Stereoscopy + DLP Projector

Hi, I’m trying to crate a stereoscopic projection with DLP projector and active shutter glasses using a 3D scene of TD.

My pc have a graphic card nVidia Quadro M2000M and I have load the preset “3D OpenGL Stereo” so now the Stereo 3D is enabled.
I have a BENQ DLP projector connected via HDMI and set with a resolution of 1280x720 120Hz.
I have also enabled the “Sync 3D -DLP Link”

I’m not able to correctly configure TD to use “OpenGL_Stereo”.
derivative.ca/wiki088/index. … nGL_Stereo

Using the example of this page the stereowindow show an error:
“stereo was not properly setup. Ensure the TOUCH_STEREO=1 environement vaiable is set.”

From Dialogs->Variables/Macros #Variables->Root I have added the correct value and saved.

But the stereowindow show the same error and the windows doesn’t show a flux of synched image alternating left and right render.

Anybody use this procedure to create Stereo Visualization?
There is some other way?

Hey,
The environment variable needs to be set in Windows, not inside of TouchDesigner. Moving this topic to the General forum since this forum isn’t for questions.
Let us know if that helps.
