Setting Up And Using Image Planes
This tutorial will teach you how to use image planes to display your reference images in the Maya interface.
Step one - First you're going to have to open the outliner. Go to window>outliner.
- Select the camera you want to use (to decide, the top camera will
project an image downwards, side will project an image from the side,
and front will project the image from front, or head-on). For this
we're going to use side.
Setting Up The Image Plane Attributes
Step one - The first thing you need is to assign an image to it.
Roll down in the attributes editor until you find image name. Click the
folder icon. This will open a file browser that will let you locate the
reference image you were using.
Center - There are three attributes here. These are the image planes X, Y, and Z coordinates.
Using Multiple Image planes
The reason you would need to use more than one image plane is if you have more than one reference image. Example: you have a top, a side, and a front reference image . First thing you would do is load the image planes in the approrpiate cameras. Then use the height and center attribute, to line then all together. Remember you want to line them up by the image on the image plane, not the image plane itself.
Using Image Planes With Layers
While modeling, it's easy to accidently select the
image plane instead of the object that you wanted to select. Since in
most cases you don't want to select the image plane, you can use a
layer to restrict its selection.
