Parameterizing texture atlas... hangs at 70%

I found this thread, but no resolution seemed to be present there.

I have a full body solved and meshed. I have three versions right now that I'm testing, a 7.5 million poly, 2 million poly, and a 500 thousand poly version. No matter what I try I either get an out of memory error or it just hangs for hours. This has happened with a 8000x1, 4000x1, and now currently on a 2000x1. I was able to get a 2000x8 to export on the 7.5 mesh at one point, but the result was horrible. There were random black patches everywhere and the seams showed. I've been able to output up to 16k textures in the earlier PS versions, even the 0.9 beta. My machine is not a beast, but it has handled much larger pieces than this previously, including a scan of the the front of our office building.

Specs:
OS X 10.8.2
24 GB 1066 MHz DDR3 RAM
2x2.93 GHz Quad-Core Intel Xeon
2 ATI Radeon HD 5770 1024 MB graphics cards

PS version:
Standard
1.0.2 build 1824 (64 bit)

Hello David,

Please try latest version of PhotoScan - 1.0.4 build 1847.

Also please specify the version release number used to generate the model. Just for case I recommend to rebuild the model based on the same dense cloud (if present) in 1.0.4 prior to texturing.

Apologies, I didn't see that a new release was available. My update notifier was unchecked foolishly.  I will try this and re-mesh before trying texture as per your note. The geometry was created on a PC version then came to me on OS X. Same build number I believe, but not sure off hand. Thanks.

Bingo! That seems to have fixed my issue completely. Just did a 4096x1 texture on the 500k poly model and it worked. Doing an 8000x1 right now and it has two minutes left. Much better. Thanks for the help.

Here's a quick screen cap of the final 16k texture of the face. It all seems to be working wonderfully now.
