Thank you very much Tomas. I followed your instructions (with the HDA Type Properties opened) and there was one small issue with the promoted Transform Handle. When entering the Pivot Mode (working with the HDA transform handle), the gizmo stayed in the "transform mode" and did not update the Pivot parameters. So I repeated the promotion steps with the internal Transform SOP and with its Pivot Mode Handle and both handles seem to be working fine.
Should I RFE it? Or is it correct to promote each handle (xform + pivot) separately?

I have tried to investigate the dependencies of the internal Vellum solver, but clicking solver's References freezes Houdini (and crashes after tens of minutes). I have also tried to Timeshift Inputs and Outputs of the Vellum solver, but the cook still simulates up to the current frame.

Please, Guide Groom SOP is recooking the internal Vellum solver on many occasions. Sometimes, when I delete some downstream node, sometimes when I dive into the network... but certainly the recooks seems unnecessary.
- I don't have time dependent geometry
- it "simulates" to the current frame, which is tedious
Is it normal? Can I disable it somehow?

Thank you very much Geoff. I attach my attempt to test the impact of the Parting Line. It works exactly as you described it!
Btw it is pity that we cannot use Guide Groom tools to affect Parting Lines. The Brush tool, the Sculpt tool... I have tried to temporarily disable the @group_partinglines, but then the parting line's "root" snaps to the surface (obviously).
Thanks again! Best regards.

This expression function kind of works, but there need to be nodes connected to the referenced node ("outside"). And the indexing counts only the connected nodes:
In the attached image, the index 1 is the node "B"
`opoutputpath("/obj/geo/vellumsolver", 1)`
In the attached image, the index 1 is the node "B"

Lets say I have a node with more outputs:
/obj/geo/vellumsolver
Isn't there an "universal" syntax to reference the second output? For example to Object Merge SOP the Constraint geometry?
/obj/geo/vellumsolver:2?
Do I have to know the exact name of the internal Output node?
/obj/geo/vellumsolver/output2
/obj/geo/vellumsolver

I am beginner in Houdini Grooming and would be grateful for an example of use of the Parting Lines. The toggle "Respect Parting Lines" promising "a brush will only affect guides on the cursor’s side of a parting line" on the Guide Groom SOP is really tempting. I was hoping, that if I start the stroke on one side of the parting line (or "inside" parting lines?), then the brush will not be affecting the guides on the other side of the Parting Line.

I went through the masterclasses for H16 and H16.5 and everything (except for the new Guide Groom) seems to be valid in H20.
I also went through the docs of the following nodes and majority of them are "Since 16.0" or "Since 16.5" and all the principles seem to be valid for H20:
Fur
Groom Blend
Groom Fetch
Groom Pack
Groom Switch
Groom Unpack
Guide Advect
Guide Collide With VDB
Guide Deform
Guide Draw
Guide Groom
Guide Group
Guide Grow to Surface
Guide Initialize
Guide Interpolation Mesh
Guide Mask
Guide Partition
Guide Process
Guide Skin Attribute Lookup
Guide Tangent Space
Guide Transfer
Hair Card Generate
Hair Clump
Hair Generate
Hair Growth Field
Reguide
Wire Blend

I have found this comparison, it shows the difference between the old and new Guide Groom SOP:

Please, are the other nodes and principles (from the 16.5 Masterclass) still valid?
(BTW in the video, Andrew points out, that he misses the "Cut" mode in H19, and adds that in 19.0.541 SideFX have added the Cut mode. It is available in H20, too.)

Please, I am a Grooming beginner. Should I watch this tutorial?
https://vimeo.com/241572150 [vimeo.com]
I would like to understand procedural principles. There are quite a lot of Grooming nodes available, and I am not sure, which are obsolete. There is no new Grooming masterclass, unfortunately, and H19 brought this:
"Completely redesigned grooming toolset with many new tools, and interactive brushes."

Please, how could I set the FFMPEG to premultiply (and bake) Alpha channel into .mp4 properly? An example and my settings are in the attachment.
The .mp4 is meant to be a preview of the sequence (I don't expect the .mp4 to contain an Alpha channel)

The VEX function setpointattrib() does not set the autobound attribute.
It seems, that I have to create two wrangles? One wrangle for floats and second wrangle for vectors? And Switch SOP between them with a pointattribsize() expression function?

Please, I am creating an HDA:
- user can set the name of an Attribute
- HDA calculates a float multiplier and multiplies the value of that Attribute
- the attribute could be float @Alpha or @pscale, @radius, @width...
- the attribute could be vector @Cd
It seems, that attribsize() does not see the autobound attribute.
Please, what would be the preferred (or fastest to cook) way to create such binding?
