Hello,
I have been using the Aprentice vresion for about 3.5 months now and am experiencing segmentation faults with increasing frequency. I'm hoping that somebody can give me some strategic ideas for trouble-shooting these issues as they now happen every 5-10 minutes preventing me from making any meaningful progress with my project. Some details:
I'm working on a basic character animation short and my workflow progressed as follows. Modeling went smoothly with no errors that I can remember. Texturing started to reveal some instability. I really began to experience some “Segmentation Faults” with uv editing. I noticed that making rapid selections, adding/removing points, seemed to frequently cause errors. Using lasso selection and secure selection off also seemed to increse errors. I would estimate that during this phase I was experiencing them with about 6 - 10 times a day during an 8 hour work day. Rigging went very smoothly - I don't remember experiencing many errors at all. Binding and Weighting saw an increase in errors; again they popped up when making selections, adding/removing points, lasso/secure selection off. I was able to modify my wotk habits to get around the errors but not without feleling like I was being incredibly inefficient - many Q's and right-clicks. Animation has been a complete nightmare. Positioning/Selecting joints/ctrls, scoping/editing channels, playback, scrubbing, using the channel editor, and anyting else I'v tried with animation in one way or another has resulted in a Segmentation Fault. As I stated above, the frequqncy of these errors has prevented me for making any measurable progress with my work. I don't know if I'm working improperly within Houdini hence my files are screwed up or my workstation configuration is the culprit. I uninstalled/reinstalled, upgraded
Houdini versions and Video drivers several times to no avail.
Workstation details:
Dell precision 530, dual 2g Xeon Processors, Win2k service pack 3, Nividia
Quadro 900xgl video card with 42.82 drivers just upgraded from 41.09, Dual monitors, 1 gig Ram. If there is anything I left out please let me know. If anybody has any ideas of how I can trouble-shoot these issues pleeeeeeaaaaaase forward your suggestions. I'm desperately trying to finish my demo reel and I don't want to have to start over with maya. Thanks for your time…

Yes, I do mean the chanel editor (sorry); but nothing seems to get it back other than a complete restart. Even closing and reopening just the file does nothing, nor does exiting and ropening the program. I have to restart to bring it back…I should also add that about half the time with this problem houdini goes into a segmentation? error so my only recourse is to restart, but the other times everything else seems to be working fine, but the channel editor won't come back.

Hello All,
I've recently started animating and discovered that frequently the CHOP's graph/table/dopesheet window turns completely gray. It has happened with both several channels scoped and just one channel. I can still see the groups, bars, buttond, etc. but I can't rescope any channels. Nothing else in houdini seemes to be effected but everything I've tried can't bring my CHOPs back to life. Additionally, this problem is independant of whether I'm using CHOPs as a panel or torn-off window. The only thing that remedies the issue, only temporarily, is a complete restart; closing the file/houdini and reopening either does nothing.

Any Ideas; Thanks..

I need to remove and then add kinematics to include more bones on my skelton but I've already done all of the weighting. When I attempt to do this, I loose all of the weighting info. on the model. Can I do this without loosing my bind weights?

Hey there,
I'd like to modify the position of some bones, but I've already captured and weighted my model. I've tried bypassing the capture SOP and then repositioning the bones, but when I reactivate it, I'm getting unpredictable weighing all over the model on points that were not influenced by the bones I moved. Is there a way to export the weighting and then import it after I repostion the bones?
Thanks…

Okay,
I've tried capturing my model to my rig as described in the Hoodhik tutorial. I select my model as the geo object and then select the model again as the root of the bone heirarchy. When I RC to complete Houdini seems to cook instantly; much quicker than in the Hoodnik tutorial. I'm not getting any geometry coloring corresponding to bones and when I edit the Capture Regions and make transformations, it appears as though no binding has occured. My model is a SubD, but I dodn't think that should matter, should it? I'm also getting a yellow flag on the capture sop that tells me “Warning: No capture regions were found from the given parent.”
Any suggestions on how to troubleshoot this will, as always, be greatly appreciated. Thank You.

Thank You Steven,
Your suggestions were an immense help; there is now way I would have figured out some of that stuff on my own. You're doing a great job…

Hi there,
I've been working with the Lava VOP tutorial for a while and was hoping that somebody could elaborate on the part where Peter discusses the “displace bound” parameter. I can get it to work with the example in the tutorial just fine, but I'm having the “displacement cracking” issue with my own model and shader. I'm using a much subtler displacement than the tutroial but the displace bound parameter is having no influence on the cracking. Any ideas? (nvidia 900xgl quadro card)

I just finished the “vops_textures” tutorial and was able to use my highres image without a problem so everything seems to be working. Still not sure why I couldn't get them to work with the layered shader…

I'm using the files in a layered shader (the basic technique taught in the texturing tutorials); I tried both .tif and .tga files. For example, in photoshop, I created a 2000X2000 image file at 300 dpi which I attached to the shader. When I applied the shader to my my model, the primitive groups that I applied it too went totally invisible or transparent in the viewport and they wouldn't render. Additionally, I couldn't get the texture to appear as background images in the uv layout pane at these sizes. I reduced the size of the textures until they would work in the viewport and render which turned out to be 480X480 at 72dpi, but at this size the quality is terrible; the stripes are very jagged/pixleated in both viewport and render.
I must confess that I didn't reduce the size by single increments until they worked; I made reasonable reductions until I tried 480X480 which I did because that was the highest size that I could get the “save texture image” function to work. Am I doing something wrong? ( I using a quadro900xgl on win2k) Thanks again…

I'm working with the aprentice edition and having some texturing issues. I have a zebra that I want to apply some texture maps to that I painted in photoshop. I wasn't able to import any images over 480X480 at 72dpi (perhaps this is some limitation of the Aprentice Edition?). I'm attemping to get crisp “wavy” stripes, but at 72dip, the stripes look very “pixelated”.
I'm relatively new to this, obviously, and not sure the mose effective way to remedy this. Any suggestions will be greatly appreciated. Thaks on advance.

Does anybody know why the viewer is showing the black stripes on my zebra texture as aplha? Fast mantra renders them black, but they show up transparent in the viewer…graphics card is Nvidia Quadro 900xgl.

I would like to export a 2d UV map of my subD character to a file so that I can import the file into photoshop for texture painting. I don't know how to do this in houdini, maybe with UV unwrap, and I can't really find specific information on this in the help files or the web. If anybody knows how to accomplish this, please advise.
Thank you very much…

Hi there,
I've been at this tutorial a few times and I keep having the same problem at the same point. In the tutorial (part 2), when I create the wire frame material and plug it into the color input of the output node, my renders go black. Everything works great up to this point but from here on out I can't get anything out of my renders. I've experimented with several different materials and they all give me the same result: black renders in both mantra and the view port. I'm also getting an error message in the Houdini Console the says “WARNING: Invalid state name lava”. I've done this tutorial several times and made sure that I named everyting exactly the same way Peter did, case sensitivity and all. Does anybody have any idea what I'm doing wrong?
Thanks in adavnced.

I'm attemptig to duplicate half of a model along the x axis and I would like to make sure that all of the points that lie on the center line of the model fall at zero in x. I'm attempting to translate them with and edit OP and snap them to either the z axis in the top view or the y axis in the front view and I can't get them there. I've tried all of the snapping options, but no matter what I do, the snapping gravity won't set it right on the axis. Any Ideas?
Thanks
Thanks
