Why User (Kinect OpenNI) texture output is black in raw mode?

Hi.

I use User (Kinect OpenNI) module in raw mode, and Depth (Kinect OpenNI)in raw mode too.
So Depth works correct, but User module gives only black texture and center of mass and ID per user. When i change mode to viewable, i can see correct siluete.
In same time Depth texture is correct in both modes.

What i’m doing wrong?
Why i don’t have texture in raw mode?

vvvv v4.28.1

in raw mode the texture is not supposed to be human visible. it only sets a value of 1 to a pixel with user 1 and a value of 2 with user 2. so this is for being used in further processing with a shader only.
