@skulpture Thanks a lot, I didn't now that ! (I'm on a mac) DO you know an Isadora compatible mac version of that ?

Hi all,

Wondering if you could share some light on this behavior. We have an installation that transmits stringified JSON data over a local network via OSC into our Isadora file. We've been using this system just fine for the last year with no issues of stability or data loss. However, upon our recent upgrade into Isadora 4, Isadora no longer autodetects, or manually detects any data coming from our server. We've verified that Isadora 3 still functions as expected, even while I4, with the same configuration does not. 

Were there any major changes to the OSC system under the hood in the update? Or any configuration changes we should make? Any advice would be greatly appreciated. Thanks.

@mark_m

as suggested by @mark_m connect a Pulse Generator to the trigger input of the Lines actor, at 30hz, then as you change the start and end positions the drawing will update at 30fps.

The defaults for the actor has a white line drawn on a transparent background. If you are layering this with other projectors, you should set the projectors blend input to Transparent so that the alpha channel is used.

 I think the release notes are probably the best documentation of any breaking changes. In the case of Isadora 2 to 3, we had the shift to 64bit which killed some 32bit fx (thinking about FFGL 32bit here), these where really beyond our control. We don't get rid of things as we add updated/replacement features, instead we take the approach of making things 'classic' and phasing them out so that projects have an easier update path. 

Some search features would be helpful. I would love to get a report for any given actor that provides the breadcrumb path to any instance of an actor. These are things we have talked about and I hope we can get into the software.

Try attaching something to the trigger input of the lines actor, like a pulse generator, for example.

It's not the issue of the displays not consistently appearing in Isadora in the right order, which yes, an EDID emulator (mostly) solves, but the fact that the display order in the OS never matches the display order in Isadora.

I have a lot of trouble using the lines actor. But maybe I'm using it wrong.

If for example I have a picture player and then put a few line actors in between that and the projector, the preview window/stage goes completely black.  But if I toggle their bypass to on and then off again, the image on the stage appears again. Someties though toggling it doesn't make it reappear and then I have to delete the line actors and recreate them.  

Another issue with the lines actors, is that if I'm trying to position them on the stage by changing the position values, they don't move on the preview window or stage. I have to actually bypass them and re-enable them to see their position updated. So its a very painstaking trial and error to get them positioned where I want them.

I looked for a lines tutorial in case I'm not supposed to be using them the way I am, but couldn't find one.  Just the fact that they behave so strangely and inconsistently suggests it might be a bug. This is in both the latest and previous versions of Isadora 3 and 4 on Windows. 

@jfg You might need an EDID emulator: https://www.extron.com/product... 

@jfg  Hi!  I had this problem months ago and its 100% solved now. Just buy some $20 EDID minders and plug them into the back of your projectors in between the HDMI slot and the HDMI cable.  Never had projectors out of order since then no matter what I do.

Hi,

Recently a show i made many years ago started touring again. I made the patch in Isadora 2 and it took me some time to go over the file and make sure everything works in the newer version.

While I was doing this I was wondering, "How do other people tackle this challenge":

On a technical level:

• Are there ways to know what might brake when upgrading?
• There was a plugin that wouldn't work anymore so i had to replace it but it took me a long time to find every scene where the plugin was used (in a user actor that was inside an other user actor). Is there a way to find them all. 
               I deleted scenes, saved, and restarted until i didn't get the missing plugin popup on startup so i know the scenes they where in.

But also on an artistic level

• Some scenes I really didn't like anymore, should I change them and make them how I would make it now or leave it as it is because that was how the show looked like in the past. 

I'm very curious to hear your thoughts. 

With kind regards
GertjanB
