[Solved] Strokes tool (Retopo) not generate mesh for cyclic mesh


Recommended Posts

I have not seen this problem before (or could adjust some property then do again, it have wroked,,)

But about sculpt mesh (made by rotate surface), I can not manually retopo with Stroke and path.

it only generate 2 side(first and end)  poligons around sculpt mesh.

I change stroke ,path more short (just start from bottome to middle height of mesh) but it show same. (only 2 line poligons are generated)

Can someone test this scene  please?

At first I tried to keep Suface mode (sculpt mesh), and change as Voxel mode (with dense), after all not work.

 change Spline points density high and low, neither not work . So I think I miss use some option,,

my 3d coat version is 4.8.38.SL (windows 64bit Open GL)

Something this happen if the model is very tiny. Try scaling it a bit.

Thanks advice, but when I use measure tool, it is almost 240 mm (24cm etc), and recently i just use default settings about scale things.

Then do not know how 3d coat count mesh too tiny etc..

then as you suggested, I scale up 2.5 and increease resolution with surface mode. and try more simple short path, but not generate well.

I know sometimes, if the path end or start are located bottom faces, (hard angle), the area cause issue, but usually middle stroke area generate well,

but about this mesh (use new curve tool) I can not generate faces well,,It try with surface mode, dense mesh, (wire frame to check)

Only bottom area , generate poligons.

Thanks to take your time Carlosan. Then as you know, I made this mesh,  to test new Swept Curve option (Rotate Surface),  htne it seems not work for me.

but when I made  almost same shape (voxel),  by Primitive tool (adjust curve graph) , then  Strokes tool not cause issue.

I think if mesh made by swept tool (surface mode) can keep  edge shape good, but cause kind of  problem when re-topo with strokes tool ,,

Though there may be workflow, voxelize and clean it. (I could not do it well)

I have had many stroke failures over time. Some leave random faces inside the model that  must be ghosted to find and delete.

Yes I understand what Tony mentioned. but I could not clean it well about the mesh (surface)  generated by the swept rotate surface tool.

I tried it change as voxel . then scale,, and fill or close hall ,smooth etc  , but there seems issue here or there in volume. (voxel arrange is somehow different from usuall clean voxel mesh),, then after all,, test with Surface mode. 

As for me, I can not find issue about the mesh. but apreciate if you test the file. (up-loaded link)

Test done: same error.

Yes thanks! 

then I think, my mesh seems too thin when I generate with swept rotation. as Tony adviced,,, (so it cause double side mesh )

if I set plenty thickness when generate , and remove curve,, and voxelize,   seems work..  ( keep thin voxel mesh for bake only,  copy another mesh which add more thickness and voxelize,, may work I feel,, I may try again,, this workflow.

Hi.
Thanks for the feedback.
In the development of a new version of the tool Stroke.
