Are you able to share a sample file so we can take a look at this?
Hi, guys! The general idea is to distribute shingles along the curved wall evenly with a shift on every other row and adjusted angle as we go from bottom to top (see images below).
So far we've tryed Forest on surface, Railclone along splines and Corona Scatter on surface. Last one gave the best results but still not quite there yet. My idea is that simplyfing geometry would help but we still need to keep that curve and the shingles are going crazy on corners and closer to bottom. Same goes with Forest. And regarding Railclone we're not quite shure where to go as it is the one we're least familiar with).
I'm also attaching the examples and the file. So maybe you can help us in which direction should we go to achieve the desired result.
