Major Sub-D glitch!
Hi,
I was well into modeling a character for a short movie and I ran into into this weird bug: whenever I convert an a poly object into subsurface division (alt+`) it works fine: Before conversion: http://www.student.cs.uwaterloo.ca/~.../3d/help/1.jpg After conversion: http://www.student.cs.uwaterloo.ca/~.../3d/help/2.jpg so far so good. The trouble begins whenever I undo that conversion (using 'z' key), the resulting shape is some sort of mix between poly and sub-d surface: http://www.student.cs.uwaterloo.ca/~.../problems1.jpg a closer look: http://www.student.cs.uwaterloo.ca/~...lems_zoom1.jpg There seems to be some sort of residual cage underneath, you can see it when I move the vertices. That cage seems to be unselectable as well: http://www.student.cs.uwaterloo.ca/~...lems_zoom2.jpg If anyone knows how to fix this, your help is greatly appreciated. I've pretty much stopped all modeling trying to find out how to fix this. Thanks |
ive run into this problem as well.
although im not sure what triggers it from my expirence the only time it happens is when i go back and forth using ctrl+z a lot of times it eventually glitches. but ive almost never been able to fix it, im usually lucky and can undo past where it started or reload the scene file. cant tell you how to manually fix it other than be careful and save a lot. if your scared its gonna happen again, maybe try convert to polys, then duplicate the object and delete the old one and work with the new fresh one |
Hey dudes
Okay this can happen occasionally with SDs but dont panic its not major. Usually its best to re convert thru the menu instead of ctrl_z all the time (lazy) Put a shortcut on a shelf for conversion to and from SD. Okay back to the problem, go to the hypergraph and select the mesh and show the upstream and down stream connections. You will have an extra poly node in there that needs to be deleted. Also you may have SD blind data nodes in there as well which is basically history of the sd, just delete those, that should rectify the prob Jay |
YEAH!
thanks jay, that worked perfectly! now I get back to modeling! |
Cool no probs
