In the tutorial ( Ari Danesh - Next Steps MO6 ) at the 15:20 minute mark Ari is showing how to use the Break SOP.
I am having problems getting it to work.
One of the first things he does is with the break sop placed down is set selection to primitives and then enable the select tool.
Then he places the cursor over the face of the front side of the top half of the box that is going to be moved and saying “…select one of these primitives and hit the zero key to select all…”
He then hits the t key from which he grabs the top handle and moves the newly separated top half from the bottom half. ( Screen Shot “A” )
First problem for me is that hitting the zero key does nothing. Now I noticed that he is using a Mac and so I went into help to try and find an equivalent perhaps because I am on Windows. The only thing that I found close is that there is the n key for selecting all. However, this doesn't work for me in the sense it selects everything in both top and bottom halves of the break.
So as an alternative I did a combination of shift + clicks for all 4 sides of the top half and top.
but when I go do the transform it moves those selections but still maintains a connection to the bottom creating a mesh between the two. ( See my “B” screenshot ).
So in attempt to try different things I unchecked “create inside surfaces” of the break SOP.
When I do that it creates a clean break between the top and bottom half, but it doesn't create face where the break was made and so am left with an open shell.
( See my “C” screenshot ).
I am at a lost, after trying many different “settings” looking through my UI and reading the help file on the break SOP to know what to do to get it work.
Any help is much appreciated.

Houdini Learning Materials » Compressing Channels with Key Frames

Hello,
Working on the Ari tutorial with Key Frames ( first steps video - M4 ).
When he brings up Global Animations window to make changes to the number of frames and clicks on apply he is given an option of whether or not to compress channels.
When I do the same I don't get this option ( compress channels ). I don't need to do this at the moment since I am only just following the tutorial.
But I am curious if this option was removed since the same intent can be accomplished in a different way or maybe I have some preference settings that may be different somewhere else?
Thanks

Thanks danBode for that tip….
I switched that on; looks good and blends well with the rest of the UI, at the same time it's quicker than looking to read the type of the tab to figure out which level I am at.

ok so it does….
what happened is that I had a sphere and was in that sphere…deleted the sphere but didn't realize I had only deleted its sub-node.
So in that case geometry node is not available at that level.
going up one level to actually delete the whole sphere solved the problem.
sorry for creating any confusion.

It's not in mine.
I use to TAB and begin typing Geo…. and then be able to get it.
But no longer.
I TABed and looked under ALL and it's not listed, which is why I thought it may be under a different name.

Hello,
I was working on an Ari tutorial with Houdini 14 a couple weeks ago.
Installed H.15 and wanted to go through the same tutorial again but it calls for dropping down a Geometry Node of which I cannot see/find in Houdini 15.
Is there an equivalent to a Geometry node or is it now under a new name?
Thanks

Thanks for this suggestion,
however when I try to open the duplicate file I get an error message saying “invalid .hip file header”.
I may not be able to get to this forum for a couple days so I appreciate the attempt in responding. I think I may just have to start from scratch.
I have a feeling that the way I have my project folders set up is creating problems too, so I will ask questions about that when I get back and try the tutorial again; The review will be good anyways.

When we save to create a digital asset does some information become embedded in the *hipnc file that we create the digital asset from?
The reason I ask is that I was doing the Ari Danesh hose tutorial and got all the controls working fine then at the end right clicked on the object to create the digital asset.
In the process I tried saving the asset under a different name other than the default that was going to be used in the create digital asset dialog box and change the location.
Somehow in the whole process some errors came up and in an attempt to start creating the asset from scratch again I deleted any files that where in the destination folder I tried to save too.
I did not delete any files from my Project Folder from where I made the *hipnc file.
However when I open up the *hipnc file in my project, everything works fine as originally intended and created but the object that I attempted to create the digital asset from now carries an “error border” around it saying it has an incomplete asset definition.
This is why I think something is now embedded in the *hipnc file because I can still “use” it as before but I want to get rid of this error flag without having to start the project from scratch.
Any help is appreciated.

Houdini Indie and Apprentice » ALT+E not working?
- BabaJ

Hi,
I'm working through Ari Daneshs' first steps tutorials, and in video 3 he opens up the “Open Editor” with Alt+E.
This hotkey doesn't work for me however.
In this tutorial he's working on a file SOP expression, opening up the editor with ALT+E; And if I right click on the text box of “Geometry File” of the file SOP I can find the editor and bring it up under “Expression” from the list from right clicking. So getting the editor up is not a problem.
However, I can't get it through ALT+E.
When I open the Hotkey Manager it lists “Open Editor” as having ALT+E assigned to it.
So this seems like a bug, but I don't want to report it in the bugs section because I am still relatively a very new user of Houdini and it's possible there is something I am not doing right or understanding.
Any feedback on this issue is appreciated.
Thanks

Houdini Learning Materials » How to Assign Position to a Group of Selected Points

Thank you very much SreckoM and tamte,
Both methods work great, will have to keep this little tut from you guys in my ‘learn’ folders for future reference.
For any other newbies reading through this post with interest, just a couple notes that might help you if you ran into any troubles like I did trying SreckoM and tamtes' suggestions:
for that google gif doc I downloaded a gif viewer that helps you stop to make sure you don't miss what's being done;
http://sourceforge.net/projects/gifviewer/?source=typ_redirect [sourceforge.net]
When following SreckoMs' gif I ran into problems when doing the TAB to bring up a point network node:
You have to have the mouse cursor in the scene window pane and not in the network window. Both ways will create a point node for you but the selected points will not get entered automatically in the Group textbox of the point node parameter window if you create a point node from the network pane.
Also, make sure you are in wireframe view and not any solid mode as doing so will only select the points that you can see and not also the ones behind them.
Thanks again guys for your help.

Hello,
I've worked through the beginner tutorials and am now working through the Ari Danesh tutorials “First Steps”.
In the second video of that series he is working on modelling a tea candle holder.
A sphere is dropped down in scene and a side view is set.
To give the appearance of a flat bottom on the sphere the bottom two rows of points are selected and through scaling and translation are put roughly at the same level as the bottom third row of points.
I understand the point of the exercise is not to give “precise” object models but I was wondering how I might be able to place the points more precisely. I come from a SolidWorks background where I am used to designing objects with precise constraints. I understand the purpose of Houdini as a whole is a totally different application but nonetheless my curiosity has been perked in this tutorial.
So as an exercise and opportunity to explore Houdini a bit more I was wondering how I might be able to make that bottom perfectly flat, or rather getting the bottom two rows Y point value positions to match to the bottom of the third rows Y point positions; Within the existing model of this sphere, save building a model from scratch in a different way, or using other Poly Tools, etc.
I found that if I only select one row and through the use of spreadsheets compare the different y values a simple translation of the y axis will suffice from the subtraction of the two values.
But I can't do that with both rows selected at the same time.
The closest I've come to what I think might work is using a PointWrangle.
When I drop one down into my network and select my two rows of points and select that group in the Pointwrangle drop down menu and as expected the numbered points ( that I saw when working with spreadsheets ) get input into the textbox suggesting to me I am on track.
The wrangle also has setting for “Group Type” and “Runover” of which I set to “Points” assuming this is what it should be.
I also am assuming that in the Vex Code textbox is where I need to put the code for what I wish to accomplish.
But alas I have tried ( with my limited use of working with Houdini code ) entering different equations of which none have worked so far.
It would be much appreciated if anyone could offer insight on what code I could use, node type in network to utilize or combination of the two to manipulate specific selected points of an object.
Thank you

In the 4th video of this tutorial project there is building a series of elements in the Network to get the first Spot as in the Screen shot below from the tutorial.
However, for some reason I cannot get this spot to appear.
I have gone over the tutorial three times to double check that I have done the same as the tutorial plus playing around with controls that the tutorial puts in the project that can adjust parameters.
I have also done extra things like closing and reopening the project, window panes etc. in case my problem is just some video glitch.
But I haven't had any success in finding a solution.
If anyone can suggest some things to try or what part of the tutorial to take another look at it would be much appreciated.
Thanks

Just wanted to get back to your earlier post.
Yes when I was doing the tutorial I had the flags set correctly ( I tried switching them on and off to get it to work ).
I didn't check the “Ghost other objects” drop down menu at the time but by default it is set at “Ghost other objects” when I open a project and which is how it was and not altered for the tutorial project.
When I restarted the tutorial from scratch the next day, for some reason it did work this time even though the “Ghost other objects” was on.
So perhaps I unknowingly I did do something being new to this program but time will tell if it's something else the longer I use this program.
Thanks again for helping with your feedback.

Hi,
Thanks for taking the time to respond.
As the afternoon went on I continued with the tutorial but was so focused with learning to understand I forgot to do saves.
And because I think I messed up how to set up a Project ( where files are saved to ) when I set the project and opened the working file it seemed to be missing what I should have.
So tomorrow I will be restarting the project from scratch again as going over all the elements of the tutorial will be useful.
But when I get to the same part I originally posted about I will review what you have suggested and post here again.
Thanks Again

Hello,
Working through the SpiroToy Lesson and have come across a difference in output compared to the tutorial.
At the 23'30“ point in the tutorial the instructor is running the animation while at a certain ”Navigator level“ ( Excuse me if my terminology is not correct - still fairly new to Houdini; I have included a screen shot of where I am that shows the same as the tutorial ) for the wrangler object.
While the animation is running he is adjusting the parameters of the wrangler object ”on the fly“ so he can see the immediate result of the changes save of course a restart of the animation sequence.
The problem is that although I have been following his example to a ”T“ at this point in the tutorial when I do the animation it only shows the object moving but not the effects. The only way for me to show the effects is to go up/down in the navigator to show the ”nodes" in a different format in order to see the animation affects also when running the animation.
This is probably just a bit of nit picking but I just want to learn the ins and outs of this program and I suspect there is some setting somewhere that is different than the instructors but can't figure it out.
Any help is much appreciated.

Hello,
Going through the Workspace tutorial there is a part in which the offset is put at a value of 0 and at another frame of the animation it is set for 0.5. Working around manually I managed to get it working but not how it was done in the tutorial.
In the tutorial it seems like the offset box is highlighted and in the video it is briefly flash showing “ALT” and picture of left mouse button.
The offset has 3 text input boxes beside it and in the video after showing alt and mouse it appears the mouse cursor is being dragged to change the values of all 3 text edit boxes at the same time.
I'm just trying to get the same functionality, maybe its because I need to change some preference setting?
Using alt and left mouse button doesn't do anything for me.
Thanks to anyone who could help.
