Hi!

I'm using bind export in Point VOP to create an attribute to copy stamp. I can see my attribute name and value in the geometry spreadsheet, but I haven't found any way to access these for copy stamping.

After some research I found that point expression can be used to do this. But I have no idea how. http://www.sidefx.com/docs/houdini14.0/expressions/point [www.sidefx.com]

The Point VOP is a noise. Ideally the attribute should be driven by a ramp too. This is what I'm after, sort of:



Any help is appreciated!!!

Best,

Try this. This uses a foreach loop/compile with a spare input for speed. In this trivial case, there is no great difference between doing this and doing the old copy/stamp way, but if you had a lot of points this would be much faster.

See this for an explanation: http://www.sidefx.com/docs/houdini/copy/tutorial_stamping.html [www.sidefx.com]

Thanks Mr. Catfish! I'll definitely take a look at that explanation!

By the way, is there a way to add a ramp to this parameter in the Copy Stamp SOP? :



I tried creating a chramp in an attribute wrangle and feed that attribute as a parameter, but to no avail.

I solved the issue with adding a ramp to the copy stamp variable.

I just attribute wrangle:d a chramp over @ptnum/@numpt. Very easy. Works like a charm.
