  1. Update: As I was working with the Python console, I discovered that because the script is creating the variable message as a tuple, it was hitting the upper limits of the tuple object's memory. It also dramatically slowed Cinema4D down because tuples are immutables, so it was creating a new instance of the tuple over and over and over again in the for loop. I am working on a script that sends the integer data in "packets" of 512 channels (which will save you processing on the TouchDesigner side, since you are getting the universe data straight from Cinema), so the full size implementation of this idea for 1000+ pixels isn't done yet, but at least I know why it was happening.
  2. Hello! I am working on a pre-viz project for a piece of public art involving a DMX driven LED element. Ideally, I would use a plugin that turns Mograph color data into DMX (ArtNet, OSC, sACN, whatever you got) from Cinema4D, but it could be more generic output that I can then use for my DMX. It is essentially a live link but with DMX over EtherNet outputs (similar to something that Capture promises: https://www.capture.se/). I have not found that plugin and the promising ones are languishing in development to make the transition to macOS 10.15 (Catalina) and R21. So for now, I am using the Python effector to output Mograph color information over UDP, like this: We started with Ken Komuro's video and Alexander Gluschenko's tutorial on how to accomplish it: The code snippet I am using for the Python Effector comes from here: https://aturtur.com/mograph-to-launchpad/ 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 # 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 I have gotten this to work, or at least gotten the UDP data to output (we don't need to worry about the TouchDesigner part). However, the UDP information only shows up in TouchDesigner up to a cloner with 576 individual clones, after the grid array gets bigger than that, it receives nothing from Cinema4D. Our test LED wall has about twice that number of pixels, so it would be nice to model that accurately in Cinema 4D (I know that I can fake it with TouchDesigner workarounds, but I'd rather let Cinema do more of the work). If anyone knows about a plugin that can output structured user data over a network where I can define my own messages, I'd be happy with that. If not, what UDP limitation am I running into here? It doesn't seem to be a TouchDesigner problem as it can receive UDP packets on the same port from other. But why would Cinema4D just stop sending data? I tried adding another light UDP server, but got no data out of C4D on that either. This is a very primitive server connection, so it could just be that, but I would love to know how to output more pixel data if I could. Thanks for any help you can provide!
