I now am working on a addon for generating squama ,(I don’t know if I name it correctly though)
it will generates sample objects on anoter object’s surface,you can effect the derection of sample objects by one or more splines ,also you can define the density by vertex group.
It’ still WIP I have realse the file below for testing;
there are some missing features that I am working on.
1:no uv support yet(later will support uv).
2:the size of squama is not support vertex group yet.
