About Notch Blocks NVIDIA AR Broadcast to touchdesigner

I have already copy the Demolition-NGXCUDA.dll

to C:\Program Files\Derivative\TouchDesigner\bin

But Touchdesigner seem didn’t get the NVIDIA AR Broadcast running , Is anything I do wrong?



Unfortunately there’s a known conflict between the version of Nvidia AR that Notch is using and the one that ships with TouchDesigner. This means that when you run a Notch block inside TouchDesigner it tries to load TouchDesigner’s Nvidia AR instead of the version it is expecting.

You can work around this for the moment by also copying the ‘nvARPose.dll’ and ‘nvinfer.dll’ files from the Nvidia AR SDK into the TouchDesigner/bin folder. This will break TouchDesigner’s native FaceTrack CHOP, but should allow you to use the version in your Notch block.

Hope that helps. Let us know if you’re still having problems.

Thanks @robmc
the way fix my first problem!

but in Touchdesigner it broke the NVIDIA Background function
I use Notch to do the NVIDIA Virtual Background effects export blocks to Touchdesigner
also can’t work to

how to fix it ?

hmm, that’s a tough one unfortunately because the two nvidia modules require different versions of the nvinfer.dll library. I’ll try a few experiments here to see if I can find a way to make them all work together and will let you know.
