[SOLVED] strange problem with mesh_wire_base material

[steve3d]

I know this is the new material for various kind of wires shader which makes wires looks better.
but in our scene, we have this wire material applied to a wire object, the material splits the wire objects like screenshot.

 

Then I found this shader seems have face normal limitation. In material editor, you can test this with cube/sphere/docechedron, only sphere with this shader won't split the faces, all other type of geometry always split faces.

 

for a wire object, we only cares about it's rendering, there should be no big difference between using 3-side cylinder or 7-8 side cylinder.

after a few tests, in order to prevent this, I have to make a minimium 7-side cylinder... this will waste too many triangles if we have a complex wire object..

Don't use flat shading for triangles.

Normals must be smoothed.

[steve3d]

it's definitly smooth shading, no any hard edges, or in 3dsmax terms, only one smooth group on this objects

Try to smooth this mesh in the ResourceEditor.
