[rob-bateman]

Steps to reproduce

• open a new blank file
• create a sphere and add to scene with a mesh
• create a new mateiral on the sphere
• create a light picker on the mateiral
• create a directional light on the light picker
• set the azimuth value to 150
• save the awd
• close away builder
• reopen away builder
• load the saved awd file

expected result

There is one directional light at 150 azimuth

actual result

There are two directional lights, one at 150 degrees azimuth and the other at the default zero azimuth. The texture has also changed from using a default texture to using a white texture
