OpenNI for Orbbec Astra

[jib]

Hi there,
I’ve fllowed installation steps from this contribution but can not get it working. The nodes are not red but the camera does not start and there’s no texture output. When I tried to connect Preview (DX11.Texture) Inside TTY renderer I got message :

00:00:43 ERR : Exception caused by node during update :/73/1/16
00:00:43 ERR : Exception node name :RGB (Openni2 Openni2)

At the same time with Gamma nuget it works properly so I presume its not a driver problem…
What do I miss here ??

vvvv version : beta 42
camera : Orbbec Astra Pro

Thanks !

Hi there! I guess something changed within the latest dx11 pack which causes the error. This contrib is no longer maintained. sorry

@schlonzo I see, what a pity !
Anyway I think I solved it by ignoring the last two installation steps. So what I did is :

1. Extract the contribution’s openni folder into the dx11 pack plugin folder (…\packs\dx11\nodes\plugins)
2. Download DX11 and DX11 Particles packs
3. Download & install the Orbbec Astra driver https://orbbec3d.com/develop/ (tested with v 4.3.0.17)
4. Install OpenNI https://structure.io/openni (tested with v2.2.0.33 Beta)
