Sampling positions from UV map using uvsample()

[konstantin magnus]

I am trying to place a point on a uv-unwrapped mesh based on its UV coordinates interpolated position and normals using uvsample().

float uv_x = chf('uv_x');
float uv_y = chf('uv_y');
vector uv_pos = set(uv_x, uv_y, 0);

@P = uvsample(1, "P", "uv", uv_pos);
@N = uvsample(1, "N", "uv", uv_pos);

While this kind of works, it unfortunately jumps from one row to another instead of smoothly running across the surface. Is this a bug or my fault?

I reviewed your file and I don't experience any jumping using H16.5.359. It moves smoothly for me.

Hi Atom, thanks for checking! I will update to the latest build then.
