What do I need to provide in my custom geometry in order to have it display correctly in 2D and Columbus views? Though they are rendered correctly in 3D, all of my geometries are have lighting issues in 2D/Columbus (+z face of my box-like geometries are very dark), and my simple 4 point bounded planes only have one of four points in the correct location, the others are skewed. I’m not sure if I’ve failed to implement something required for these views or if I am somehow not ordering my positions correctly. I currently only create positions, indices, and normals (which are computed using the GeometryPipline.computeNormal() function.) I don’t compute st, tangents or binormals because I don’t know what the st attribute is or how to compute it.
