the new corona tile shader as i see it in max forum is more powerful than maxons brick shader, i flow the test there since some time.
but a lot less power full than the TilePro plugin, which is also native Corona compatible (from 3dtools.info).
on a side note: i admid i am not unbiased as i invented TilePro, but i am confident it is the probably unbeaten best tile shader on the planet, on any platform;)
i use it myself daily in any project.
