Stencil Shadow with open mesh? - 01/16/10 00:24

Hi..

I�ve a little problem. I got a Link 3DS model (Zelda) from a friend. But the Model has 356 Open Meshs. That�s becaue everything is made as single part.

Now i need stencil Shadow in the project.. but with open meshs, it looks aweful...

Any way to fix that (without remodeling everything)?

Edit: tried with Unitx3D and it worked.. what�s with A7?

from the manual:

Quote:

Stencil shadows require models consisting of closed meshes. The meshes must have no holes, and no polygons must intersect each other or touch each other with their flat side. Otherwise rendering errors (dark lines projecting from the model to the shadow) can be visible. In a closed mesh, every edge is shared by exactly two triangles. If the model's mesh is not closed, create a closed mesh LOD model or shadow model for shadow casting. The MED mesh tester can be used for determining whether a mesh is closed or not.

I think, you have two choices:
- close the meshes
- try other shadowing technique (decal shadow, for example)

Can't you just select the whole mesh and merge the vertices using MED?

no, then it will merge all vertices to one vertice

@ali,
that is weld, not merge.

i can�t, becasue some of the vertexes overlap with merging.. and than the skinning is destroyd ^^ ( tried it with link and Tail )

If you can't close the mesh up, then you have no choice but to use a different kind of shadow, like a z-buffer shadow or a decal.

When I export my model to 3DS, the mesh gets opened. But, when I export the model to FBX, the mesh is just fine. Then, simply export to FBX.

tried fbx too.
still open

well you could use a low poly closed mesh as an LOD and let that draw the shadows, would have to have the same anims though... not sure how it'd work but it should

duplicate the model, invert poly's, merge polygons together... doubles the poly's, but closes your mesh

First check why your model has so many open meshes. It is unusual for professional models to have open meshes.

If its meshes are really broken and can't be fixed, create LOD models. With the Pro Edition, MED does this automatically, with lower editions you have to create such a model manually. Make sure that the meshes of the LOD models are closed.
