / Redshift material has to be selected when you run the script. Also make sure that you don’t have unnecessary active selections.

This is small and simple Python Effector that delays clone’s color. Effector takes clone’s incoming color value and mixes it with clone’s previous color by the amount of delay variable in percentages. Therefore you have to use quite high delay value to get visible effect.

It was a good time to update my personal computer build since the previous setup is about seven years old. I also did my very first custom loop watercooling. It was super fun, exciting and a bit nervous project. Bending tubes was a bit tricky. However, no leaks or anything. Perfect!

I build my new computer earlier this year using Noctua NH-U14S CPU-cooler and last weekend completed my setup installing custom loop system. The computer is now much quieter and a quite bit cooler. I might later add s second GPU and same time I could improve my wonky tubing. I haven’t overclocked my rig yet, but soon I will. However, I wanna keep my rig really stable.

This is a Python Tag script that uses a basic Null object to make a nice object manager separator. Change separator’s name in Null object’s User Data and select style and width as you wish.

The script is created to work with Cinema 4D’s default UI font: Segoe UI, Regular 11. Since the font is not a monospace typeface, I had to go through each letter, number and symbol and gave them a custom weight. Weighting is not perfect but it is better than nothing.

N.B. supported characters are very limited.

Here is two Python Tags that toggles object’s visibility by given frames.

Toggle Visibility

This Python Tag toggles it’s object’s visibility. You can input individual frame numbers or frame ranges. Use a comma to separate different selections. Frame numbers that you put in to the input field are “selected frames”. You can change operation what happens to selected frames or non-selected frames.

toggle_visibility_python_tag.c4d

Toggle Visibility Controller

This one works like the previous one but instead controlling only one object, you can control multiple objects’ visibility. Add more items with “Add” button. You can add as many item as you want. “Remove” button removes always the last “Toggle Visibility” group.

This is an old script that I made, but I wanted to wrote something about it before I forget everything. The script exports selected layers masks from Adobe After Effects to text file that you can copy paste straight to Black Magic Fusion composition. The script exports only the paths, it does not support feather, opacity, expansion or other fancy things.

I created this script because sometimes I have to rotoscope something and when that happens I only use free version of Mocha that comes bundled with After Effects. But since I have started to use Fusion more and more I had to figure a way to get my rotoscoped Mocha shapes to Fusion. Fusion’s own rotoscope tools are fine, but I’m so much faster with Mocha.

After Effects and Fusion have a different coordinate systems.

Following pseudocode shows how mask vertices are remapped from another coordinate system to another:

 // lerp(value, old min, old max, new min, new max)
x = lerp(vertices[n].x, 0, compositionWidth, -0.5, 0.5)
y = lerp(vertices[n].y, 0, compositionHeight, 0.5, -0.5)

Tangents are remapped similarly, but by trial and error I found out that I need to additionally add 0.5 to X-tangents and subtract 0.5 from Y-tangents to get right result.

This was a really quick JavaScript project that I made when I was a bit bored. I wrote it originally with Python, but I wanted to port it to JavaScript, so it is easy to use in browser or something.

It is render time estimator. Just type frames or frame range and average time how much it takes to render a single frame and then render time estimator calculates how long it takes to render whole sequence.

Time should be given in HH:mm:ss format.

This is my first Python Field Object. With Selector Field, you can easily select items by typing their ID’s (e.g. 0, 10, 11, 25, 30 and so on). Selector Field supports also range selections which works by typing start ID and end ID e.g. 5-20, 49-99, 0-3 and so on.

Originally Selector Field is intended to use with MoGraph Effectors but it works also with polygon, edge and point selections and vertex maps.

There is three different ‘Input type’ systems: Single-Line, Multi-Line and Range Sliders. First two allows you to type ID’s and the last one allows you to select items with two sliders.

If you want to invert the selection, go to ‘Remapping’ tab and tick ‘Invert’ checkbox there.

Selector Field won’t update user interface if it does not have anything to process! You should first attach it to somewhere and then modify settings.

N.B. Unfortunately, supported element count is only 400, after that selection will be repeated. Reason for this is that fields uses a new block system and I haven’t got into it yet. Someday I might tackle this new system and update a new version that supports more elements.

Lately I have worked a lot with alembic files that have point level animated geometry and once I had to attach objects to that PLA geometry. I figured out a couple different ways to do this (e.g. MoGraph Cloner or Contraint Tag) but my favorite solution is to use Xpresso and Python.

In this setup I’m taking three points from selected polygon. Then I’m creating vectors v1 and v2 from those points’ positions. Then vectors are used to generate orthogonal axes by using cross product.

import c4d
import math

def main():
    global Matrix

    v1 = Point1 - Point0
    v2 = Point2 - Point0

    m = c4d.Matrix()
    m.v1 = v1.GetNormalized()
    m.v3 = v1.Cross(v2).GetNormalized()
    m.v2 = m.v3.Cross(v1).GetNormalized()
    m.off = Position

    Matrix = m

This was a funny experiment. Sending MoGraph data from Cinema 4D to Novation Launchpad (the first version). I used Python Effector to send UDP packets to Processing and in Processing I used UDP library to read those packets and The MidiBus library to send MIDI messages to Launchpad.

Pads’ indexes starts from 0 and ends to 199. Every circle pad takes 8 indexes so in every row we add that amount to index value. Velocity value changes color and brightness of the pad but I did not have interest to find out what every single values from 0 to 127 did. In my setup I just mapped clone’s red color value (float 0.0-1.0) to MIDI velocity (integer 0-127). Mapping is done in Processing sketch.

Python Effector from this experiment can now be used as a template for different setups to send MoGraph data to other softwares. Data is transfered with UDP packets in strings. So Cinema 4D is sending constantly long strings and Processing sketch is listening those and unpacking those strings to something useful.

Python Effector code

import c4d
import socket
from c4d.modules import mograph as mo

def initSocket():
    global s
    global server
    host = '127.0.0.1' # Host address
    port = 5001 # Port
    server = ('127.0.0.1', 5006) # Server address and server port
    s = socket.socket(socket.AF_INET, socket.SOCK_DGRAM) # Initialize socket
    s.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEADDR, 1) # Re-use socket
    s.bind((host, port)) # Bind
    return s, server

initSocket() # Create a socket

def main():
    md = mo.GeGetMoData(op) # Get MoData
    if md is None: return False # If no MoData return false
    cnt = md.GetCount() # Get clone count
    carr = md.GetArray(c4d.MODATA_COLOR) # Get color array
    message = "" # Initialize message string
    row = 0 # Initialize row integer
    for i in xrange(0, cnt): # Loop through clones
        if i != 0: # If not the first index
            if i % 8 == 0:
                row = row + 8 # Launchpad pad numbering
        color = carr[i] # Get clone's color
        index = (i+row) # Calculate pitch
        message += str(index) + "-" + str(color.x) + "," # Write message
    s.sendto(message, server) # Send message
    return True # Everything is fine
