This one came out of the blue. I was editing UV points in SOP UV Viewport, using UVEdit Op. It was working fine, then badda-bing-badda-boom, out of the blue, the Handle Group x-form gizmo stops working. It no longer transforms the UV points. The ‘Handle Group Follows’ got turned OFF. I turn in back on in properties, but as soon as I try to move a multiple UV points, it stops working. The option ‘Handle Group Follows’ gets turned off automatically, as soon as I drag the handle, it moves but selected points do not. So I am reduced to moving UV points one by one or using Properties Panel.
You can only imagine my frustration. I don't know what I did to make it so. It just happened by itself. It was working then simply stopped. Houdini is a PIA to learn.
I am not enjoying the proccess at all.

OK, I think that did it. THX a lot. But you gotta admit, that these kind of problems just makes learning a more painfull proccess.
I have another question. I wanted to try out Bezier modeling tool. So I decoded to model a simple character.
I renamed Geo1 to ‘Froogy’
In SOP I created a Bezier sphere, with 8X8. Then using Edit, I reshaped the head to add ears and eyesocket bulges. Nothing pro looking, just want to get a feel for the modeling tools. I am 1st and foremost a 3d modeler. My usual tools are Rhino, formZ,and some Maya. I am a wiz with subdivs, and can create almost any hard surface model with NURBS. My URL is below.
I then created a new bezier curve OP for the body , in same Froggy model. Revolved with Revolve Op followed up with Edit op to sculpt the body. So now I have two 3d surfaces, both bezier, in the same model. I merged them together with Merge Op.
Me question, to which I cannot find the answer on CD_ROM. How do I add points, insert column or row of points to a Bezier surface? The PolySplit only works on polygon objects. Edge Divide Op does seem to work on Beziers. Which SOP am I looking for?
Edit Op, as far as I can figure, is used only for pulling and pushing of points. See I think that it should be allowed to use any of the modeling ops under Edit and not have be remembered. I understand the reasoning for proceduralism, but in some cases thats taking it too far. I see no need to have the app remember thousands of modeling operations where I refine the surface, and sculpt it.

>Please try this:

Pane Window| In the Courseware and in product demo, it was clearly shown that when a pane is divided the new pane can display whatever information that I wish (Viewer, Network, Graph, etc..) So I say again. When I divide the panes the new panes CANNOT be changed. The button that rolls out the options for the pane display is inactive. The original panes, that were present when Houdini starts, can be changed just fine. The new ones cannot. Pressing down on that button in new panes does not bring up the options. Its simple as that.
Another problem that just crept. But its not consistent. Lets say I animate a channell. It animates in Viewer, the colors all get highlighted in properties in OBJECTS. But if I SCOPE that channell, the graph is not there. Fitting the window to graph does not display it. Even wierder there is no information in the Dope Sheet or Table. But the object is animated. I do make sure that Graph is scoped on the correct channel, but there is not graph. The viewer linking on all panes is set to (1). SO WHATS UP WITH THAT? This app is weird. It is not at all intuitive. Its quite confusing and unpredictable.
Here is another circumstance of above.
I animate a sphere moving up/down. Only the Ty channell has a graph. And initially I can scope it and edit it. Then I change DESKTOP to another layout, and make sure that all panes are linked. After changing desktop, I cannot at all scope that channell. The channell is brought up in the Channell Editor window, BUT THERE IS NO GRAPH, and NO KEYS IN DOPE OR TABLE. The range of the graph in the view is correct, but no graph is drawn. Simple as that. The object still animates, but I can no longer edit the graphs. What the heck is going on?
The thing that I hate about learning new apps, is that, in my experience, thay are ALWAYS ALWAYS buggy. And there is no way for a new guy to know, when he is experiencing a bug, or some little button somewhere is not activated. I am not sure what I am experiencing with 5.5, but what I am not experiencing is CONSISTENCY, which is vital for me to learn any application. Something different is happening every time. And for life of me, there are discrepancies between courseware videos/PDFs and actual program.

Well I double checked my Wacom. Tip for LMB, lower finger button is MMB, upper finger button is RMB. I even duplicated these setting for Houdini in WACOM, where before they were just default settings. THey all work just fine in Rhino, MAX, Maya, Lightwave. In Houdini, RMB works in some places, not in others. In SOP it will not bring up the pop-up where EDIT GEOMETRY is, but only in Viewer window. RMB works fine elsewhere that I can see. In many RMB pop-ups, that do work with WACOM. I am uinable to select or toggle an option without changing others. The act of dragging the picker over options to get the one I need, causes those options to activate. I cannot avoid them as placing the picker outside the boundary of the pop-up closest it. I dunno, to me it feels like inadequate, and unintuitive, design. If I put away the stylus and use the mouse I can bring up all pop-ups. Otherwise, I cannot always follow the courseware videos, as I cannot duplicate the shown actions. Its very frustrating.

There are other discrepancies, that do not jive with Courseware videos.
Here are some examples
Multiple objects in OBJECTS. According to video, there is a toggle button on bottom of Viewer window that switches bettween isolating the selected object and viewing all objects in scene. Well in my case that button is dark grey and is inactive. You know how active buttons look like 3d buttons on raised lighter grey. Well over here that button is the same color as the backround grey and is inactive all the time.
Pane switcher. According to videos all panes have the button that chooses what is displayed in what pane. Well, in my case, that only works in default startup panes. If I split the pane, either Left2Right, or Top2Bottom, the new pane has that switch button inactive. The new pane is, be default, a Network Viewer, and cannot be switched to display any other view. I am going slowly, following step by step what the video is saying, and the basic behavior does not jive with instruction.
Some behavior is just plain bizzare and it feels like a bug.
Camera behavior in Viewer when its looking at null.
I have a camera looking at a null.
When the null is moved the camera tracks OK. But when camera is moved, things go to bizzare. Basically the axis of the camera, and the camera has little to do with each other. I move the camera, and I see that the transform gizmo of camera is in tottally different position then the camera itself. The camera also takes random Z-rotation, which it shouldn't as it is looking at an object. Now I realize that there are differences between Houdini and say Maya, or MAX. But in all 3d apps I know how to use, which are MAX, MAYA, Lightwave, EIU. Camera transforms are the same when looking at an object. In Houdini the behavior of tracking camera is bizzare.
I am, usually, quite quick picking up new 3d and comping apps. They all have similar tools, just in different places. Even faster when I have good training mats. But I do rely on simple fact that whatever is shown in the training materials actually jives with whats happening in the program. In my case, this does not seem to be the case.
Some definite crashes. Putting display into VEX Shaded freezes the application. This happens when using single and double buffered display.
In VEX Builder, deleting some nodes (Texture, Texture 3D so far) crashes the application.
In Channell Editor Graph. Selecting and simutaneously adjusting handle bars of multiple control points crashes the app often.
I really wish some SideFX person would explain what could possibly be happening.

I was rebuffed by SideFX guys, becouse I am learning on Apprentice. What do you think is going on. Even with my mouse the SOPs don't seem to be working. Basically, the SELECT->RMB proedure DOES NOT WORK, The RMB click does not evoke the operation. Where it sas "Select ….. then press right mouse button'. Well when I press RMB nothing happens.
Can't state it simple then that.

Something is just not working right at all. The modeling OPs are not responding.
In SOP, I have a poly box. Then added to it PolySplit OP. But it won't let me actually perform. The instruction say select, press RMB. ITS NOT HAPPENING. Nothing is working in SOP. I don't know what going on.
In Edit OP. I have it set to transform. The Edit Op is highlighted in Network. In Viewer I select points, then press RMB. At that point NOTHING happens. The X-Form gizmo is NOT showing up. This is what I was doing at SIGG on a Sun machine. But nothing is working on my Win box in SOPs. Is there an option I ahve to have enabled. The Courseware videos, do not address this. They say select points, press RMB, then move. But the moving is not happeninf, nor is polsyplit.

But thats my question, and my problem. In neither Trans for NOR Edit Op the CV's actually move. I select them with the picker, click RMB, then try to move with LMB,but they just will not move. So my question is not answered. How do I move CV's about?

I am trying to follow what I learned at SIGG and its not working as shown.
Simple thing. I want to move some points of a NURBS sphere.
Now at SIGG I was shown that you 1st select CV's of the NURBS suirface followed by RMB click to validate selection. Then create a Transform or Transform Soft op. to move the points.
Well its not working for me. Neither it is working by creating a Transform op then picking points, followed by RMB.
I am also CONVINCED that Houdini does not work correctly with Wacom Intuos. Specifically the RMB DOES NOT work in Viewer to bring up the edit geometry pop-up, though it does work everywhere else for everything else. I have a normal MS 3 btn (with wheel) mouse as backup, which is what I use in Houdini.
The basic question is? How do I simply move CV's around like in any NURBS modeler.
Houdini is some of these basic respects, is unintuitive, compared to Maya, Rhino, and 3DS MAX. This simple stuff should not be confusing.

I am starting to use Master Apprentice version 5.5. Well trying to. Basically the application is not behaving as described in the PDFs. For example, I am using WACOM Intuos. The right click button works in all windows EXCEPT it does NOT fuinction in the 3d views. The Wacom stylus is set to three buttons, and works correctly in 3DS MAX 4, and Maya 4. In the pop-up menues, it is impossible to glide the pointer at an option without turning ON/OFF other options. I am using GeForce2Ultra(64 DDR) with latest nVidia drivers on Win2KPro. In VEX whenever a node is deleted, the app freezes. The app is unstable whenever another OpenGL application, like Rhino (a NURBS modeler www.rhino3d.com ) is also running. At random times, the key shortcuts for switching views (1,2,3,4,etc..) simply stop working. Then start again, then stop, and so on. Many obvious operators do not make sence in their implementation.For example. I have a revolved surface which is using Curve1(NURBS) as a source curve. I would like to trim the revolved NURBS surface with another NURBS curve Curve2. I add a Trim node, but there is only one input. I cannot, at all, specify the surface to be trimmed, and the trim curve. Very confusing. HOW DO I TRIM A SURFACE?
The display options in the nodes do not make sence to me. For example
in the model I have two revolved NURBS surfaces. In the SOP 3d view both are visible. However as soon as I switch to Objects, one or the other disappears. Very confusing.
The PDF documentation is incomplete. For example Trim operator is missing from Glossary, and there is no example in the Tutorial and
User Guide.
