Which element to bend UV mapping?

Is there an element that when bent will also bend the material mapping?

I tried slabs, walls and beams but the top part of the element is always mapped without taking into account the bend:

Its not possible with the same texture, because You would get different block-sizes.

In the world of work, these types of mosaic are supplied in larger prefabricated areas on lengths of fabric, where the mosaic is glued onto it in a finished rectangular shape.

like this:

The only pattern that such a curved mosaic could satisfactorily represent would be a photograph of a real arched mosaic

Another Way would be to program a real 3D-GDL pattern, but this would be very performance guzzling for the computer like i made for arches. Similar to this: https://bimcomponents.com/GSM/Details/23429, but with much smaller blocks..

I could live with the different block sizes as the mosaic will be under water

The impression of the mosaic following the bend outweighs the disadvantage of the mosaic being slightly smaller (for my use at least)

And yes the mosaics come in sheets, but to do shapes like this they are usually cut into strips and laid to follow the bend, or if the bend is tight the mosaics are pulled off the sheet and shaped and placed individually

I'm surprised that with all the available elements none of them have mapping that follows the shape when bent. Will need to make a separate texture as suggested

an other Answer would be the mentioned methode above. But the computer will have to work for it much more than i would suggest for a thing under water..

It took me about an hour or so - and a life full of GDL-Learning bevore - smile

an update to make it possible to get a full circle and shake individual blocks:
