I'm currently working on a project using Rokoko and Isadora, and I wanted to try the tutorials from Guru Session #19. However, every time I try to open the tutorial file provided Isadora crashes. I don't know if this is because the files aren't compatible with my version of Isadora, or if it's because I don't currently have an Isadora license. I'm really hoping to work with a 3D puppet. Does anyone have any idea as to why this might be happening? Or any other way I could achieve the same results?  Any help is appreciated.

Hi all

I am following up on a timer that I made for doing presenter countdowns. 

The timer works fine and all is good.

I am now moving it to beingtriggered and set up via a streamdeck & companon

I have set up OSC and that aspect is fine.

My query is how I should populate the timecode parameters?

When I use the time code and trigger value it pushes the information automatically into the running time code. I am looking to create a button that has a specificed time/function that can set a specified value. 

I have half the theory in my head but i cannot work out the patch here. I am looking (via OSC) to hit a button on the streamdeck that populates the timecode actor I have but only push this information when I press the button. At the moment, it is doing this automatically and I just cannot see what I should do here to fix it.

Hopefully I am being a bit clear...??

Thanks in advance.

 Off topic: I've never heard of Brave Browser before - it looks amazing. Thanks, for the tip!

Bumping this thread - does anybody have some new ideas for a Slit Scan shader? or should we put in a feature request for a more flexible Slit Scan actor? (inputs for width of slit and speed would be nice, horizontal and vertical offset might be interesting)

Don't know what I did

 I would take note of which USB ports you are using, this likely is playing a role. (some USB C ports offer more features than others)

I somehow got Isadora to not crash with all projectors connected. I started switching the cables around and restarting then testing Izzy. Don't know what I did (right or wrong). But I'll take it as a win.  If for some reason it acts up again you know I'll be back.

Thanks for all your help. It's really nice to have help when you don't have a clue...

publishing an X offset of the input in the projector actor

 I believe this is working in this configuration, unless I miss understand. 

My input is 3000px by 1080px In IzzyMap, 

I move my rect to the far left and select each right side corner, and enter 1920 (this creates my 1920x1080 output selection) 

I right click the Rect slice, and publish the Offset X 

Then on the Projector, I can move my view from the left edge to the right edge. (-1 thru 1)

Am I missing something

You could also use a Composite rectangle IzzyMap Slice and publish the x offset of each corner of the input separately, but then you have to do math to keep the image centered.

Hi

I would strongly recommend watching Mark's (that Mark's) guru session on youtube.

The guru session is excellent at explaining the methodology and steps you need to take here. 

There is about 1hr 30mins of content and well worth the watch.

Link to Guru 12, HERE
