[Solved] Autopo not working at all ?

[Elowan]

hi there and a merry christmas everybody!

 

today, I tried to AUTOPO a model - but I get no results:

 

- Imported highpoly via menu for AUTOPO

- Set polycount

- skipped poly-desenty

- skipped help-lines (also tried with adding freehand-helping-lines)

 

After calculation was done, I went to menu Export Retopo-model - but it is just empty.

I did not see any re-topoed model in the UV-tab (just the highpoly)

3DC generates a retopo-group an another "surf" object in tree - but shows nothing...

 

I am on 4.1.17 D 64-bit windows Cuda DX

Nope. Autop works as it should.

 

- Start with basic head, symmetry on

- run autopo with 4000 faces

- skip both windows

 

Now in Retopo Room klick on File-> Export Retopo Object and you got it.

 

You dont see anything in UV-Room or Paint Room because you have to bake it first.

It is a little bit confusing for new members. Because you have to setup UVs in Retopo Room first and not in UV Room.

After baking, you could redo your UVs in UV Room if it is neccessary.

Hmmmmm, my exported fbx is just 5kb in size and contains no poly verts or whatever...

I did Import a 1mio + poly. Fbx direct into retopo room and run the autopo tool.

Then exported it from file export retopo object.

Did I have to UV it first, before exporting?

Maybe I should try 4.5 version

No you dont need UVs.

But first i would test with the basic head like i explained. It should work with 4.1.17, too.

If this head work, then the problem is on your import options or model itself.

[Elowan]

Ok, the demo-head works 100%.

 

One difference I notice, my object is not origin/pivot at 0,0,0. It has got an offset from the

center of the axis - is there a way to "center" an imported object in 3D Coat?

 

Cheers

[Elowan]

ok, I think I´ve found it... but still no (re) topology object visible/empty export

 

hmmm, maybe there is an issue with the axis?! "transformed" my object, so that

is sitting at 0,0,0 - but when turning on symetry-planes, there is a gap to the x,y,z axis (see image, please)

I see.

Your Pivot is sitting on XYZ 0, but that dont represent you whole object.

 

Anyway.

Retopo is designed to work in the posirive side of an axis. X+Y+Z+

If the object is compledly on the negative side, lets say X-, and you have symmetry on, there is nothing to calculate on X+

Thats the reason why you dont get any retopo.

Turn of symmetry and it should calculate your auto retopo.

 

But still, there is no problem with autopo itself.

 

If you have still problems, send me the file please, so i could take a look over it.

Ok, I turned off symetry (as there really is no on the model) - but 3DC does not generate a re-topoed mesh, anyways...

After a look into the file, is see that you have many holes in your Surface.

Looks like Auopo have some problems with that many holes.

 

There are two quick workflows for your problem.

 

1. Duplicate your Surface Object, convert it to Voxel and use that Voxel Object for autopo.

You could delete it after you are done with autopo.

 

2. use Voxelize before Quadrangulation.

 

 

Version 1 have more controll over the object. You see what you get for autopo.

Version 2 ist an automatic option, less controll at all.

 

I hope that helps you.
