[SOLVED] Some help with creating custom geometry

I’m having some trouble wrapping my head around how to make custom meshes in Urho. I took the DynamicGeometry sample as the base and I’m trying to do just a simple quad using a custom mesh. So two triangles. Shouldn’t be too hard, now should it… But for some reason I end up getting very strange results.
What I currently have is one triangle on one side and then on the other side I have one line (see screenshots).

And this is my vertex data and indices:

    float vertexData_[] {
        // Position             Normal
        -0.5f, -0.5f,  0.5f,     0.0f,  0.0f,  1.0f,
        -0.5f,  0.5f,  0.5f,     0.0f,  0.0f,  1.0f,
         0.5f, -0.5f,  0.5f,     0.0f,  0.0f,  1.0f,
         0.5f,  0.5f,  0.5f,     0.0f,  0.0f,  1.0f

    unsigned short indexData_[] {
        0, 1, 2,
        2, 1, 3

And finally the geometry is created like this:

geom->SetVertexBuffer(0, vb);
geom->SetDrawRange(TRIANGLE_STRIP, 0, 4);

The initialization of vb and ib is pretty much exactly as in the sample.

I know there’s probably some really really simple explanation for this, but I keep tripping up with these vertex/index definitions with custom meshes, no matter what engine or language I’m using.

Ugh… Stupid me. When I changed the type from TRIANGLE_LIST to TRIANGLE_STRIP I didn’t realize that I naturally have to adjust the sizes to compensate the different type. So geom->SetDrawRange(TRIANGLE_STRIP, 0, 6) is correct as I have 6 indices… Stupid, stupid, stupid… It works now…
