 There's this non-toxic alternative to Vantablack, but it's still expensive: https://culturehustle.com/collections/black?gclid=CjwKCAiAjPyfBhBMEiwAB2CCInIilPTnBfRjAXwar33ch72_1J42loCScRRC8VLEKtd7cyObs6iiHRoCeXwQAvD_BwE

I was thinking about a ultra short throw but didn't know the focus limitations.

I'm now thinking an a completely other direction. I will double the gauze above 2m50 this reduces the brightness of the light falling trough a lot.
This way the light under 2m50 can fall on the floor and the light above can fall on the back wall where we will use molton as suggested above (or if somebody has some spare Vantablack laying around :) )

Let hope this works.

 I hope I am reading between the lines and that there might be a way to do that in future, as I requested in my feature request seven years ago

I wasn't trying to imply that we're currently working on it, just that it's on our radar as a feature that is often requested and would be very useful to add. I'd really like this feature to already exist or be in active development as well, but at the moment we've got our hands full with IzzyCast. (Though as a result of requiring a few new features for IzzyCast, we've added a number of handy updates to the Control Panel.)

the animator was putting files for me in a shared Dropbox folder, and as he revised these he was simply overwriting the old version in Dropbox. Meanwhile the composer is sending me files via GoogleDrive, also overwriting old versions with new, and the script from which we were generating the captions was shared via iCloud. I can't copy and paste these from their various locations into the same folder as the Isadora file, else I won't get the updated assets. 

You can ask your collaborators to not use three different platforms to provide you with files, e.g. create a shared Dropbox or Google Drive folder before the production and tell your collaborators that that's where the content needs to go. Additionally, putting everything in the same shared Dropbox or Google Drive folder means it's easier to port the show to a different computer since you could just download it. I've done just this for a number of productions and when I finish I desync the folder from my computer and the online folder becomes my archive for the show.

i would go for the widest lens possible and shoot the image from the grid straight at the scrim. if you try to go at a steep angle, you may have trouble focusing the image as the bottom of the scrim is nearly 5m further from the projector than the top of the scrim.
Using a 0.5:1 lens, or wider, will mean that your image on the back wall is going to be huge, and therefore less intense. If possible, rig some black molton curtains across the back wall - the wavy wibblyness will distort and absorb at least some of what's left of the image.

Also - a dense scrim like sharkstooth gauze will absorb more of the image.

@kdobbe

which projector are you using to get an image 10m wide? most ultra-wide (mirror-based) systems have a throw ratio of about 0.2:1, but only go around 4m wide before they lose focus. i have a couple of old Optoma short throw projectors that have fixed lens at 0.5:1 but they are only 3500 lumens, so only suitable for projection up to around 6m wide in a very dark space.

@hentho

Yes that’s the expected behavior for the checkbox.

@Woland

...and by the way: one of the documentation stated that it is very important to ckeck "Auto Detect Input" in the Stream Setup Window. But every time I reopen the  Stream Setup Window the checkmark is gone, and I have to re-check it when trying a new setting. Is this at leats normal behaviour?

@woland

Thank you for your answer and links on how to connect Isadora to ETC/OSC network.

One day of reading and trying, I have to give up now.

My laptop (running Isadora) is/should become part of an already existing rather big ETC setup (2 x EOS TI, 2 x ION, several pug´s, nomads, etc.) where I can´t change any settings in the EOS shell. However, we have other applications running, that are using/receiving ETC´s OSC just fine, but Isadora does not. I am aware that it´s me and not the application. I am in tears, but have to stop now.

Thank you for all your support!

If you have access to an ultra wide lens… You should be able to do this via rear projection. My Ultra Wide lens creates approximately a 2 to 1 ratio of width.  So a 5 m distance will give a 10 m width… I am doing a project right now with very similar dimensions.  Although, I have a front and rear projection screen, so perhaps the scrim might be problematic.

Totally agree my projects are  spread across 3 drives as added media happens on the road no time to tidy up. 

Have now upgraded my comp and version and to transfer all my projects @ links to media will take many hours
