The Enttec DMX control actor is a little difficult to set up, but if you have the correct channels set, then it should function in the same way as a lighting desk. The times when I had a problem controlling lighting through the Enttec was fixed by experimenting with different speeds in the Serial Port setup - sometimes the default speed is too fast for the device.

I'd recommend building your file using the OSC Address Listener actor.

That way, whatever tool you made to do this can be put into a User Actor and used in any file instead of being locked to this one specific Isadora file because of Stream Setup.

 It's showing the size of a blank character (space). Notice that if you leave the 'text' field blank or put a space in it, the text width/height doesn't change. Seems like a bug. I'll log it.

Here's another (admittedly more complicated) way (check the top right Comment): dynamic-subtitle-background-2026-04-24-4.1.3.izz

I am using the draw text actor's measure mode to scale a shape which is the background of the text. Like the background for subtitles.
For some reason, even when there's no text input, the text width and text height have values, when I would expect them to be zero.

Thank you! I was able to use the stream settings to help troubleshoot my issue. The data was coming in under channel 0 in the stream settings viewer, once I changed that it is running fine.

By default Isadora uses port 1234 for OSC. This can be changed in the Isadora Preferences if you can't set it in the app sending the data.

You can use the stream setup dialog to detect incoming values. (located under Communications/Stream Setup). By checking Auto-detect Isadora will list all incoming values. This makes it easier to tell if you app is sending in an acceptable way, or needs some config changes.

Any incoming values will be listed in the blank space, with a few settings. The Channel number will be used to grab this incoming value in the Isadora patch.

Here the OSC Listener is used to 'grab' the OSC value. Channel '1' is set to grab the first address defined in the 'Stream Setup' dialog.

Hello,

I am trying to send position data from a scenic automation software (Creative Connors Spikemark) via OSC to Isadora. My goal is to have a projected image follow the automated scenery. I was not able to find a plug in or OSC dictionary for Isadora to receive the position data. Is there a way anyone has found to do this? 

Thanks!

Sales & Licensing questions are better to ask using the support ticket link in my signature.

Our S&L staff don't use the forum.

Just curious if there is still a way to purchase licenses to earlier versions of Isadora. Here I specifically am wondering about 2.6.1.

I am looking to permanently install a art piece that was built using a lot of the old 32 bit actors so I would need to get a license for version 2 on the computer i install at the location.

Sounds like you're trying to control an LED Par via DMX with Isadora, but I'm a little confused by your mention of a projector.

Anyway, all you need to know is the DMX address of the LED Par, and you should be able to use this file by @DusX to control it: https://troikatronix.com/add-ons/dx-dmx-universe-enttec-compatible/
