ASCII Effect in TouchDesigner

[@Dan-bx3mg]

If you've updated TD to follow along with this video, it seems that the lavender checkbox used for binding isn't interactable in the current version (TD 2023.11510). Use the drag method shown at 22:30 or an expression such as parent().par.Numchars instead. Other than that small hiccup, awesome watch! Great pacing and workflow

[@polyhop]

Interesting, thanks for the note! Once I have a chance to test this on my end I'll add some text to the video

[@Dan-bx3mg]

'Export and bind parameter mode "squares" inaccessible in 2023.11510?' on the TD forums led me to believe it was an issue with the update rather than my instance. Figured I'd throw a comment up because it was the only time in the vid I had to go off and look for help

[@polyhop]

@@Dan-bx3mg ah! It did sound funny. I expect it will be patched in the next update, sounds like a TD bug

[@theXshoter1]

thank you! and good to have you back :)

[@bjrnravlo-leira]

Great tutorial! Easy to follow, great results, great fun to play with afterwards!!!

[@blankensmithing]

Yessssss 🎉🎉🎉

[@kiwisan32]

great tut! very detailed approach and that's what i like🙌

[@LongTran-xw5yp]

welcome back! Pls keep making these. Willing to become a patreon also

[@polyhop]

That's the plan! (to keep making them)

[@magenta6]

Thanks for an informative and useful tutorial. You introduced some new concepts for me which are great to know. I appreciate the detailed descriptions about why you need to do certain things. Kudos!

[@YukikoOdair]

Finally got around to working through this tutorial! I'm pretty new to TD and haven't touched it for a few months - but the tut was super easy to understand and well explained - i feel confident knowing what to tinker with to get my desired effect! Thank you so much :)

[@laurengold831]

Thank you! I learned a lot from this!

[@AlmaTabernero]

Hello! Thank you so much for sharing this tutorial, it is amazing! I managed to follow your instructions. However, for the nVidia BG switch, although I see the image without the bg on my OP, once I connect it to the switch, it doesn't keep it that way. Could you share more info about that step? Thanks!

[@ethanproia]

Yessssss 🔥

[@lucareichhardt-w9s]

brilliant

Welcome Back :)

I'm getting one error in replicator callback, its saying "float() argument must be q string or a real number, not 'td.Shortcut' , Context: (Parameter: Nunber of Replicants)

[@polyhop]

Double check the script, it should be parent().par.Numchars which should end up as an integer assuming you created the parent parameters correctly. If you're still having issues please reference the point in the video where you're having trouble (in case I misunderstood where the error is occurring.)

[@Shirokokun]

@@polyhop the point is i executed the whole thing , and I achieved the same result as well. But that error is still there , is there any other socials where I can share you the screenshot? Or anywhere, where I can contact you.? Maybe it's my system thing but I'll share with you the exact problem.. even though your tutorial actually worked . I achieved the desired result

[@polyhop]

@@Shirokokun Strange. And you're using TD version 2023.11340? I don't see any issues when I load the project file in the newest version at least. Are you on a Mac? As far as sharing the result, you can find me on Discord. I'm in the TouchDesigner Discord group for instance, same handle, or through my Patreon (though that is paywalled.)

how to remove the white color on grid at (11:33)

[@polyhop]

You can toggle off the render flag (purple dot on the GEO Comp) if it's still showing up in your render. Unless I'm misunderstanding the question.

[@so0ofii]

with the viewer active in that node, you have to press "W" to turn wireframe mode on

[@Shirokokun]

@@polyhopactually when I'm also changing the torange in math to (parent.par.Gridres-1) it's just showing one solid rectangle. But the moment I keep it without -1 , it's showing 5x5 boxes in grid but I also have a Problem , i.e the rectangles in grid is solid unlike yours which is just outlined rectangles. can you help with it? ill continue with the tutorial as for now with this set up only , I'll update if that caused any problems in output. but is possible let me know whats the difference

[@polyhop]

@@Shirokokun Removing the -1 will show you a "grid" because you're adding a small amount of space between your squares. I imagine the solid rectangle is because you need to point a wireframe material at the grid. If you don't see the wireframe, try moving it forward in the z axis as when both are placed at 0 you can get what is called "z fighting" (I missed covering this in the tutorial, but it's an important fix for something that has inconsistent behavior.) Either way, you should be able to get a similar final result.

[@slothyboi3473]

my "ascii" geometry is presenting an "all ops must generate the same number of instances (have the same length)" and i dont really know what thats about! i hope i can get some help

[@polyhop]

Check the resolution of all your instancing TOPs (middle mouse button on an OP tells you the resolution quickly.) They all need to be the same resolution or you will see this error. It's possible that the remap TOP needs to be set to use the UV for the resolution for instance.

[@PaulikasKarolis]

Hi! How could I adapt this to 1920x1080 resolution? Thanks!

[@polyhop]

You'll need to adjust the resolution of "render1" for 1920x1080, and make sure the grid is both set to a 16:9 ratio in size, and the corresponding rows and columns. Additionally your input video will want to be 16:9 aspect. That should at least get you going in the right direction!

[@PaulikasKarolis]

@@polyhop thanks! went through the operators, but encountered an issue with the ortho camera, it seems like it needs to be adjusted manually now, but breaks the dynamics when changing font size and so on. Solved with a fit after the in top and changing the render resolution to 16:9!

[@polyhop]

@@PaulikasKarolis Ah yes you'll need to adjust the camera ortho width too. Was thinking in my head of what would need to change and missed that detail :) Glad you found your way to a solution!

is this project file available via your patreon ?

[@Mr.Nobody2077-u1u]

Not to ask a dumb question, but if it only works with nvidia. Is there anyway to use it on amd?

[@PedroUribe-g5p]

Keep getting a vulcan error when I try to reopen this patch.

[@polyhop]

I am able to open this without error in both 2023.11340 and the current build (2023.12000.) You can always rename a file CrashAutoSave.toe to access it in safe mode. Then you could do things like reduce the size of the grid / render resolution, which could cause more GPU usage, or disable components so you can turn them on one at a time outside of safe mode to see what is causing the crash. See docs.derivative.ca/Troubleshooting_in_TouchDesigner for more on that process.
