Cannot start here the Nodes from VL.Device.RealSense.
They have problems with Stable2021.3 and Preview2021.4 but working with Stable2020.2.
I’m using a RealSenseDepthCamera D435

did you use latest preview version?

Sorry I forgot to mention it.
I tired it with
no sucess with with Stable2021.3 and Preview2021.4

ok, thanks for the report.

Not good that it ran in 2020.2 but not in 2021.3 anymore. However there was an easy workaround in the library itself contained in a new preview package (1.3.1-alpha) you can install with nuget install VL.Devices.RealSense -pre

Upcoming vvvv gamma builds (>= 2021.3.1-0087) will contain the proper fix.

It does now what it should
