Unhappy ghost trouble again

I have met this beast before ,converting to sub D and then undoing it just to track the look of the model but on the last return to polygons it has kept the sub D somehow locked to the polygon form. when i deleted the history to try to get rid of it it has gone to wire "weird" i managed to pull it apart so you can see it what is going on ... dose anyone know what i have done

i have this prob many a times
i get it afeter using 'ctrl+z' to undo a mesh conversion

i dont know of a solution an i would like to know also

the only one i have so far is reverting back to a previous saved version

if u go into vert mode can u move the extra meshes verts and does it have any effect on the model other that move edges that dont have faces

Talking just a note for pbman

in case you undoing wire mesh for the same reason as i was ... softening the normals all the way gives a more better idea with out the risk,as it is truer to the geometry and it changes nothing on the model... thats if that is why you are converting

I've just made two buttons up on my shelf.

One for converting the selected poly object to subds.
The other for converting a subd model to polys.

Rather than do through the same trauma with the do and undo method, I just convert then convert back.

The script behind the two buttons I use is:

Polys -> Subds
doSubdivCreate( "2", { "1","1","2000","32"} )

SubDs -> polys
TesselateSubdivSurface

I just ctrl-shift then selected the option from the menu. This way you get the icon and status-bar text set for each button. It also means that convert buttons will keep the current options for each tool.

Just make sure you set the Tesselation Method to vertices, and Original Object to replace for the subd -> poly conversion.

The poly->subd conversion should have the Keep Original checkbox unchecked.

Failing that, if you know your way around the hypergraph, you can show all nodes of an object then just delete the part of the model that didn't get uncreated when you hit undo.


Should keep you out of troube guys.
