But wait: did we make a custom masquerade.txt file for you that is different than the default? What does it say? Can you .zip it and post it here?
you don't. I used the normal masquerade.txt and it works with 0.9.2
I have also tried to use the masquerade.txt from 0.9.2 in 0.9.6 but without success. Same result.
thanks a lot

you are sooooo good. It works on both computer. On the MacBook Pro (USB 3.0) and on the MacPro (USB 2.0).
With USB 3.0 on the MacPro I have the same problem as Demetri79 but it is not important because it works with 2.0.
Another strange difference between MacBookPro and MacPro (or between USB 2 and 3) is the color video output:
- On the MacPro I get the video with the same little delay as the depth video.
- On the MacBookPro (USB 3.0) the video color picture is frozen on the first picture also if I switch the capture mode on "color"
On both computer the capture mode set on "color" show both picture (depth and color)
I find it a little bit confusing because there is also "both".
thanks a lot

More fodder for the mill... MBP 2012, 10.13.6 = simple viewer, as before, not working. You have the script error above. Thought I'd try the same process with iMac (Retina 5K, 27-inch, Late 2014) w
(AMD Radeon R9 M295X 4096 MB) 10.13.6 and simple viewer works, but with lots of faults in the terminal. - John (tried adding terminal info, but don't see the file I attached-sorry)
But 3D Puppet is not working as three.min.js is missing (JS Quaternion Calc Angle actor compile error).The js file is located next to the openni-tracker-tutorial.izz patch.
Someone any advise about this?

works still well. On the MacPro (USB 2.0) if I go out of the picture it takes 5-10 s to track the body and get the skeleton and sometime the skeleton get lost and I haven't find why it is coming back (could be 30 s) or not.
I think not so important because all the new computer have USB 3.0. I haven't these problems on the MacBookPro (USB 3.0)
record and play work well.
Regarding your question about the color mode.
It seems that we have 2 inputs
- Capture mode
- output depth
Our help file of the capture mode tell us that we can use the capture mode to tell or we wish to capture the depth / color and send it to the desired output.
Output depth overrides this behavoir and basically makes it send out a depth image while you said against the Capture mode that you only want a Color mode for instance.
I personally wouldn't disable tracking when you set it to 'Color', that is where the Body tracking parameters are for. I would be fan if we can just disable the depth-video output if we only tell Izzy that we wish to capture color. (Internally you can still fetch the depth map for the inner workings of the plugin, just dont send it out to the output of the plugin so that the video signal is cut)

Do people find this confusing? Should I change it so that, if the mode is set to 'color', body/skeleton tracking is simply disabled?
There is something confusing but for me it is that the capture mode "color" or "both" give the same result at output. I think it will be more clear to have only 2 possibilities: "only depth" and "color+depth".
I think it is the purpose of this actor to always track the body even if you only use the color picture as output.

sorry didnt realize about the signature thing.. i filled that in. but my main Isadora computer is:
MAC PRO 2012 5,1 12 CORE XEON 3.46GHZ, 64G RAM
RADEON 5770, PCIE USB3, PCIE ESATA, PCIE SSD
MAC OS 10.13.6 , ISADORA 3.0.7
Yes the 2013 MacBook Pro laptop I tested all works fine with the same Kinect, isadora, OS and plugins.
yes it did seem to work fine on the mac pro for 2 days before the guru session happened. i even tested a backup of my OS on a different physical drive from 3 weeks ago..before I did the ITUNES update that broke 32 bit, and the kinect didn't work on that either..But then I restored the mobileframework on my current OS drive in /private frameworks and got 32 bit apps working again. i would be willing to try anything at this point.. so please send me the the homebrew info you are suggesting. thanks
Today so far first bootup of the day the kinect was working.. only for about 2 min again. and then data and depth image freeze. this time was able to get it reconnected with only restarting isadora not even unplugging the camera. now then got it working for about 10 min.. but the depth image is a bit choppy.. only running 15% load on isaodra. then it froze again. So far In my testing every time i actually get it recognized the image and data freeze up soon after. Also Im NOT having the power light on the kinect stop blinking no matter what USB port I try so seems like the power bug went away.. and I haven't done anything different today.. still currently testing with Open NI 096.. would you consider that the most reliable version or is 092? i dont need to record feature right now.
p.s. also test delicode ni mate v2.14 and the app wont even open, it was the only and i think latest version avilable on their site.
I've attached a screenshot of the details you asked for plus the information I am getting From the Isadora Open NI Tracker Beta.
I'm using Isadora 3.0.7.
I'm have a 1414 Kinect Xbox 360 and have also downloaded the KinectSDK. Doesn't seem to help sadly.
It seems that it is somehow finding the Kinect because the 'sensor uri' output shows a meaningful value. The skeleton tracking is disabled however, which indicates the tracking component refused to load.
Try turning the 'use callbacks' input off. Does it change anything?
What if you turn 'body tracking' input off? Do you see the depth map image then?

@mark I sent the results, check your messages.
No hurry though, because your reply here was enough to help me solve the problem.
play time :)
@mark I have deleted the kinect f0r windows sdk 2.0 and installed 1.8 as somewhere i read that 1414 kinect only works with sdk 1.8. I now have an image! :-)
So is anyone having good results with the kinect v2? i may get one if it works more consistently than the v1
@mark I have done much more testing and I really want to get this working. I had some good results with my laptop which is on mac os 10.13.6 (17G65), so i figured I'll just clone that boot drive and see if the mac pro has better results seeing the kinect like the laptop is.. I did a couple tests, first 2 times worked right away but then all of a sudden 9 out of 10 attempts fail.. this is making not much sense any more. Further.. even my laptop which sees the kinect every time fails the simple viewer test script?? what gives? I have tested 3 different builds of 10.13.6 and 10.12 on my mac pro and can not get the simple viewer script working or the kinect to reliably connect to Open NI tracker. I can get it to see the kinect about 1 in 10 trys but then it always freezes within 5 min.
I have done much more testing and I really want to get this working.
I am doing all I can on this topic, but I am overwhelmed with numerous urgent tasks that require my attention and cannot devote more time to OpenNI Tracker until this coming weekend. You will simply have to be patient.
In general, you seem to be the only one experiencing these problems and I am concerned that there is simply a problem with the older Mac Pro, and I will not be able to debug it because I do not have a machine like that.
I would not be concerned about the test program. If the OpenNI Tracker works well on your laptop, then I would suggest using your laptop.
I will try to come back later today with the instructions on how to compile your own libusb on the older Mac Pro. Maybe that will help.
That is what I can offer at the moment.

Everything is working like clockwork with my Kinnect and I have been piecing together interesting new scenes using Marks scenes as starting points. This seems to be the best way for me to become fluent in new pieces of the platform. Unless I put a motion blur actor on it the skeleton shows up as a shadow when I use the Kinnect as a Mask. The other question I have is whether the particles can be combined with an alpha mask somehow to created a way of wiping through one layer of video into one below it. THANKS FOR ALL YOU DO!! I'm using a Kinnect 1414 if anyone is looking for suggestions about what works in the Kinnect department

Here are the instructions for homebrew.
1) Open a Apple's Terminal program (/Applications/Utilities)
2) Install the Xcode command line tools. Enter this command and hit return.
As indicated in these detailed instructions, a dialog will appear asking you to install the command line tools. Follow the prompts and install them.
3) Install homebrew. Enter this command and hit return.
Detailed instructions can be found here.
/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install.sh)"
It will take some time for this to complete.
4) Compile libusb on your machine. Enter this command and hit return
brew install libusb
This also may take some time.
5) Finally you need to get the compiled libusb. Type this command and hit return
This will open a Finder window and you should see libsusb-1.0.0.dylib.
Note: if the version number of libusb changes, then the command above will not work. To find out what that new version number is, enter the two following commands
cd /usr/local/Cellar/libusb ls -al
You will see the version number of libusb listed in the result -- in this case 1.0.24. You would use this number instead of 1.0.23 in the command above.
drwxr-xr-x 3 xxxxxxxx staff 102 Mar 29 14:38 . drwx------ 41 xxxxxxxx staff 1394 May 7 15:51 .. drwxr-xr-x 12 xxxxxxxx staff 408 Mar 29 14:34 1.0.24
6) With the finder window of the compiled libusb open, you now need to open a Finder window for the OpenNI Drivers in the OpenNI Tracker plugin. Enter this command and hit return
open /Library/Application\ Support/TroikaTronix/IsadoraPlugins_x64/OpenNI\ Tracker.izzyplug/Contents/Frameworks/OpenNI2/Drivers/
7) Now drag the libsusb-1.0.0.dylib from the lib folder to the Drivers folder.
And choose to replace the existing libusb
8) You now have a libusb custom built for your hardware inside of OpenNI Tracker. You can reboot Isadora and see if it improves the situation for you.
So please follow these instructions and see how it works out for you.
@mark thanks so much for your help i know you are doing a million things.. I will try a different type of camera if this doesn't work solidly for me.
is the orbbec astra the best most solid option?.. curious to hear form other users which camera they find to be the best overall. thanks everyone.
