…
is there for any technical or artistic reason a solid argument for using the layered material approach with the normal map effect in the mask channel VS using 2 normal materials and apply them to front back via material tag?
thx for any info what is the better way to achieve a good two sided material 
best, bs
ok, so technically speaking it makes no difference?

It’d be nice to consider this as feature request, since it appears to be native to Corona in Max (e.g. [“Easy double sided decals…”](https://forum.corona-renderer.com/ Easy double sided decals... #msg225976))
