I’m trying to replicate the output of the max 2009 obj exporter by guruware but I don’t really understand the way they are creating the vertex normal’s.
Apparently it goes trough the vertex twice but skipping some vertex the second time, I can get the first pass correctly with this code
tmpNormArr = #()
for i = 1 to meshObj.numverts do
(
in coordsys local normals = meshop.getFaceRNormals meshObj i
for j = 1 to 3 do
(
n_X = normals[j][1]
n_Y = normals[j][2]
n_Z = normals[j][3]
format "vn % % % \n" n_X n_Y n_Z to:out_file
)
append tmpNormArr normals
)
But I have no idea what the second pass does. Has anyone look at it?
