Quote - ...I'm wondering if the use of the close weights-generated average for the normal might help for a second ray-casting pass....

I'm not sure I understand the question... the ray-casting code (the snippet that I posted) is averaging the normals of the passed in list of close vertices and using THAT as the ray direction for the ray-cast... and yet, it sounds like that's what you're asking about / suggesting??

Or am I misunderstanding?
