View Full Version : Low Res Stray Points and Save Problem

06-04-2008, 01:28 AM
I've looked everywhere but I can't seem to find anyone who's had this problem. Stray points usually seem to happen at high resolutions, but for me it only occurs when I get down to sdiv level 2. From there things get even worse.

Here's my tool at level 7:
Everything's working perfectly.

Level 6, 5, 4, and 3 are all also ok. Then I get to level 2:

I realized that these stray points seem to be coming from the corners of the mouth:

And the bottom of the chin:

If i go down to level 1 things get really crazy:

After that, going back up to level 2 is hopeless:

I save my tool every once in a while and the first few saves don't have this problem at all. It seems to have come when I hid some of the model to focus on a specific area. After that all my saved tools have this problem.

Also, I've realized that I can't save my tool anymore unless something is hidden. If i unhide everything and try to save, it crashes. I even tried saving with the subtool master but it also didn't work.

Has anyone experienced anything similar or does anyone have any idea what could be wrong? Any help would be greatly appreciated as I'm stuck at this point, unable to keep working on this project.

I had a similar issue a couple of times (though not as dramatic). Unfortunately I don't remember what level I saw the stray points in but it may have been lvl 2 or 3. I smoothed the stray points at that level then did smart resym to make sure everything was in place and everything seemed fine afterwards.

Once I saw the stray points I didn't go down a level, but I could see how going down and then back up could cause more problems.

I'm curious to if anyone else has insight into this issue as I've seen it more than once but it's completely intermittent for me.

Don't know about the inability to save after hiding parts though... I haven't run into that.

Thanks for the help Tony. Unfortunately, smoothing it doesn't seem to be working. Could you be more specific? Did you smooth out the area where the points came from or the actual stray points?

Smoothing out the area isn't doing anything for me and I can't even smooth out the points because they sort of go into infinity :curious:

I kind of figured it out. Well not really but I was able to fix the problem a different way. I decided that since I'm only using this model for a still I don't need the lowest subdiv levels, so i just got rid of them. Everything seems to be working fine now and I'm finally able to finish this project. Easy fix. :beer:

I'm glad you were able to workaround it.

FWIW, when I had the issue the stray points weren't out to infinity so if I recall correctly I was able to smooth the actual points. Sorry, I guess my issue wasn't the same as your just really similar.

I know such problems when you import again the base mesh over a previous when with a vertex order which is different, but not in that way!
Just to know, what was your workflow to create your head? importing a base mesh and just sculpt?

you could try export to maya and see if theres any strangeness to be found even on the higher subD levels. If not, try "recontruct subdiv" to see if you can properly rebuild the lower ones, when they are deleted.
Not likely, but possibly you could even export highest subD level to maya for a cleanup before the reconstruct.

Theres also a complete workaround, which is to export the lowest (or 2nd lowest) level to maya, fix it. And use retopo to project the highres onto the new clean lowpoly.
