  1. Sampling positions from UV map using uvsample()

    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? pos_from_uv.hipnc
