Hash Fellow robcat2075 Posted April 23, 2017 Hash Fellow Share Posted April 23, 2017 Surface Properties have two rarely noticed options: Average Normals, which when ON enables...Normal Weight 0% -100% This seems to control how the surface normal is interpolated from one spline to the next across a patch which affects shading and reflection results. Notice the difference in reflections and specular highlights in these three images. From left to right... Normal Weight 0%, 50 %, 100%OFF and 0% is the A:M default but ON and 50% is the result most like the intended spline shape and will give you smoothest results for most models. 1 Quote Link to comment Share on other sites More sharing options...
Guest Posted April 23, 2017 Share Posted April 23, 2017 If I'm not mistaken,the long ago "Porcelain" material (so named by Hash since it reduced creases in face models thus supposedly giving them the look of porcelain dolls) set normal weights at 100%?

Hash Fellow robcat2075 Posted April 23, 2017 Author Hash Fellow Share Posted April 23, 2017 The porcelain had a parameter but i don't think the numbers corresponded exactly with this one. 50% gets the smoothest patches in this scheme. This is an overhead view of a 4-spline dome... Quote Link to comment Share on other sites More sharing options...
strato Posted May 11, 2017 Share Posted May 11, 2017 Porcelain works really good in Version 12 and allows a smooth render for 3 point and 5 point patches at 100%. It changed in V 13 with the model format change. From V13 on 50% of Porcelain, like the Average Normals option at 50%, produces the smoothest surface in my experience, but not as good as V12.
