2 sided material c4d front back materail tag vs layered material normal map mask

[bs]

...

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

I guess it comes down to work flow and ease of use. For me personally, I tend to use the layered material approach.

ok, so technically speaking it makes no difference?
