I just wanted to recreate the “view align” function in uvmap() modifier.
So here is my atempt :
(
delete objects
obj = sphere()
select obj
max modify mode
addmodifier obj (uvwmap())
modo = obj.modifiers[#uvwmap]
objTM = obj.objecttransform
modTM = (getModContextTM obj modo)
viewTM = inverse (getViewTM())
viewTM.row3 = -viewTM.row3
newModTM = viewTM
newModTM.row4 = obj.center
modo.gizmo.transform = newModTM * modTM * (inverse objTM)
)
Problem is the gizmo is not oriented to the right direction (Z/up).
What did I miss ?

I ended up with alignement method from mxs help “How do I align uvw_modifier’s gizmo to a selected face ?” :

(

obj = sphere()
select obj
max modify mode
addmodifier obj (uvwmap())
modo = obj.modifiers[#uvwmap]
viewDir = (inverse (getViewTM())).row3
faceNormal = -viewDir
worldUpVector = [0,0,1]
rightVector = normalize (cross worldUpVector faceNormal)
upVector = normalize ( cross rightVector faceNormal )
theMatrix = matrix3 rightVector upVector faceNormal [0,0,0]
modo.gizmo.transform = theMatrix
)
