Ok, I've had this problem since I started with Maya but never bothered to ask about it since my very limited use of NURBS. See the attached picture. How do I get the texture to rotate so that the pupil is at the top of the sphere? I've tried changing all the settings of the place2DTexture node without any luck, and the "interactive placement" is totally crazy; it makes strange curves and I have NO control over it.

Use the transform manipulators tool to reset the spheres pole vecter along X or Z depending upon which way they need to face.

do a projection rather than 2d. This way it wont try and spread itself along the diffevernt UV lengths of the objects.

I think if you go the projection route, you'll want to parent the projector node (term?) to the sphere to keep it in the right spot.

projection mapping is the best way to do an eye.

1/ set up the geometry (make sure the poles are facing outwards, in the direction you want the eye to look)

2/create your material, go to color- click the checkered map box, choose File AS PROJECTION and load up your image.

***ok projection mapping in hardware rendering doesn't always come out perfect, so you have to work with ipr render to see the results***

3/ in the workspace in the hypershade, locate the 3d projection node within the texture node itself, make sure it set as planar projection then bang the interactive placement button

4/ resize, scale and translate (rotate if you have to but you shouldnt need to if you've set up the geometry correctly) to have the projection facing forward infront of the geomtry. (see attached image)

(keep eye on poles!)

oh in answer to mhcannon's post- if its going to be animated, i would simply just set a reference point for the texture and the object rather than parenting it.- another option is just group everything into one.

Also, for a more realisitic eye you may want to use two spheres. Check this link for a great example/tutorial: https://www.andrew-whitehurst.net/eyeTut.html

CG eyes

hmm...or perhaps the quite famous Krishnamurti Costa's tutorial for modeling user added image

and painting of the eye

nurbs eye: mapping

another good place to go for learning how to make an eye
https://users.tinyworld.co.uk/steven_...tic_Eye_01.htm

but I ended up making mine into a poly model... got stuck on the mapping of nurbs bit. how do you do that?

I couldn't seem to find any real explanation as to how mapping worked with nurbs. Cung seemed to give a good explanation there. I hope it works.

I'm going to try krishnamurti's eye tut and see if I can figure out planar/spherical mapping in nurbs. it looks like a good tut.
