normals missbehaving?!

Hi- the normals in one of my meshes are all pointed horizontally- what happened? Also when you try subdivide smooth and fractal the new vertices are all over the place. I made the mesh be converting from anurbs surface if that helps?
Anyone know whats wrong?

when you subdiv fractal, the vertices that are inserted (because of the subdivide) should be all over the place.

just look at the definition of “fractal”:

A geometric pattern that is repeated at ever smaller scales to produce irregular shapes and surfaces that cannot be represented by classical geometry. Fractals are used especially in computer modeling of irregular patterns and structures in nature.

(taken from <www.dictionary.com>)

this means that the vertices will be placed randomly, so some faces might end up horizontal to your view. this might cause the normals to be seen as horizontal…

but im not exactly sure what you mean by a “horizontal normal”

a screen shot would be nice

sorry for not beeing clear enough heres a screenshot

notice how all the normals are completely horizontal and quite parallel

umm… i’m not quite sure what could cause that, but you can just recalculate your normals outward using [Cntrl+N] (in edit mode with your vertices selected)

i hope this helps

I tried that… nothing happeded
Also i just tried rotating the mesh- and somehow all the normals just keep pointing to the left…

oddly enough if you join it to a new mesh with proper normals evrything is alrite… o well thx for the help anyway

Happened before. Run the Cleanup Mesh script. Manifold mesh could do things like that to your normals.
