[SOLVED] - Computing Normals From Verts and Triangles

[MackeyK24]

Can someone please help me out with computing normals from just the verts and triangles in C# Unity Side. Currently i am using the Unity Mesh object to calculate normals like so: 

Mesh mesh = new Mesh();
mesh.name = "sceneNavigationMesh";
mesh.vertices = triangulatedNavMesh.vertices;
mesh.triangles = triangulatedNavMesh.indices;
mesh.RecalculateNormals();

 But the Mesh object is limited to 65000 verts... So i am going to need to manually calculate normals... But don't know how. What are the Magic Formulas for calculating the normals?

Again... Any help would be awesome

Here we are:

I tried the ComputeNormal code (both in babylon javascript and from C# exporter)... The verts are listed in debug layer but does not show up... It looks like it reversed or something... Because the vertex data is coming string from unity raw heights  maybe we have to flip the normals or something like like... Can (AND HOW) would i flip normals (if thats even the problem)

Flipping a vector means multiplying it by -1 (on each component I mean)
