Hi. For reference, this site is dubbed as "Greyscalegorilla" for Houdini. http://www.entagma.com/category/tutorials/

Thanks for the clarification @ABMotion. This clear things up! Thank you.

Got to admit that Houdini presentation was amazing. I thought people only use Houdini for VDB stuff and particles. I guess I was wrong. Houdini is more than that.

Thanks @ABMotion for the response. I am new to Python but took me a while to figure out. So basically, I cannot locate the "Find" command in C4D documentation as it is actually a generic Python command. I was under the impression that since it is preceded by a dot (.), it is under the GetName() command. Same thing as doc.GetActiveObjects. GetActiveObjects command is under the doc. However, I thought the int() command returns an integer. But why does the code work when the what we are searching for (name) is a string and not an integer? Thank you for your time.

Hi, import c4d from c4d import gui #Welcome to the world of Python def main(): name = "cube" c4d.CallCommand(100004766) objList = doc.GetActiveObjects(c4d.GETACTIVEOBJECTFLAGS_0) for obj in objList: if obj.GetName().find(name) == int(-1): doc.SetSelection(obj, c4d.SELECTION_SUB) c4d.EventAdd() if __name__=='__main__': main() The whole script works. Just wondering how to read this particular line. (The line after the For loop command) In the docu, (1) GetName requires a string. However, in the code referred, it works despite not having a string. This gives me the impression that .find() is the string. Okay maybe it is, but (2)where do I locate the find() command in the docu (tried searching but there were several find commands and they are not specific to names). Lastly, what does this mean (3) command means int(-1):? Credits: The code is lifted on this thread https://www.cineversity.com/forums/viewthread/1305/#4453 Thank you for your time.

Hi @graphos RE: print objtList. Thank you for the response. It works as expected. RE:"#And here you can simply iterate over the list as you do normally". I'm not sure how to use this but I'll try to figure it out. Thank you again!

Hi, Is there a way I can get the data of a specific object in the multiple selected objects? For instance, I was selecting multiple objects in the following order. Cube Sphere Cone Cylinder. I was under the impression that the order would be 0 = Cube, 1= Sphere, 2= Cone, 3= Cylinder. But when I hit print doc.GetActiveObjects(2) I get a Cube instead of the Cone. Is there a way to cycle within the list using the GetActiveObject command? Thank you for your time.

To be honest, GI is massive rendering over-kill if you are using the default renderer (Standard/Physical) But if you use external renders, it is quite reasonable. This is actually why people use external renders because they are fast. There is an old way of faking GI. Basically, you render your scene without GI. Then Render an Ambient Occlussion Pass. Then composite it in the software. Then you'd get a decent overall illumination. Good luck!

Hi @jed Thank you for your response. Unfortunately, it's not what I am after. RE: your python. It is an interesting indeed. Just saw the file. The only problem with it is that it moves when you scrub back and forth. For instance, if you scrub from 1 to 150, it functions as intended. The cube raises up. But when you scrub to 150 to 1. It still raises up. By theory, it should move down instead. Srek from CGTalk also posted a solution which mimicks what I was referring. It works well with the position but not quite so with rotation. I have yet to check it deeply. I have mark the thread as solved to prevent any more trouble. But be it noted that your effort is not in vain, in your python script you actually pointed what was obvious: Just manually input the constant figure rather using a node. So that was what I did. Instead of the Cube as the input, I had the Cube's PSR instead (hardcoded)as a constant node in the Math node. It's not automated but it should work for the next projects. RE: Character string. Yea you are right. I never knew about python that can read the length of the string. That will surely come in handy in the future. Thank you again!

@jed Sorry for the confusion. Yes, this is what I am after "A = A + B is a loop" It is a loop. To be honest, I'm not familiar with Python or Xpresso. How do I do this? "Making the loop scenario only execute when the value to be added changes is easy in Python." Also I am not sure about this "and write to, read back etc." Sorry for the trouble.

@ABMotion Thanks for the link. RE: Srek, I'm still not sure. I still have to verify the rotation parameters. But the Position setting is what exactly what I want. RE: from above. Here is the file to illustrate the problem with that set-up. The child should rotate within its own axis rather than the parent. So hopefully you can see now why I wanted this equation Existing Object's PSR (A) + Arbitrary Variable Amount (B)= New Object's PSR (C). The equation above does not take bias against the pivot point unlike the normal Parent/Child hierarchy.

@ABMotion RE: "Why not move the Cube by 5 in Attributes Manager?" I certainly can, but I am driving that Arbitrary Node with a variable. Not just by 5. That is only for representation for simplicty. What is the action you're wanting to use to move it by 5? I want to move Object B by 5 and have Object A by the same amount. Why not use hierarchy? I cannot. Why not use constraint? I cannot. I need it thru expresso. Now come to think of it, in summary it is like doing Parenting but through Nodes. Is that possible? P.S. Sorry if this confuses. Should have explained it much better but I guess the Parenting but through Nodes should clarify.

Thanks for the reply.

RE: Trying to achieve. I'm doing a facial rig that have multiple pose morphs and multiple joints within that morphs. With controls that does not reside with its controlled joints. It's somewhat complicated. So the illustration file is really the clearest I can provide. With your solution, when I scrub the timeline, the Cube moves. (That was the problem earlier. When I try to change something, any change, frame or a simple click, the cube moves. It should not). It should only be incremented by an arbitrary amount (in this case 5). Regardless of what frame I am in. So in your question, Do you want A to increment by 5 only one time? Yes, in one time only unless I change the arbitrary amount. Is that possible?

@ABMotion For better illustration, here is a video of the problem https://www.dropbox.com/s/g9i29v3vhwv5z34/c4d044_loopingProblem.mp4?dl=0 And the project file https://www.dropbox.com/s/708kq7x9vyoveso/c4d044_loopingProblem.c4d?dl=0

Thanks @ABmotion for your response. Yes, I only want to increment of B. But I don't quite understand in using Time node with the Frame Output. If you have time, can you explain a bit further?

Disclaimer: I have posted this question to other website but still unable to get an answer. Trying this out here. Thank you I need an operation like this where I take the existing position of an object and add an arbitrary amount. However, as you can see in this illustration, there is an infinite looping problem. As the object is the input and output itself. The basic equation would be like this Existing Object's PSR (A) + Arbitrary Variable Amount (B)= New Object's PSR (C). BUT the existing object PSR should remain constant. For instance, A + B = C 5+2 = 7. When you run the equation again by default it would be this. 7+2=9 and again. 9+2=11 An infinite looping problem. I need A to be constant at 5 (the original Object's PSR) I believe there is store node in the Xpresso editor where it store values. I thought it was memory node but it doesn't seem to work. Let me know if the above is confusing and I'll try to make another illustration. Thank you for your time.

Sent you an email. Looking forward :)

This animation reminds of that Harry Potter where Voldemort changes to Tom Riddle. Thanks for sharing!

I second this. Seems like an exciting idea! :)

Is this it?

That's a lot of features. Looking forward to the weighting improvements.

Thanks. Just found it. Looking good so far :)

Cool. The Club feature is also interesting! :) BTW, is there a way to revert to the old black version? I just find i a lot cleaner compared to the white. Just a preference.

I'm not a GPU render/user so if I win I wouldn't really put it to use immediately. But heard good things about red shift. Good luck to all! :) That's also my concern in the giveaway. How would you know if the participants are C4D user? would it be void if they are not?
