Advanced Member Vipera Posted July 2, 2015 Advanced Member Report Share Posted July 2, 2015 (edited) AUTOPO still needs some more attention. I try to make some simple shapes to make AUTOPO but it fails all the time. For example, I merged sphere and box together (not symmetrical) and try to make AUTOPO for this shape. Sphere part has open or intersecting polygons all the time. I try to make it without marking high density and without guides.

Contributor Tony Nemo Posted July 3, 2015 Contributor Report Share Posted July 3, 2015 Nice job, thanks for sharing! I was surprised at the tip, "Never use “decimate model” values over 50." as I often use it at 80 but I'll follow your advice in future.

Advanced Member L'Ancien Regime Posted July 3, 2015 Advanced Member Report Share Posted July 3, 2015 (edited) not bad at all No guide lines, no painted weights OK I'm impressed. Edited July 3, 2015 by L'Ancien Regime Quote Link to comment Share on other sites More sharing options...
Carlosan Posted July 4, 2015 Report Share Posted July 4, 2015 Ty for sharing Taros i have questions about this settings. - How can i get Crease Angle to respect the model edgeflow ? Could CA be able to analyze the curvature -vertex ratio- of the model ? - Density of quads generated automatically using local cuvature I need density variation, but cant get it work detecting the edgeflow. Do you have any hints too ? ty ! Quote Link to comment Share on other sites More sharing options...

Carlosan Posted July 4, 2015 Report Share Posted July 4, 2015 Hi ! you need to change this: Voxelize before quadrangulation = off side note: a detailed guide about every setting, how they work and how different values change the topology result -with graphical example- will be very welcome (and could help a lot to avoid trial and error) 2 Quote Link to comment Share on other sites More sharing options...
Javis Posted July 4, 2015 Report Share Posted July 4, 2015 Please remind what do you mean, there was so many fixes that possibly I missed in the list. For what it's worth, I was able to check this build, and the bug is fixed. Thanks! Quote Link to comment Share on other sites More sharing options...
Javis Posted July 4, 2015 Report Share Posted July 4, 2015 Your guys' autopo results with the new algorithm are pretty good. Chris, thanks for the write up! I think that a lot of people will find this update very useful. 1 Quote Link to comment Share on other sites More sharing options...
Contributor Michaelgdrs Posted July 4, 2015 Contributor Report Share Posted July 4, 2015 Very useful indeed. Results are better and with better topology. It needs some polish and i truly believe that its a very very good start against ...... you know what. Quote Link to comment Share on other sites More sharing options...

I will make some more tests soon but I guess the new routine should actually already follow the edges very good and produce nice polyflows without any further settings. 1 Quote Link to comment Share on other sites More sharing options...
Carlosan Posted July 4, 2015 Report Share Posted July 4, 2015 Could you please take a time to perform some test using the default bust ? im selecting the bust, merging sub-tree and performing autoretopo... but cant get a good edgeflow* detection. * Its a low poly retopo test ty ! Note using your settings i get this - 1000polys - 4ngons Quote Link to comment Share on other sites More sharing options...
Taros Posted July 4, 2015 Report Share Posted July 4, 2015 Her are my results. Seems that using Autopo with surface layers is buggy at the moment. 1 Quote Link to comment Share on other sites More sharing options...
Carlosan Posted July 4, 2015 Report Share Posted July 4, 2015 back to testing again TY TAROS !!! //edit some new test with a voxel layer model - no more spiral loops = soooo good - some edge loops here and there, need to perform more test - hand details lost > is auto-density influence multiplier working ? - with Hardsurface retopology = on cant see differences when change crease angle value 1 Quote Link to comment Share on other sites More sharing options...
Taros Posted July 4, 2015 Report Share Posted July 4, 2015 My observation is that surface mode has big potential with the new autopo routine. Look at the ears in my example. The bottom model has a better polyflow and distribution than the top one. The top model is based on voxels, the bottom one on surface mode. 1 Quote Link to comment Share on other sites More sharing options...
Carlosan Posted July 4, 2015 Report Share Posted July 4, 2015 wow, you right !! Surface > Voxel for autoretopo tool same test with a Layer Surface model -using the same settings before- note: 7stars - edge broke = no good //edit was performing better test result, see some post below this one old test pics 1 Quote Link to comment Share on other sites More sharing options...
Advanced Member arumiat Posted July 4, 2015 Advanced Member Report Share Posted July 4, 2015 I'm getting some seriously decent autopo results, not changing any settings, nor placing guides.. Great work 3DC! Quote Link to comment Share on other sites More sharing options...

Advanced Member L'Ancien Regime Posted July 4, 2015 Advanced Member Report Share Posted July 4, 2015 (edited) I'd really like to hear from Andrew and Raul about just what it is they've done to improve things so much. It's really amazing. I've being doing all sorts of goofy tests late last night and this thing is amazing. Also is it my imagination or are voxel sculpts more refined looking in the display. Somehow 3d Coat voxel sculpts look an order of magnitude better. Edited July 4, 2015 by L'Ancien Regime Quote Link to comment Share on other sites More sharing options...
Andrew Shpagin Posted July 4, 2015 Author Report Share Posted July 4, 2015 I recommend CaptureDetails = 50 and Auto density = 1 On my tests it gives best results. In some cases you need to raise CaptureDetails to bigget values, but raising leads to more stars. What was generally done - more smart curvature field calculation + better stability of solution + stars reconstruction (whenever possible). 1 Quote Link to comment Share on other sites More sharing options...
Taros Posted July 4, 2015 Report Share Posted July 4, 2015 Andrew I would like to save settings for different situations. This would be great. 4 Quote Link to comment Share on other sites More sharing options...
Taros Posted July 4, 2015 Report Share Posted July 4, 2015 For your tests: To be really shure about good settings use always low poly resolutions. The better the results there, the better they are for other high res models. Quote Link to comment Share on other sites More sharing options...

Javis Posted July 4, 2015 Report Share Posted July 4, 2015 I absolutely agree. Having presets for at least some basic types of situations, and the ability to share them, users will not have to do so much guess work. Andrew I would like to save settings for different situations.

Taros Posted July 4, 2015 Report Share Posted July 4, 2015 In the meantime I've made more tests and I think I have very good settings for the current version. Try this, it works well for low poly models too:Capture details: 50% (The higher your Poly count, the higher details can be. But try it careful and start always at 50%) Auto density influence modifier: 1 Voxelize Before Quadrangulation: on Voxelized object poly count: Start at 50% of your high resolution model in rounded thousands. My max value was 3.000 when the mesh began to get worse. My mesh has 5.8 million polys and a value of 2.000 was the best one. Decimate if above: on Decimate model value: 100 Smooth resulting mesh: off No density set needed. No guides needed.I got really impressive results with this settings. 1 Quote Link to comment Share on other sites More sharing options...
