Hello Guys !
I have this tool in mind since a long time !

The idea is to be able to generate trim on the mesh from a selected edge.

The artist will pick a Texture ID and a edges and it will generate the trim + uvs at the correct Pixel ratio.

as an example the Cryengine Normal Decals : [docs.cryengine.com]
(Images are not from my tool it's more that i would like to achieve )

First i want to know if I'm able to Create Uvs / Meshs based on Input Texture ID.

The artist will provide a Bounding id or an mask ID to help me select the different Trims.
I'm using a plane and sample each "pixels" ( point in my Wrangle). then I isolate colors and create geo and Uvs.

At the end I will create the Geo and the Uvs with a selection from an input mesh. But I want to make sure I will be able to do get the textures information before starting developing something

If I understadn correctly Python state at a point. I will take a look for a preview + selection in viewport with a click.

So i only have on side of my trim and i need to fix some issue to do the other side, and then the uvs.

The tricky part here was to order the selected point and sort then, and then find the neighbourghs points and define who's on right who's on left to be able to re-create the topology.

I'm still struggling if no neighbourgs are founds,with Ngon and with loops. But on step at as time !

Creating game artwork is definitely no walk in the park, unlike playing at Winward Casino where all you have to do is sit back and enjoy the games. Designing game graphics requires a combination of artistic skill, technical knowledge, and creativity. I recommend winwardcasino.net where you can have great fun and take your mind off creating game art. From conceptualizing characters and environments to actually bringing them to life with software tools like Photoshop or Illustrator, it takes a lot of time and effort to produce high-quality game visuals.While playing games at Winward Casino may be relaxing and entertaining, creating the artwork that goes into those games is a whole different ballgame that demands dedication and talent.
