Cube or Box Mapping

Post by LuKz »

Hello Oleg,

I was thinking if it would be possible to put a mapping tool like a cube or box, I really feel the need to do a mapping on pieces that require equal sides with texture continuity.

Thanks.

May you show an example of the object you would like to be mapped with box-mapping, its current uv mapping (the one you've created manually) and how it should look in result?

I doubt the box mapping will do the suitable result, as it maps polygons with respect to their surface normal orientation (most straightforward direction matching the cube facet). In particular, any non-ordinary surface will likely to get some polygons to be mapped to one facet, and neighbor polygons to another facet. As a result, you will loose "texture continuity". For example, if you need to map some arbitrary tiled texture onto surface (fabric, leather, textile pattern), these joints/seams of front-mapped and, say, top-mapped polygons will be visible.

Hello Oleg,

I'm sorry for the delay, I didn't know the response would come so quickly, I was impressed with the speed and thank you for your attention. Here in Brazil, unfortunately, we sometimes wait days for a response.

Anyway, I took the photos of the example as I would like, the mapping would not need to be perfectly continuous, but it could not stretch in parts that the viewport does not show and it will have this dragged appearance without the need to detach and map parts by parts , because there are models that are impossible to apply detach due to many vertices and also because of the time it would take to select the correct face.

These two images are what it looks like

And the image below is how I would like it to look.

I would recommend an "Unwrap" mapping mode for such a task. This will give the desired mapping layout for repeating pattern.

this one has an explanation on how unwrap is used. In particular, it has an example of torus/donut unwrap mapping in the end.

Oh, Thanks Oleg!

This tutorial helped me and will help me a lot.
