I noticed this issue a while back. I have simple planes for emissive materials. I have visible to camera off and 2 sided off.
I get different results if I show plane from above and below - From above the plane is still visible - surely this is not correct?
The plane or the shadow of the plane?
The plane itself... This also happened in 4.3 - I logged the issue back then.
Turn on "two-sided" and it will be invisible.
I appreciate that - is that how it has been designed ?
If I was one sided and invisible then this is not possible when viewed from above?
Thanks for your help - I appreciate this might seem like a small issue but I am just trying to understand functionality
It's not so much how KS is designed but more along the lines of how polygons work. Polygons have face normals, each normal has a front and back so even if you say two sides off, you are just saying don't use both sides, just use one side instead. I assume that by still using one side that it overrides the invisibility as you are requesting one side to remain active.
