@dillthekraut thank you! I have added a physical map and will probably use some kind of gobo or iris in the end

@skulpture thank you!!!

@dbini thank you! that's the thing, I will be working in a pitch black space and every light 'leakage' is bad. I have added an analog mapping, without subtracted center circle as it's pretty difficult. But it looks already better this way.

 That's a very good suggestion. There are special projection screens which are black on purpose. With a black background, you get a deeper contrast, especially in a surroundings which are not perfectly dark. E.g. with a lot of ambient or even direct light to the screen. A white screen reflects more of the ambient light, which makes the dark part in the projection brighter. With a darker screen you can compensate this. But you might need more power to push the bright parts of the picture.

Thanks, all.

I did wind up going the OSC route. I haven't touched this material in a while, so it took a bit for my brain to adjust in the darkness.

But, yes:

In Isadora: OSC Transmitter to ETC Eos on the same Mac. Gadget is now outputting correct DMX as tested via a DMX tester. Fabulous!

Final hurdle was switching the OSC transmitter to "on" in Isadora.

Thanks for the support!

covers the basics, if you look at the resources that are included on the topic above you will see that you can also control channels

Hey everyone — I'm back to the 3x3 video wall and trying to see if it's possible to get all of the outputs sent from my two networked macs:

Mac Studio M2 Max, 2023, 64GB Sonoma 14.6
Macbook Pro M1 Max 2021, 64GB Sonoma 14

I'm sending 4 stages (1920x1080) from the MacStudio to the Macbook Pro via NDI. The Macbook pro has a display link tripple tap from pluggable, plus I'm outputting via hdmi adaptor one of the thunderbolts. Frame rate, load — all look great. When I look at the incoming NDI signals on NDI Video Monitor, they look great. But when I output stage on izzy it does nothing but stutter. 

Scratching my head here and haven't found any recent threads on this. Any thoughts? 

@orozcom

You can simply sent OSC commands to the ETC Eos software.

Hi, All,

I’m designing a workshop to show how audio levels can influence light intensities using Isadora. Previous Isadora patches have included Audio Watchers>dx DMX actors. I used to use an ENTTEC USB DMX Pro - which worked fine - but I was hoping to use an ETC Gadget II instead. I don’t have access to the ENTTEC box now.

Has anyone had any success with using the Gadget to receive DMX instructions directly from Isadora?

I have some more testing to do, but I’ve yet to have the Gadget even show up as a serial output option, whereas the ENTTEC box was plug-and-play.

Is there an alternative to doing this that I’m missing?

Another option, since it seems you may have more light than you require, you could change the projection surface. Likely you are looking at a white surface (wall) for projection, but if you make the wall mid grey, it will consume more of the light.

Try your projection test on a piece of black construction paper and compare.
