Fabricio ,
The Attribute Promote help page has approx 15 examples you can load. Hopefully you might find something within the examples to inspires a solution.

But, you get those options with the promote attribute sop.

Also noises have specific output ranges, they come in the documentation, so you can always add a fit node to change your range to what you need, in the geometry spreadsheet you can also sort by value so you can see max and min. If you press X with your mouse over the noise output it will add a visualization node, you can visualize on the viewport or in the geometry spreadsheet the values. I know its not the same but as far as I know their is no way to do the same as the get maximum in set node in a vopsop context.

The ramp parameter kind of works but as you say, is not that user friendly and does not show the points below 0. (that's ok, but I wonder if it is possible to write a custom widget in houdini) anyway, the thing I could not get right just yet is that sort of "get maximum in set" thing. Sorry for using ICE language, I'm trying to be open minded here, so please tell me if that`s not the correct mindset. so on this graph: ...how could I get the maximum value of the output noise node and compare to a single point output of the same node? >From what I can tell, I'd have to: 1- create this pointvop node with a turbnoise, then store the output noise into an attribute (via bindexport?) 2- up one level -> drop an attrib promote (detail), set to maximum 3- drop another pointvop node with another noise node inside (same parameters) and compare the result noise to that found on the atrib promote node?? I'm 99% sure this is totally wrong...how would you go about that single task specifically? and finally, thanks for the suggestions on houdini forums and discord. will try both (although I pretty much like this list =) ) 2017-03-06 15:17 GMT+01:00 gareth bell <[email protected] <javascript:_e(%7B%7D,'cvml','[email protected]');> >: yeah - the lack of handles is frustrating _____ From: <javascript:_e(%7B%7D,'cvml','[email protected]');> [email protected] < <javascript:_e(%7B%7D,'cvml','[email protected]');> [email protected]> on behalf of Olivier Jeannel < <javascript:_e(%7B%7D,'cvml','[email protected]');> [email protected]> Sent: 06 March 2017 14:05:17 To: Official Softimage Users Mailing List. <https://groups.google.com/forum/#!forum/xsi_list> https://groups.google.com/forum/#!forum/xsi_list Subject: Re: houdini question (and where to ask) yep but it has no handles and try to make négative values, it takes them but wont show on the curve as it has a 0,1 space.

Ramp Parameters is sort of fcurve. It's a bit weak in terms of curve manipulation, but does the job. It has 2 modes rgb (ramp) and spline. If you use several ramps in the same vop, name them with different name or they might not export.

Question #1: are there any equivalents to ICE "get ... in set"? or or do I have to iterate and store values for later comparision? In other words: what is the best or recommended workflow to compare single point data with global point data? Question #2: any nodes that resemble a fCurve node, like we have in ICE? if not, what is the alternative? and finally, I can see this list is becoming more and more houdini-esque than ever..but, what is the best place to ask beginner questions like the above? houdini foruns, houdini list, odForce... thanks! 2017-03-06 14:23 GMT+01:00 Fabricio Chamon <[email protected] <javascript:_e(%7B%7D,'cvml','[email protected]');> >: Hi, I'm slowly getting into houdini and this is my first attempt to port a really simple ridged fractal deformer made in ICE to houdini (using pointvop).
