Hello,
I was reading the Vellum Constraints geometry node docs and have found a Shape Match constraint but can not find it in the vellum constraint type. does any one knows where to find it?

it was added in 18.5.472, so make sure you are running at least that build
https://www.sidefx.com/changelog/
Houdini 18.5.472 The Vellum Solver has a new Shape Match constraint type, which can be added to existing Vellum constraints like cloth to make objects more rigid, or be used on its own. The Vellum Constraints SOP can create these constraint types, with the typical Define Piece parameters controlling which points go into each object. NOTE: these constraints have the same NVIDIA driver requirements as Pressure constraints, as specified in the What's New Vellum section of the help.

you can download the daily builds and run it with apprentice licencing (aka the learning edition) fine.

Do you need any special driver for the shape match mode?
from the docs (I assume newer versions will also be fine):
https://www.sidefx.com/docs/houdini/news/19/vellum.html
Shape match constraints require the latest driver for NVIDIA Ampere series cards. This is version 456.38 on Windows [www.nvidia.com] and version 450.80.02 on Linux [www.nvidia.com].
If you don’t update your driver, you can alternatively set the following environment variable to disable this feature: HOUDINI_OCL_FEATURE_DISABLE=CL_DEVICE_DEVICE_ENQUEUE_SUPPORT. For more information, see environment variables. [www.sidefx.com]

I have the same problem, with houdini 19.0.498 or 19.0.531
NVidia driver GeForce 511.79 and also with Nvidia Stidio 511.65 I was working on mardini stuff and the geometry just disappears at the second frame.
CPU: i7 3770K, GTX 1080 ti, 32 GB ram
I think then is because is not an RTX card :[
UPDATED...
It seems to works disabling it with:
