In aiStandardSurface, we connected the normal map using the aiNormalMap utility.
The problem is that the backface is not rendered when using aiNormalMap.
When bump2d is used, it is rendered normally.
Do you know the solution to this problem?
What the backface means is that it refers to the back side of an object with no thickness.
I'm sorry I can not speak English well.
Have you got "Export Tangents" enabled in the shape Arnold options?
