Automatically adjust UV mapping

Post by Harald-RS »

Hello Oleg,

I think I'm not the only one who has this wish.

Would it be possible for you to optimize Z-Mod 3 so that when you move a 3D model with a vertex, the mapping automatically adjusts.

So that nothing shifts in terms of the skin.

Hello.
The task "to move UV data for the vertex that you move in 3D space" might have multiple solutions or might have no solution at all, depending on what is the uv mapping on neighbor polygons. two polygons might have different layout on UV and instruct the vertex to move it's UV in a very different directions.

Yet this task might have a good solution in quite many cases (in particular when UV is uniform / mapped from viewport with no extra alternations), but even in this case the vertex movement might be out of "surface" (toward/backward the) plane. This scenario does not give the proper solution on "where the UV should actually move" in such a case.

Strange, why can Blender do that? If you move objects in wireframe mode (I think it's vertex), the mapping adjusts automatically.

It would be a real shame if Z-Mod couldn't do what a free program can.

Yup, Blender can do quite many things that ZModeler doesn't. May be cause Blender is not that "free" as you might think. It has a 1.5mil euros in salary for developers and there are 150+ active developers/contributors behind the code.

Meanwhile, how will the UV move for the center vertex in such a figure with the given UV layout?

All I can say is that I saw in a video that the Blender modder simply moved the object in size/length and the mapping adjusted automatically.
