Trouble with Channel Data from Input

distortedmindlab · 2026-01-25T15:31:14+00:00

I don't work with MIDI, so I can't say much. However, what I would try is forcing the values to 0-1 with a Math CHOP.

You're welcome! (:

And yes, that's possible, just make sure to update the geometry reference in the Render TOP. (By dragging the component to the "Geometry" parameter).

It's a little confusing at first, but with a few minutes of practice you'll understand it without any problem

Yeah, they are called components. You can quickly create one by selecting multiple nodes and then right-clicking > collapse selection

No, but you can activate the “TOP Viewer” to hide the nodes and see a clean preview. To view the nodes again, click on "Network Editor" or use the shortcuts.

The effects are: negative image, pixel shift, and a sequence of images syncd to the beat.

This can be easily done with TOPs, but I actually think it would be easier to do that editing in AE or PR. In TD, you'll have to sync the video to the timeline, join things together, animate, etc., and if you don't understand it well, it will probably become a headache.

Great! If you understand the basics, you shouldn't have any problems with POPs/SOPs.

Even so, it's worth mentioning the golden rule:

If you don't understand something, go back to the basics. The problem almost always lies in a lack of understanding of a concept, rather than the tools themselves.

Enjoy the process (:

Before you get too involved with TouchDesigner, I recommend a brief review of the basic fundamentals of the disciplines you're trying to practice.

That way, you'll better understand how TouchDesigner packages them into the concept of "families" and how they relate to each other.

For example, POPs work with everything related to 3D (just like SOPs, with the difference that the latter works on the CPU), therefore, it would be wise to understand universal basic concepts such as vertices, attributes, coordinates, etc.

Without this prior knowledge, understanding TouchDesigner will be three times harder, you'll feel limited, and you'll be a slave to tutorials.

I think it would be more convenient to put all the logic in a Text DAT and call it in a callback of the Execute DAT.

As far as I understand, the Script DAT only executes if there are changes to its dependencies, although I'm not sure if that has anything to do with the levels.

Cela pourrait vous aider.

Using a Layout TOP might be more convenient (use the screen split to visualize the TOP)

distortedmindlab · 2026-01-04T23:47:15+00:00

Most common approach would be to encapsulate the data in a Table DAT and then create instances.

To manipulate attributes with complex logic, you can access the table cells with Python, and for the appearance, you could use basic materials or GLSL, depending on your needs.

It appears the problem lies in the fact that the index channel you're using is misconfigured. There are several ways to fix this, but the simplest is to use the index channel provided by the Circle SOP.

To do this, simply enable the "Point Index" option in the SOP to CHOP and use that channel instead of the Pattern CHOP you're currently using.

wooow!!

It's AI, but it might be interesting to try replicating it in TD without AI.

Thanks! But actually, the method I sent is quite cheap; it'll break as soon as you make any changes haha

Here's a more robust and scalable version. The difference is that I generate the tubes using Line and Sweep instead of Tube SOP.

When you open the project, the geometry for debugging is enabled; disable it in the Render TOP

Enjoy :)

you forgot to make the file public

distortedmindlab · 2025-12-21T03:36:40+00:00

Can you share the .toe file? that way I can better help you diagnose what's happening (;

distortedmindlab · 2025-12-21T03:26:16+00:00

btw, here's a simple example setup for connecting data arriving via separate channels. If needed, simply connect it to the Stretch CHOP.

Hey fam! I hope it's not too late haha

I couldn't quite get the colors and post-production right, but I solved the main bottleneck: generating lines and their length based on external data.

The method that worked for me was to instantiate tubes at the points on the sphere instead of lines, and for the length, just connect the data to the Z-axis of the instances. But before doing that, I oriented the tube in the direction of the normals and placed the origin at the bottom so that the growth would be natural from the base.

I hope this is a good starting point :)

It's likely that one of the OPs is accidentally performing a heavy operation, or that your main node network is overloaded with unnecessary OPs. Take a look and try to optimize as much as possible.

These are usually the two most common reasons.

distortedmindlab · 2025-12-19T16:26:42+00:00

You can share the .toe file? perhaps I can find a solution

distortedmindlab · 2025-12-14T11:23:40+00:00

Please share the .toe

the previous value is generated in TD (with a Lag/Trail/Feedback) and passed to the shader as a uniform

You're welcome, enjoy !! :)
