Hi,
My custom geometry is plain. On front side it renders, but when I rotate
it that only back side is visible then plain doesn't painted. What is
the practice in such situation? I tried to defined back side in the
geometry with the same positions but with normals looked at back. And
this doesn't help. I need a plain that will be rendered on both sides.
Whether a triangle is considered forward or backward facing is
determined by the winding order of the vertices, so you also need to
swap the ordering on your other face.
Alternatively, disable the back face culling renderstate in your
material or frame graph. This is enabled by default for performance
reasons but if you explicitly need to see the backfaces this can be
adjusted.
Great, but I can't find how to disable back face culling renderstate in
QPhongMaterial.
