Member Alco3d Posted April 10, 2015 Member Report Share Posted April 10, 2015 Hello everyone! I have difficult model with many holes and mistakes of topologi. Manual retopologi of that take many time. AUTOPO not working fine and is crashing every time, although i've good configuration PC. No matter i doing it on hipoly or lowpoly i have problem with it. Even i have problem when try AUTOPO on basic head. Seems good solution for me could be quadringulating of mesh from triangles to quads. I don't care about weight of model, no difference to me how much polygons will i have, because this model won't be animated, just be rendering. And i don't want to bake model, i want to leave everything as in voxel room. In earlier versions 3DC AUTOPO was called Quadringulate, right? But seems to me, it was much easy, because 3ds max and Myay do that simply and quickly. Why i can't do that in 3DC and i have problems with AUTOPO, why i can't to leave density of mesh and just transform triangle to quads? I so tired every time restart 3DC. Glad if you'll help me. About my a configures: i have i5core with 4 cores. But 3DC take only 25% CP, i.e. 1 core. Is 3DC not support multithreading? Quote Link to comment Share on other sites More sharing options...
Contributor Malo Posted April 10, 2015 Contributor Report Share Posted April 10, 2015 3d coat have problems with holes and unclean meshes in autopo. There are some fixes in the beta builds, maybe that helps you with your problem. But i would import the object in VoxelRoom as VoxelObject. This close every hole and missmatches. Then you could start autopo with this mesh. Quote Link to comment Share on other sites More sharing options...
Contributor Michaelgdrs Posted April 10, 2015 Contributor Report Share Posted April 10, 2015 or export high poly and quad it with max or maya , Quote Link to comment Share on other sites More sharing options...
Member Alco3d Posted April 10, 2015 Author Member Report Share Posted April 10, 2015 (edited) Now i imorted as voxel object and started AUTOPO, but it freeze my computer out. Yeah,michael, i can use /max or Maya, but how can i do that in 3DC. Zbrush from the very beginning to sculpt poligons and let user to unwrap extreme high poly. 3DC has only one option - AUTOPO and nothing else. May be i can be wrong...

Contributor Michaelgdrs Posted April 10, 2015 Contributor Report Share Posted April 10, 2015 so far i had no issues with autopo , only acouple weird results , solved those by adding manual lines , or by doing retopo with different settings , a clean voxel model plays a huge role in autopo Quote Link to comment Share on other sites More sharing options...
Advanced Member arumiat Posted April 10, 2015 Advanced Member Report Share Posted April 10, 2015 What are you ultimately trying to do? Reduce the number of polys on your model? Post a screenshot of your model. Quote Link to comment Share on other sites More sharing options...
Member Alco3d Posted April 10, 2015 Author Member Report Share Posted April 10, 2015 Hi, Arumiat! I try to make from my highpoly surface including triangles, hightpoly of square polygons, for further unwrapping and texturing, without AUTOPO and baking. Pure highpoly and diffuse map, without Normal maps, displacement and other. I don't want to rebuild, reduce or increase count of polygon, how it's going by AUTOPO. I want to merge two triangles for one square)) (BTW - why in surface mode 3DC make mesh but not polys? Why dont' let to choose?) Why i can't use AUTOPO i wrote above - my model has many mistakes and it's going slow, and after retopo i lose sharp edge in hard surface. I 'll repeat, may be i doing wrong, i newbie and know a little.) Quote Link to comment Share on other sites More sharing options...

Advanced Member arumiat Posted April 11, 2015 Advanced Member Report Share Posted April 11, 2015 (edited) Not sure of a method in 3DC. The remesh modifier in Blender would produce a 'clean' copy of your object made from quads, and has the benefit of cleaning up holes in your mesh very well. You can loosely approximate the number of quads with octree depth. Don't know if that helps you though Edited April 11, 2015 by arumiat Quote Link to comment Share on other sites More sharing options...
Member Alco3d Posted April 12, 2015 Author Member Report Share Posted April 12, 2015 Ooo! Thanks Arumiat! I'll try it right now! Quote Link to comment Share on other sites More sharing options...
Reputable Contributor AbnRanger Posted April 13, 2015 Reputable Contributor Report Share Posted April 13, 2015 I think Andrew certainly needs to revisit Auto-Retopo again, but it seems Raul is already working on a new quadrangulation tool, so maybe this is the alternative approach Andrew eluded to before? In the mean time, I always try to create a less detailed duplicate of the model > run SMOOTH ALL before running Auto-Retopo, and it helps much of the time. There are instances, though, where it takes way too many re-attempts to get a suitable result, and that's why I only use it about 1/3 of the time. The Strokes tool is an Auto-Retopo tool in it's own right. Sketch out the topology or create loops > one cross-section and it generates the mesh for you. I'm trying to see if Andrew will add the ability to use the selection modes (Line, Rectangle, Ellipse, Freeform, etc) in the E-Panel to quickly create accurate strokes, and that could shave the creation process down much further...and make it a better alternative in most cases.

Member Elowan Posted April 13, 2015 Member Report Share Posted April 13, 2015 cross-section(s)? I thought, this will not work, when AUTOPO? Really hope, this feature getting some overhaul/poilsihing to be on par or better, than Zremesher2.0 Cheers Quote Link to comment Share on other sites More sharing options...

Member Elowan Posted April 14, 2015 Member Report Share Posted April 14, 2015 (edited) hmmm - did not get, what you mean.... I think "doing re-topo by hand, but with 'constrained' shapes"? The thing I experience is, that edges are not preserved as straight verticle or horizontal lines - instead they are kind of "winding" or turning - even when hand-painted some straight lines in... So the loops are going kind of diagonal thru/over the object - kind of hard to explain for me (got no image to show you atm) Cheers Edited April 14, 2015 by Elowan Quote Link to comment Share on other sites More sharing options...
Contributor Tony Nemo Posted April 14, 2015 Contributor Report Share Posted April 14, 2015 In the Retopo room, use the Strokes tool to slice through the object by starting outside the object (the line can be constrained to horizontal, vertical with Shift key), You can set the number of polygons in the bar above.

Member Elowan Posted April 15, 2015 Member Report Share Posted April 15, 2015 ahhh, ok. So no AUTOPO, but manual re-topo @Tony Nemo Yes, I did it the way, you described - but got the results, like I mentioned... maybe it was an older version, I will try the latest one and see, if it will work. Cheers Quote Link to comment Share on other sites More sharing options...
Member Elowan Posted April 21, 2015 Member Report Share Posted April 21, 2015 Will the AUTOPO function be looked at / improoved again? If so - please try to add a "Preserve Edges" function, so the the silouette stays 100% intact and the algorhythm goes from there... Cheers!

Cheers Auto-Retopo is NOT the ideal tool for every situation. In fact, that's precisely what I've been trying to convey here. The Strokes tool is something of an Auto-Retop tool all by itself. With Auto-Retopo, you often need to create guides to give the tool hints to how you want the topology to flow. With many primitive shaped objects, like human limbs, fingers, Torso, etc. you can create a few guides + one cross-section and BAM....3D Coat creates an entire mesh encompassing that area. There are many objects, though, where Auto-Retopo works splendidly. I find that to be objects that rather primitive in shape. It tends to struggle a bit, here and there, when working with rather complex objects. Just telling you what I've learned...take it or leave it. 1 Quote Link to comment Share on other sites More sharing options...

Andrew recently revisited the Autopo tool and most definitely will be in the future. 3DC is always being constantly improved. Quote Link to comment Share on other sites More sharing options...
Advanced Member blade33ru Posted May 1, 2015 Advanced Member Report Share Posted May 1, 2015 FYI ive found in autotopo if you raise the value where it says decimate model till getting desirable polycount to about 80.000 i get a much better solution on complex models Quote Link to comment Share on other sites More sharing options...
Advanced Member blade33ru Posted May 1, 2015 Advanced Member Report Share Posted May 1, 2015 im glad to hear hes revisited it. at the moment im decimating and exporting scenes to zbrush because they really improved the autotopo there in the last revision or 2. its very very precise and super fast without guides. plus it can handle super high polycounts. sometimes 3d coat crashes with high polycounts outside of the voxel room. high polys in retopo or UVs often crash for me Quote Link to comment Share on other sites More sharing options...
Member Alco3d Posted August 8, 2015 Author Member Report Share Posted August 8, 2015 In the last release (4.5.09) i can't remove old AUTOPO curves. There spoil me my further retopology. How can i delete they? Thanks! Quote Link to comment Share on other sites More sharing options...

Member reidh Posted July 23, 2016 Member Report Share Posted July 23, 2016 (edited) I understand, or think, that 3d Coat has an automatic retopology feature. If this is so, I would like to know. I want to know also, if it is easier and/or more automatic than that of Blender retopology with J. Williamson's retopology add-on.

Carlosan Posted July 24, 2016 Report Share Posted July 24, 2016 Hi ! You mean if 3DC has equivalent tools to Contours and Polystrip ? I have not bought the addon but let me show you the equivalent tools in 3DC. 3D Coat is much more complete than RetopoFlow (previously known contours + polystrips). If you're looking for a complete retopology solution then 3D Coat is probably the way to go. Quote Link to comment Share on other sites More sharing options...
