Cannot wait for 64bit and being able to sculpt over 10 million polygons reliably, as well as be able to support larger than 8k textures
The problem is that their is a difference between sculpting (brush strokes) and several operations, like Projections. Projection can need 4 times more memory than usual operations, then yes, if ZBrush is at its limit with the mesh itself, things can become problematic
ZBrush crashes when exporting more than 7 million polygons as .OBJ. Paul Gaboury mentioned this could be a legacy issue because ZB was never built to handle these types of sizes.. It's possible to use Goz to Modo but not ideal.
A trick is to try exporting through 3D Print Exporter or through Decimation Master (you have export options in these plugins), which are using a specific exporter, not the ZBrush native one).
I would be happy to share any data with Pixologic. I also have a bunch of ideas that could be useful for ZBrush 5 to help the industry that deal with scanned data. Zbrush hasn't had much love with regards to supporting the growing scanning industry and we could do with some
Things like intelligent hole fill, multi camera import, paint layers. FYI im on the ZBrush beta but have never heard anything since I signed the papers back in 2011!!
Well, all your ideas are more than welcome. We are now two team members at Pixologic using PhotoScan and working with scan datas and facing real issues ourselves is also the best thing to understand your problems.. and as you can imagine, it's not the same as having a "bug report"
@bmc130 : yes you can paint on texture directly with the help of ZappLink and Photoshop by projection, but not a "real" paint on texture like you are doing on some other software.
Sadly there are many bugs with this method, going back and forth to PS, projection errors, seams, back side projection etc Also the lack of paint layers is a huge missing link.
Yes, I can understand, in a way, I was just answer on the question on a technical point of view.
But without ZBrush it would be near impossible to work with RAW photogrammetry data from Agisoft Photoscan. It's an essential part of the pipeline and incredible at that.
And that's why all feedback is more than welcome.
At which email can I contact you / chat with you?
Also, I'm doing an online webinar in France tomorrow about ZBrush and scan datas. If you have extra samples or raw images, I'll be glad to show them, including what can be wrong in shooting, even with your fantastic setup!
