    Selecting tools.

    This important video covers the two-edge selection mechanism: the Edge Loop Tool and the Shortest Edge Path Tool.



    Seams: cutting and welding.

    It covers the different ways to mark seams (separate polygons of the model). Among others things, this shows the two welding modes: "Weld" and "Mutual Weld" that are complimentary and useful in different scenarios.



    Unfold : The main UNFOLD3D algorithm

    This defines the set on which the Unfold command is applied. It also covers the overlapping "Prevent" option. (prevent overlapping sounds better)



    Optimize: Reduce the stretching

    This defines the set on which the Optimize command is applied. It also shows the Optimize Brush tool, and covers the "Angle vs Distance" conservation factor.



    Workflow: isolate islands helpers

    This shows two different workflows when working on models composed of several islands. Among other things, "Auto Isolate" helps you by hiding automatically the other islands that are flat ones.



    Transform: move / scale / rotate selection set

    This covers all tools and options in the "Tranform Panel". It shows that the "TAB key" displays "Gizmo" even in other edition modes apart from the Translate / Rotate / Scale modes. This is particularly useful when you are in a selection phase and you just want to move an island or a point quickly, for example.



    Proportional edit: softly propagate the transformation over a distance from the selection set.

    This covers all of the tools of the proportional edition mode. Moving a single point, or even a set of points creates distortion around the selection set. Activating this option reduces that distortion.


    Real Time Optimize: Propagate the transformation over the entire surface of the island.

    Even when the proportional mode is activated, when transforming or dragging, some distortion can appear. When the Real Time Optimize (RTO) engine is enabled, it spreads the transformation effect over the whole island, and this creates less distortion. Note that in "Drag Mode", enabling the RTO often helps to remove mesh mangling.


    Density Map: Paint area where you want more or less texel resolution.

    Sometimes you have zones that need more definition because you paint a lot of detail on them. Painting with a factor 3, for example, will make the area bigger, so you will have more pixels to define your texture details.


    Verticals and Horizontal constraints.

    When you need some edges to be exactly vertical or horizontal, you can apply that property to the edge selection set, then, when you use Optimize, it will take those constraints into account.


    Topological copy

    When you have some islands that have the same polygon structure (same topology), you can use the option to copy the edge selection from one island to another. If you then cut the islands, you will obtain a set of islands that have the same cut topology. You can also copy the coordinates from one island to others.
