Hi, everyone.

I’m workin in an application that generate procedurally some geometries and the user can select the mesh triangles for move or delete. The way I implemented this was making a class that “clone” the mesh, generating each mesh triangle as a new independent mesh. Well, the complete meshes geometries are always OK, but some of the independent triangles aren’t visible, even using a color material with bothSides=true. I verified that the 3 vertices of each invisible triangle are not co-linear, too. I picked one vertexData example for try to understand:

var vertices:Vector.<Number> = Vector.<Number>([-100,225,173,100,225,xx,0,225,0]);

The variable xx, when between 0 and 172, produces an invisible triangle.

I tried with SubGeometry and with CompactSubGeometry, with the same results.

Can anyone tell me if this is a bug and if is there any fix for this? I,m using away 4.1 and i haven’t tried yet whith 4.0.

Thanks for any help.
