Hi all. I made this object in substance designer, and there it looks good.
But in unreal engine i have some problem with normals.
This texture i put on second uv chanel, and shadows on stones always are in bottom of uv map, but not in bottom in geometry.
as i understand if i use second uv chanel i need to use same specific setap of shader. now i use this. What i need to change?

In the most basic terms, you cannot use the second UV channel for normal maps because of how tangent biases are stored.
This thread contains more information and various workarounds.

If you’re using the default settings from Substance, you need to go into your imported texture in UE4 and check the “flip green channel” flag.
