In asset Type Properties->Basic I can see field Maximum Outputs which is set to 1 and disabled.
Also I read somewhere in the forum that Houdini 14 has possibility to set more than one output in hda.
So, is it possible?

Houdini Indie and Apprentice » How to avoid constrained points shift in soft body?

For example in attached scene cube is made into soft body and grid - in static object. Then one face of cube is attached to the grid via Cloth Attach Constraint. If you run simulation you can see how cube face (and whole cube with it) moves to the grid. It is undesirable in many cases. How to make it so that constrained points don’t move to the target surface? I.e. they should be as if they were attached to the grid via hard rods.

Houdini Indie and Apprentice » How to use sop groups in dop networks? [Solved]
- Илья Фивейский

For example, when I use ‘Cloth Attach Constraint’ node I should set ‘Constrained Points’ parameter in this node. I can do it via ‘Attach to Body’ tool selecting points manually. But what if it is necessary to use procedurally defined group for this ‘Constrained Points’ parameter? For example it can be surface boundary. In general such group can’t be defined manually because surface topology can change.
I tried to use expression
' '.join()
in the ‘Constrained Points’ parameter of the node in attached sample file. But it doesn’t work. I get error:
Also I tried groupbyval HScript function (though not in the sample file). It returns some crazy string with negative and huge numbers. I guess it is a bug.
Any ideas? I mean - is there another method to use sop groups in dops? And where am I wrong in my expression?
P.S. There is attached sample file where above mentioned expression is used. It is very simple - just two cubes, soft body cube attached to the static one. So you can try it.
EDIT.
Well, it appears to be trivial - just set the parameter to the corresponding group name. Somehow I thought that it is not possible a priori. Maybe because there is no drop-down list for groups as in sops.

It works now. Thanks.

Well, this 2.6.8 version, in fact I installed it in /usr/local from sources trying to force Houdini to use 2.6 version. It did not and continued to use 2.7 and crashed as it was before installing 2.6 version. So I set HOUDINI_PYTHON_VERSION = 2.5 and it helped (I didn't realize that I can use HOUDINI_USE_HFS_PYTHON then).

New error in attachment.
Houdini version 12.5.501.
I have python 2.7.4 (but not older versions) installed and set HOUDINI_PYTHON_VERSION = 2.5 in order to run Houdini (otherwise it tries to use python 2.7.4 and crashes).
