What you did

Generate a Mesh with a single triangle, using render2 and pbr2.

A snippet can be seen here.

    vertices.push([0.0, 0.0, 0.0]);
    vertices.push([50.0, 0.0, 0.0]);
    vertices.push([0.0, 100.0, 0.0]);
    indices.push(0);
    indices.push(1);
    indices.push(2);

Using a camera with the following transform to look at it:

Transform::from_xyz(0.0, 30.0, 100.0).looking_at(Vec3::new(0.0, 0.0, 0.0), Vec3::Y),

What you expected to happen

I expected the triangle to be perpendicular to the X,Z plane and having a face towards +Z. Like so:

What actually happened

The triangle is positioned flatly on the X,Z plane facing towards +Y. Like so:
