Introduction to Maya - Modeling Fundamentals Vol 1
This course will look at the fundamentals of modeling in Maya with an emphasis on creating good topology. We'll look at what makes a good model in Maya and why objects are modeled in the way they are.

Polygons always facing camera

Hi,

My problem is almost strange, and I don't know if I can explain myself very well..

What i have: curved surface (basically a side surface of a cilinder that don't turns around over 360 degree.. but that is almost unfolded)

What I whant: each polygon that compose the curved surface must always have his normal on the camera side (but mantaining his normals propertis..).

So, for example, if I have a plane and a camera that turns around it, the normal of that plane must reverse each time the camera turn on the "back" of the plane so I can see the shaded face instead of the "invisible" back of the same face.

I haven't mentioned that I have double sided disabled, and I don't whant enable it because this doesn't solve my problem with normals direction.

Thanks for any help.

(And apologize for my creepy english)

you can simply extrude faces a bit.

You could try aim constraining the geometry to the camera. You can even create a locator, parent it to the geometry and then aim constrain the camera to the locator so the camera and geometry are always looking at each other.
