I have created two Meshes by adding triangular facets’ data. These meshes are initially in same plane and represent a sheet of paper. First mesh represents top side of the paper, and the second one represents the back side. I have set backculling true for both the meshes.
Now, these two messhes exactly overlap, but have opposite normals.
When I fold this paper by 180 degrees (let’s say mid-line) i see an interference pattern.
After the fold, stack ideally is like:
top-> back facets normal up -> front facets normal down-> front facets normal up -> back facets normal down
all these facets are in the same plan (overlap).
How do I resolve this interference pattern? Ideally, only backside should be visible now as there is not transparency.
