Hi,
not sure yet if it could be a bug, but I'm running into some trouble with shading normals.
In Blender, I either set my model's shading to Smooth or to Flat, but the smooth shading in corona doesn't seem to take into account the auto-smooth setting of the geometry, so unless I model some supporting edges around all hard edges of my model, I get smoothing across all the edges of my model, regardless of their angle.
Did anyone else run into this? Is there some setting I might be missing?
