Hi Bard, that's a really great use of Flow!

For things like the logo there is also a new additional "Projective" mode for Flow which can help for applying an object on to a more localized area on a target rather than wrapping it onto the full surface extent as the normal Flow mode.

To use it, you first need to actually position the object that you want to place and its base plane at the projection angle that you want to use to beam the object on by, so unlike the regular flow the orientation of the base plane is significant for this mode, and the object gets applied on to the target by rays shooting out along the base plane's surface normals and intersecting the target object.

So for example say you want to apply this little star shape on to the revolved surface more like applying a decal and not so much like applying a pattern along the entire surface:




So similar to regular flow, with projective flow you still need a base plane for the object. However in this case the base plane does not need to relate to the full size of the target surface, you can instead place it just framing the object to be deformed with a small margin around it like this:



Then take the object and base plane together and rotate them into the position for what angle you would like them to be projected at. The Transform > Orient tool can be useful for this, or you can use any kind of rotation or placement methods. So for example you would move them into a position like this:



This positioning step is the main difference from regular flow - unlike regular flow the angle of how the plane projects on to the target object is significant with projective flow mode. The relation of the object to the base plane still controls the "water level" of the object on to the target though as well, meaning the deformed object will touch the target object at the same place it touches the base plane.

Then to activate projective mode, there is a checkbox that you enable when you go to pick the target surface:



You need to set that checkbox before picking the target object, and also in projective mode you're able to pick a joined surface as the target instead of just a single surface, and as long as the joined surface is all smooth throughout it is ok for the object to cross surface boundaries on the target in projective mode.

So that generates this kind of result:






Anyway, the nice thing about projective mode is that you don't have to worry about the aspect ratio of the full surface and try to account for that when setting things up, it should be a bit easier to use for cases where you want to apply an object to a more local spot of an object rather than as a full texture.

There's also a "Straight" option that you can set in the last stage for projective mode - this controls the shape of how the deformed object grows out from the target. Without straight it comes off of the target's surface normal, making an offset like result. With straight enabled it comes off along the base plane's surface normal, making it act more like an extrusion in that direction rather than a surface offset.
