Basic Auto UVs for Power Extrude
Posted: 25 Jan 2018, 15:45
Hi guys,
I want to share a very basic UV generation compound for the Power Extrude plugin ( a huge THANK YOU! to Fabricio Chamon for that tool and in general for the amazing plugins he gave us). I could not find anything for that, so if you are aware of more advanced stuff please let me know.
The UV generator is very basic and works best with the "evenly spaced" algorithms. In order to use it with the "per span" (on path) algorithm use the "compensation factor" slider- it's a very quick and dirty workaround, but I don't have the time right now for a better implementation. It does the (at least primary) job.
You can use it to generate a planar projection for open meshes, like ribbons, low poly hair and such. You can also use a cylindrical projection for closed meshes ( that corrects the UVs on seams), but for open meshes I would use the other one, as it is mush quicker. As for some basic UV manipulation of the UVs, translation, scaling and spiraling (skewing) are implemented.
I developed the compound explicitly for Power Extrude, so I used the nomenclature of this specific plugin. I guess it could easily be extended for any parametric mesh.
Credits: The plugin is an adaptation of the factory shipped "generate 3d grid" ( for the planar projection) as well as on the example from the scene Modeling Cylinder (for the cylindrical one).
I hope it will be of use for somebody. I didn't implement any UVs for the caps, as those are really easy to do in a click manually.
P.S. Don't forget to choose the right projection in the render tree.
