first of all, hi everybody! i didn't see any welcome area (but i could be wrong...) so i introduce myself here!
My name's Bernardo, im from Italy, and i like 3d art and other connected stuff. i try to do something with open source and free programs such as blender. when i saw this sculptris i couldn't believe it! it's really great!!
however now i have a little problem. i made a model in blender and then i exported it as a obj. when i try to import the model in sculptris, whatever options i use, the program crash to the desktop.
I tried to export the simple default cube of blender, and it worked smoothly, so i think the problem is with my model.
before exporting it i tried to apply all the modifiers (i had a mirror and a subsurf) and to set the face as solid, instead of smooth, but sculptris is still crashing.
any idea of which could be the problem?
my system is an i5 750, 4gb ram, gts250 on win7 ultimate 64bit.
i hope to manage to solve this issue because i really would like to use this great program!
PS: sorry if i made some mistake with the language!
I remember previous version of Sculptris needed the imported OBJ to be triangulated, it crashed for me with square faces.
Sculptris has some problem too with some kind of geometry, like for the UVSphere of Blender that Sculptris is unable to display without crashing. The source of the problem was as worstplayer pointed to me in another thread too much faces sharing the same vertices
I guess the problem was too many polygons sharing same vertex. Try deleting tops of the sphere and see if it helps.
It was these vertices (the one on top and the one in the bottom of the UVSphere) that made Sculptris to crash
For that simple object, it was not a problem, so it was easy to fix on the model, but some people may want to import models a bit more complex than a sphere, so deleting a vertices just because it is shared by many faces is not a good solution. On other board i read many mentions of people unable to import their models, certainly because of this kind of geometry.
I hope this crashing problem will be fixed in the future for Sculptris.
I like both. It being in blender might make it more handy for me, with everything being in one place, but only if it provides the same features sculptries has. I have to say that the automatic unwrap in Sculptris is better than blender's, but the painting tools are inferior. In the end i'll use the better tool, doesn't really matter which one it is.
non -manifold faces are defined as more than two faces sharing a single edge. In a clean mesh only two faces can share the same edge. In certain opperations (eg decimation opperations) it may happen that the error occurs.
This is not only a Blender problem.
Just to mention a simple other way to remove all those faces with a single click: Load the mesh to meshlab, Go to menue Filters/Cleaning and Repairing/ Remove Non Manifold Faces. Save as obj (If you do a mesh reduction in Meshlab I suggest always to run that filter before saving the mesh)
