Convert height map to normal map without HeightToNormalSmooth

[BananableOffense]

The only way to perfectly solve procedural normals in my experience is mathematically.

Vertex normals after world position offset

Is it possible? Probably yes. It depends on how you’re deforming the mesh. If you’re using math functions, the normal of a curve can be found mathematically also. Here’s a forum post that discusses solving for the normal of a point on a sine wave, for example. https://gamedev.net/forums/topic/551569-finding-the-normal-of-a-point-on-a-sine-wave/551569/ “Sine curve is parameterized as (x,sin(x)). A unit-length tangent is (1,cos(x))/sqrt(1+(cos(x))^2) = (tx,ty). A unit-length normal is (ty,-tx)…

Here’s a thread where I showed the formula for finding the normal of a sine wave and an example material that uses it. Similar steps can be taken with any curve function, although it’ll probably take some light calculus and trigonometry to do with custom functions.
