[Radiance-general] smooth on meshes

[Ignacio Munarriz]

Hi all, i'm enjoying wit a 3dsmax2mesh converter, but i've got some 
problems in the second stage (first stage vertexs, second stage 
normals), i've got obj2mesh as reference and using cvtri function to 
create the mesh faces , but an artifact has appeared in the contour line 
between light and shadow in some objects like spheres as in 
www.aisarquitectura.com/img/sphere.jpg , i think i've seen something 
similar before in radiance docs or list, but now i dont remember where, 
any help?
