I asked last year about this issue and got this response.
RFE #160907
Hello Alexander,
Many released back (well before Houdini 20.0), or development team made the decision that Houdini help files will not launch from the external web browser.
You can open these help files from the internal browser, inside of Houdini. And launch the files directly from houdini/help/examples

I think you have changed the definition of this node. The easiest solution would be to backup the houdini20.5 folder in your home user directory and start Houdini again.

Hi,
many reasons can be for this behaviour but can you create a node using Python?

An easy way to do this:
upadate:
upadate:
float pos[]; int grp[] = expandpointgroup(0, "endPts"); foreach(int pt; grp){ push(pos, vector(point(0, "P", pt)).y); } float result[] = sort(pos); int pts[] = argsort(pos)[-2:];

Hi,
Here's a good explanation of how to get it.

This tool appeared earlier than other schemas and if you open the source code directly in the toolbar you can see how it adds these schemas.
self.mySchemeMenu.addItem("Light", "config/3DSceneColors.light") self.mySchemeMenu.addItem("Dark", "config/3DSceneColors.dark") self.mySchemeMenu.addItem("Grey", "config/3DSceneColors.bw")

Hi Alex,
I can't seem to use that command. I've tried it in the Python Shell and the Python Source Editor, nothing happens.
It should work. Try opening the Python Panel additionally.

Hi,
1) A workaround for this could be to use a module that loads examples from the help.
2) I've thought about this too but there doesn't seem to be a way to add new colour schemes.

ObeidaZakzakYes, but the string "20.5.429" doesn't work as a variable for
The expression syntaxe actually expects string values.

To activate the tool you need to select a node, move the cursor in the viewport and press Enter.

I think this is because a number is expected, not a string. But there is a problem here that the value is only read up to the first dot. So it only works for non-string comparisons.

I'm not sure, but the filter using attribute (@) binding for vertices doesn't work in the table for some reason, although it works for points and primitives. It's probably a known bug.

You can do it this way:
or
// 0.000000000135 -> 135 // 0.456 -> 456 // 0.0000567 -> 567 // 0.01 -> 1 float input = 0.01; float value = input * pow(10, abs(ceil(log10(input)))); int n = -1; float eps = 1e-9; while(value - floor(value) >= eps) { value *= 10; ++n; } int result = int(value);
or
float input = 0.01; float value = input * pow(10, abs(ceil(log10(input)))); int result = select(value < 1.0, atoi(sprintf("%g", value)[2:]), int(value));

The irony is that this node only uses VEX for this purpose. 
If you really need it you can make it visible again for the SOP context using Texport:
The recommended way now is to use Labs Group by Attribute to do this.

opunhide Sop labs::group_by_color
