What You'll Learn in TouchDesigner Beginner Crash Course:
- The fundamentals of the TouchDesigner paradigm: Never used a node-based programming environment before? I walk you through the basics of TouchDesigner logic and workflows, explaining exactly what nodes and wires are and how they work. This includes a walkthrough of the basic settings and preferences you can leverage in TouchDesigner that set you up for success and make your life easier.
- Discover all six of the operator families used by TouchDesigner, and how they integrate with the TouchDesigner workflow. I’ll walk you through an example project for each of them. Operator families include…
Signal processing and channel data (CHOPs)
Compositing and texture manipulation (TOPs)
Procedural 3d and rendering (SOPs)
Data processing (DATs)
Materials and shading (MATs)
User interface and controls (COMPs)
- Real time generative graphics basics: From generating graphics using dynamic noise data in real-time to audio-responsive 3D geometry, we’ll go through multiple examples of how to start creating beautiful generative content in TouchDesigner. Interactive, immersive, generative media is the reason you’re investing in learning TouchDesigner, and my course helps you get started creating it right away.
- Simple, day-1 preset system: Most TouchDesigner preset systems are too complicated for beginners. With my day-1 preset system, anyone can start creating presets without any prior TouchDesigner experience, which is a massive advantage most people don’t have when they’re starting out.
- Time-saving keyboard shortcuts and application tricks: This should be intuitive, but it’s not. Having these under your belt from the get-go is huge time-saver.
I've been learning online tutorials for almost half a decade, ranging from software like blender, unreal, davinci, and literally I cant express how easy you made it to understand a software so easily! Amazing teaching skills !!!!
We're so glad to hear that! Thanks for watching :)
Absolutely loving this series of TD videos - thanks so much Elburz.
Our pleasure :)
Fantastic tutorials. Thank you for your generosity!
Our pleasure, once you're getting to the end of this course, I think you'll really enjoy going through our more content focused videos as well :)
Keeping learning TD along this amazing intro. Thanks for sharing!
We’re glad to hear it! Thanks for watching :)
muy buenos los tutoriales, excelente. muchas gracias por el trabajo y la dedicacion. Iba a hacer tutoriales para generar visuales faciles sin entender nada y justo di con estos videos , agradecidisima al internet y a ustedes. Estoy disfritando mucho aprendiendo touchdesigner
Thanks for the great and clear tutorial!
You're very welcome! Thanks for watching :)
Thank you so much for these tutorials.
Our pleasure! :)
THIS ONE REALLY WENT CRAZY
I am gratefull to you for amazing teaching and knowledge of all!!!
Glad to hear you found it helpful! Thanks for watching :)
Thank you so much for the tutorials. At the end I just started messing around and chopping up all kinds of parameters as a curious artist does. But how do I disconnect the chops from the parameters? Hopefully that’s in the next video. 😅
Our pleasure, thanks for watching! Just in case you didn't see the comment on the other video, to disconnect a CHOP reference from a parameter, you can right click on the parameter and click "Delete Expression". Hope that helps!
Thanks this is so helpful
That's great to hear, thanks for watching!
Amazing
Appreciate it! Thanks for watching :)
On my TD version, setting Alpha to 0 makes it transparent
From an older answer to another comment: "If you can try going to Edit at the top menu and then Preferences. If you go to TOP settings, try changing the Viewer Background between Black and Checker board and see if that solves the issue. Let me know!"
Hi, really appreciate this amazing video. I have met some problems while connecting a CHOP operator to the circle's opacity parameter. It only showed 3 options - 1. Export CHOP 2. CHOP Reference 3. Current CHOP value, instead of 5 options that you showed in the video. Does this happen because of different versions of software? Mine is 099 (Mac Version).
You can use CHOP Reference, that will be the main you'll almost always use. Yes this was a different version of TouchDesigner as they were changing the menu items.
Thanks always!, Quick question here! I would like to use the sound of movie file in for the movie file out mixed with other sound from audio file in. Seemingly I could only find to use audio file in to movie file out. Please help!
Great question! To mix these audio signals together, you can connect the outputs of the Audio File In and the Audio Movie to a Math CHOP. Within the Math CHOP, set the Combine CHOPs parameter to Add, and the two audio signals will now be mixed together. Add a Null CHOP after the Math CHOP, reference it within the Movie File Out, and you should be good to go!
One thing that’s worth testing is the mix of the two different audio signals. I’d take a test recording to see how the levels sound first, and then adjust the levels from there. The Audio File In CHOP has a volume parameter that you can use to adjust the volume, but the Audio Movie doesn’t. If you need to reduce the volume level of the Audio Movie CHOP, connect a Math CHOP directly after it, and decrease the Multiply parameter from its initial value of 1 to lower the volume. Hope that helps!
@@TheInteractiveImmersiveHQ thx a lot! Let me try!
hey do anyone have any idea why there is only three options in my transform panel and i cant find any (RELATIVE CHOP REFRENCE ) when i was parenting my x or y to the over 1
Great question -- you can use the _CHOP Reference_ option to make the connection. Relative CHOP Reference has been replaced in newer versions of the software.
The _Justify Horizontal_ and _Justify Vertical_ settings are greyed out in the newer version because they are not used in any of the Pre-Fit Overlay modes besides the _Native Resolution_ option. If you want to have access to those settings, change Pre-Fit Overlay to _Native Resolution_ . Hope that helps!
I am using a MacBook Pro with my mouse plugged in and I have followed along with all of the instructions in building my network, but no mouse data is being picked up? Everything is just the same in the network as in this video but the white sphere won't react when the mouse is moved. Please could you advise? Could this be a mouse incompatibility problem and if so is there a quick work around? Thanks for your help.
You have to make sure the network is "playing." Hit the spacebar lol.
@@maxwellbliss thank you
Hello, I have a question. How can I restart the movement of a transform top with a key?
Greetings
Unfortunately with this current method there's not a good way to re-center the circle texture/CHOP channels as they're directly connected to the current mouse position.
Instead, you might try this method: connect the tx/ty channels of the Mouse In CHOP to a Slope CHOP, and then connect the Slope CHOP to a Speed CHOP. The Slope CHOP will generate acceleration values, which are used to generate new position values in the Speed CHOP. It's worth setting the Limit Type parameter in the Speed CHOP to Clamp, and then the Minimum to -0.6 and Maximum to 0.6 to keep the Circle's position within the texture (otherwise it'll be "offscreen" most of the time and hard to find).
Finally, add a Keyboard In CHOP to the network, and connect its output to the second input of the Speed CHOP. If you've connected the output of the Speed CHOP to the transform parameters of the circle texture, you'll then be able to reset the position back to zero by hitting the 1 key on the keyboard. Hope that helps!
When I connect the CHOP Reference from Null to the Over TOP, I don't get the animated line with the arrow showing a "cooking/live" connection. Everything is working though... I am on the latest version of TD. Any ideas? Thanks!
Great question! This might be due to accidentally having hit a keyboard shortcut. If you hit the x key on the keyboard, it will toggle the display of those connections on and off. Hope that helps :)
@@TheInteractiveImmersiveHQ Thanks, that was it! :) Keep up the great work!
hey guys! I'm finding this problem - my mouseIn parameters aren't changing as I move the mouse - they're static. I also don't get a Relative CHOP reference, just CHOP reference. I've repeated all steps 3 times, same problem. Any ideas what might be wrong? Thanks in advance :))
RESOLVED Golly I'm dumb XD It. was.paused. I just hit the play button bellow and suddenly, magic :D I won't delete my dumb question justy if anybody happens to have the same issue 😅
@@dreamseemstudio7545 I talk about this all the time, it happens even to pros! It happened to me the other day as well :) Always good to put it on the list of troubleshooting steps since it's so easy to accidentally pause it haha. Glad you got it resolved !
hey, i'm having an issue with the translate tx value. For some reason when I attach the nulls tx (during the steps around 9:00) to the over, my circle disappears completely. This could be because I only have the free version of touchdesigner, so my res is set at 1280x720 to mimic 1920x1080 .. but my ty value works just fine and is responsive! dunno what the problem is, can anyone help me out ? :)
When you look at the CHOP channels that are being referenced in your translation, what value range do you see? Are they from -0.5 to 0.5?
@@TheInteractiveImmersiveHQ so, I was actually able to fix it--- I had TouchDesigner pulled up on my second monitor, and it seems to affect the CHOP channels in a weird way.
@@lindsayclifford1685 how did you fix it? im trying to set up touchdesigner so it only picks tx value from mu second monitor but idk how do that
@@lmadrina6207 You have to set the monitor you are working on to your main screen in your Windows settings...or work on the other one.
Hey man, i have quick question, why is it that my "constant" is always showing transparency viewer screen whenever i zero out the Alpha value? cuz your screen shows constant operator's viewer port as black box but mine is showing transparent box
I think this might have to do with a setting - you can choose whether or not the TOP viewers will show transparency as the checkerboard or black via the Viewer Background option on the TOP tab of the Preferences window. That said, it can be helpful to leave the checkerboard on as you can clearly see the areas of the texture that have an amount of transparency to them. Hope that helps!
@@TheInteractiveImmersiveHQ Greatly appreciated for the awesome feedback! Thank you!!. I'm learning TD during work hours when i have less work. and its really fun!! so Thank you !!!
Hello sir, when I change Alpha from 1 to 0 in 'constant' op my background is getting transparent not black. I got transparent background in Circle TOP by default too but You got it black. Am I doing something wrong? I use latest TD 2021.16410...
If you can try going to Edit at the top menu and then Preferences. If you go to TOP settings, try changing the Viewer Background between Black and Checker board and see if that solves the issue. Let me know!
@@TheInteractiveImmersiveHQ That's it! Thank you very much. I tried to change pixel format to RGB ( to get rid off Alpha channell ) but as a result, there were more problems in the later stages... This Crash Course and hard work are all you need to succeed in learning TouchDesigner!
@@dmotyllo absolutely! I agree that if you're able to have patience and perseverance that you'll be able to do great things going through our resources.
Hi, I'm having a problem... so at 12:01... I don't get a Relative CHOP reference, just CHOP reference and i noticed your parameters where at 0.3, mine isn't changing as I move the mouse. I saw someone had the same problem in the comment. I played the network.. it's still not working hellpp please
The CHOP Reference options have changed slightly since this video was recorded, but you can use the *CHOP Reference* option to replace the *Relative CHOP Reference* without issue. I would start by trying to make the CHOP references again, and then also make sure that the timeline along the bottom of the TouchDesigner window isn't paused (you can play/pause by hitting the space bar). Hope that helps!
@@TheInteractiveImmersiveHQHi yes.. it worked thanksss but the values still didn't change. I window was playing.
CHOPs get the party moving 🖤😎🙌🐇. Tx friends
Always 🪩 Our pleasure!
I keep having this problem with the resolution: file:///Users/iasmina/Desktop/Screenshot%202023-07-04%20at%2021.33.26.png
what should I do?
