No, sorry. If you look at the MAXON page on special tracks here , you'll understand my quip earlier about my trial and error method. I find the SDK v hard going, so I usually try 'drag and drop' a data field into the Python window. This often results in usable code, with a bit of editing. It worked for the start time field, but when I tried with the sound file, it mysteriously said my music.wav file was called '10.0'.... You could ask at CG Talk or the C4D Plugin Cafe - the latter has some very tech types, but they also speak in Klingon code-speak. https://forums.cgsociety.org/c/software/MAXON-cinema-4d https://plugincafe.MAXON.net/ code joke

Cubase Elements is amazing value at about £85 UK.

Yes, no scrubbing. When it comes to triggered sounds, I've had some success using Audacity to record in real time. If the track length doesn't exactly match, AE has time stretch.

I'm not sure how to swap tracks the way you suggested. Is it essential to use timeline sound ? The regular sound node is easier to program ie start time, swap tracks. AFAIK it doesn't render, but there's ways around that - eg record 'what you hear' in real time and add it in post. See snip

This uses a python node kill.zip and I used trial and error...

I was watching this kinda dystopian film last night, where a lot of the population had to sit front of screens all day, connected to a master mainframe, and solve mathmatical, graphical puzzles. The puzzles were based on cubes - see snip of 2 typical screens I thought 'sitting in front of a screen all day, looking at cubes - hmmm, this sounds familiar...' film was The Zero Theorem (2013) https://www.imdb.com/title/tt2333804/

If you go menu > script > console, that's where python prints error messages (and non-error prints). It says that's because you had a circle plugged in. Make it editable ie a spline, and the yellow goes away. When you click compile on the python window, and it says OK, it's really just a simple syntax check.

I think I've fixed it def main(): global Output1, Output2, Output3, Output4 if pos == 4: Output1 = 0 Output2 = 0.5 + twist Output3 = 1 Output4 = 0.5 if pos == 5: Output1 = 0 Output2 = 0.5 Output3 = 1 Output4 = 0.5 + twist import c4d from c4d import utils #Welcome to the world of Python def main(): global Output1 if not SplineObj: return blah = utils.SplineLengthData() # blah = dummy var blah.Init(SplineObj) # name of spline Output1 = blah.GetLength() arrowTool_0001.c4d I'm not too sure about this line ' sld->Free(); ' let me know if it works ok edit - according to lesterbanks, the line I was unsure about would be blah.Free() # free up memory used by new spline class instance might be required...

I found that adding a field made this work - although I'm not sure why

Sorry - don't understand. Give numerical examples.

Are you changing the ref plane uniformly or per axis, by size or scale? Are the other 2 going to keep their aspect ratio ?

Are these editable planes or primitives.

Apologies for my vague instructions - it was kinda late Dragging a field onto a node works for any node, and is quicker and more accurate than going through submenus - where items often have similar names

I don't use pose morph or set driver, but as I understand SD it just makes an XPresso tag with a range mapper with 1 to 1 correspondence. So my guess is to make an XP window, drag each pose tag in, for the driver pose drag the sliders to the RHS to make a port and ditto LHS of the driven pose. Then connect with wires. If both are 0-100% there shouldn't be a problem and a rangemapper won't be required. [ RHS of node is output, LHS is input ] might work...

Is this @Vertex Helix in the park ?

If you mean write data to user data from within Python, so it can be read from XPresso - make a null to hang your user data on, and create some data identify the null in python - SearchObject etc, and drag the data field into Python. This makes the correct syntax, but you may have to edit the text to suit. Here I'm writing True to a Bool - BTW the 2 in the code refers to this number try to use correct data types (bool, int etc) - XPresso allows mixing datatypes, but Python gets a bit picky sometimes.

I've got to admit, I'm a bit out of my depth with your type of button. I tend to use 'ordinary' user data buttons - like this button.c4d

I think this works - makes a list of nodes in the XP window, searches for a constant node by name, then writes a value. I used frame as dummy data. I find it easier to read + write to user data write2me.c4d code is from a reply in cg soc a while ago. you might be able to adapt it.

I think using a formula node and X group is a bit over the top

I'm not sure if replacing 'order=ROTATIONORDER_DEFAULT' with 'order=0' is correct. ROTATIONORDER_DEFAULT had a color that suggested reserved word ie correct syntax, but SDK says parameters order(int).

I might have fixed it by trial and error. I found a couple of Python outputs that should have been vector, but console was still borking at rotation order. I changed it from ROTATIONORDER_DEFAULT to order=0 and the yellows went away. MOCAM_R20v09.c4d well, things now move in the viewport...

@C4DS is a 'global' required in the code quoted above ? # construct a matrix from Position and Rotation, # input ports are Position and Rotation, output prt is NewMatrix import c4d def main(): NewMatrix = c4d.utils.HPBToMatrix(Rotation, order=ROTATIONORDER_DEFAULT) NewMatrix.off = Position  I also noticed a box 'TimingNodeStart' in the XGroups that doesn't seem connected

I see a lot of yellow Some Python troubleshooting tips - There's a log of python errors in menu > script > console. If you have several Python nodes, you should rename them Python 1, Python 2 etc to see which node the error message refers to. While XPresso is very forgiving when you mix data types (eg connect integer to string) Python is not. You should go through all the Python nodes and check port data types. If you hover the mouse over a port it shows the data type. This must match what the code is expecting. Here the code expects a vector but the port is real in this case you should double click the port to remove it and make a new one of type vector You can get info on unfamiliar functions using search at C4D Python SDK good luck !

@C4DS thanks

@C4DS a related question. What does -> mean ? I don't think I've seen it in Python, but have seen it elsewhere.
