I like the new “Layout All” system very much, hotkey L. Inside the SOP it behaves logically, 99% times I can rely on automatic layout.
Now I am trying to make system in organizing my /obj level. I am almost satisfied, but it behaves inconsistent:
- when working with the file: children with “newer wire” jump to the right
- after save quit reopen: other sort logic is used, probably node “Created” date and time?
Does anybody know, how this system works, please? Probably SESI could unify it? Or could I write small python script and hack/set “Created” time alphabeticaly?

Please, did you manage to import channels with names from TD to H?
I have tried to investigate and there are small differencies in .clip as Houdini and Touchdesigner creates them. Please, can anybody help?
Houdini:
{
rate = 24
start = 0
tracklength = 240
tracks = 1
{
name = chan1
data = 0 0.25881904363632202 0.5 0.70710676908493042 0.86602538824081421
Touchdesigner:
{
rate = 60
start = 0
tracklength = 600
tracks = 1
{
name = accxyz1
data_rle = -0.00669861 @2 -0.00994873 0.000991821 @2

Hello, the docs say about quickmarks:
“They are not saved with the scene file”
http://www.sidefx.com/docs/houdini/network/navigate#quick [www.sidefx.com]
Please, is it possible to set the quickmarks with python and have the quickmarks set on houdini startup?
Somehow to “hack to default addresses” for these keys:locations? Without having to manually set them each session?
1: /obj/geo1
2: /obj/dopnet1
3: /obj/ropnet1
4: /obj/matnet1
Please, any tip to better use of quickmarks is welcome.
Could SESI make them persistent? Or why not?

@Guillaume, please, I have tried this new function chinputlimits().
- chinputlimits(0,0,…) iterates fine and gives me min/max
- chinputlimits(0,1,…) seems to evaluate just the first sample … not over all the range
Am I doing something wrong? I have attached my file.

Technical Discussion » OpenCL multiple GPUs in one PC / automated distribution of slices

Please, I have 4 gpus in one computer now. Is there any management system, which could help me distribute the HOUDINI _OCL_DEVICENUMBER and run more instances of Houdini simultaneously, each calculating distributed slice on one computer? I have asked ThinkBox Support (their Deadline can distribute renders 1gpu:1frame) and I got answer, now the situation is this: “ I am not aware of any plans to add that support, but I will pass your interest in this along to the dev team for future consideration. ”
Well, I am just a small freelancer trying to get maximum of my hw and sw, I have Indie license. I am not doing big VFX, ram on those cards is ok for my sims. Maybe my needs are not from big business, so the tools are not typical for my needs, which is understandable.
Should I wait for SideFX to automate or use multiple GPUs?
Or create my own automated batches, HDAs? Can it be automated and managed quite easily?
Or search for other management software?
What do you think? Do you have any indices?
Thank you for any insider info or heads up.

As regards locking of the horizon … isn't it possible to script it somehow? The Z component of rotation should be zero, but simple “lock parameter” doesn't work. It is deeper somewhere, does it really require Sesi to implement it?

Btw important notice: I have tried 3D mouse formerly on one conference and I was disappointed. Now I know, that it was because of reversed orbit settings. Everybody has his own “understanding” if the mouse should be reversed or not. Now I have borrowed one from my friend and he told me to try reversed and … wow

Hello Chriss,
I am:
- on Wacom Intuos many years (XL for 30" LCD), happy
- without mouse many years, quite happy (you know, no wheel)
- with Space Navigator second day, amazed
So I dont have much experience with 3D mouse, but I think that wacom is no problem. Or why should it be?

Hello Albrecht,
thank you very VERY very much for your answer. You are right, that “side-stepping” solves this strange “gimbal lock” I had.
- my problem was that I had “zoomed in” and I thought that I am “stepping forward”, right?
- I thought, that I am “stepping forward” and I was just moving the pivot closer to the camera and “locking” the pivot to the cam
Well … there is not “step forward” with the 3D mouse, right? This probably makes sense
Now I am happy and I recommend 3D mouse to everybody. It is amazing. I have just the Space Navigator, close to the keyboard, and I am quite able to orbit with midfinger and forefinger and also can hold ctrl/shift with my thumb. This should be great for modellers.
Many thanks Albrecht!

Please, tell me if I understand it right.
With 3D mouse:
- the position of the “camera/view pivot” is somehow approximated and moves relative to the camera/eye
It is really hard to use. I have Space Navigator. Please, if you have a 3D mouse, try this:
- make two cubes, one at origin, second far from origin (10,0,0 is enough)
- orbit around the “origin” cube … this is fine
- move to the “far” cube and try to orbit around it … this goes quite well, the pivot “quite goes with you”
- move back to the “origin” cube … now the pivot is really somewhere, unknown, I dont know where
- try to move to the “far” cube again … now the pivot is unusable for any of the cubes
- after some more attempts … this seems to approximate “pivot position = camera position”
I may be wrong, as I have the 3D mouse second day, please correct me.
Setting the pivot manualy (Z or Shift-Z hotkey) is not a solution for this behaviour.
With classic mouse or Wacom tablet:
- view and camera rotate around a DEFAULT RELATIVE pivot, which is in front of camera and moves with the camera, and is relatively fixed to camera/eye (Euler tumbling)
- I can set the pivot to some geometry (Z or Shift-Z hotkey)
- this behaviour is not perfect for classic mouse, but it would be good for 3D mouse, or why not?
- do we have hotkey to reset the pivot to that “DEFAULT RELATIVE”?

Hello, just a small notice, as regards the attached file and your question “Why doesn't it return anything for the other attribute, ‘myrand’?”
It is because you reference this SOP “opobj/pc_open_stuff/attribcreate__ptnum” but you specify the “myrand” attribute later in another SOP downstream.

Same thing happened to me yesterday. Your solution helped me, I hope. Thank you!
I have noticed, that in the big file, there were many Mantra IPRs, almost thousand. Maybe that is the bug somewhere. If SESI is interested, I may send the wrong hiplc file.

Hello, please, did you find a solution to set the default position of an orthographic camera well beyond the bounds of the viewport (or the homing object)?
Why not to set the scene origin (or the homing object) right in the middle, between the clipping planes?

Hello, unfortunately I did not find a workaround. Maybe you could write a file cache outside the loop, and then read the specified frame inside the loop? EDIT: I mean, use the File Cache SOP and Save to disk outside of the loop, do you understand? I did not test this.
