Seamless

Seamless targets a spatial join. BMD describes it as mirroring the opposite edge and blending it with the source. This changes edge content; a large object near the boundary can develop visible symmetry or repetition.

The supplied Inspector contains Type with Blend/Merge, Lock with All Sides/Vert/Horiz, and Fraction. The capture selects Blend, All Sides and Fraction 0.05. This is a useful comparison starting point, not a universal guarantee of an invisible seam.

Lock describes how side controls are linked. All Sides and Vert/Horiz should not be read as ready-made switches that process only X or only Y. After switching modes, inspect the controls actually available in your version and recheck both boundaries.

Fraction controls the edge-region proportion. Increase it one step at a time and compare the join against detail retention. The supplied capture alone does not establish the pixel-width formula or the exact Merge mathematics.

For inspection, place a regular Transform after Seamless with Edges set to Wrap. A smaller scale reveals neighboring tiles, and translation exposes the spatial join in motion. Transform Wrap repeats the edges without changing the frame’s physical resolution.

If the source has alpha, inspect it separately from RGB. Hiding a color seam does not establish matching transparency. Check timing separately when looping the source animation; SeamlessLoop addresses that temporal task.
