How to realize the effect of Transparent in samples\07-Shading-Models

[qpmg]

In the seventh example, how to implement Transparent? I use blender to make the model transparent, but it is still an opaque object after import.
Thank you!

You need to add this line to your egg file:
<Scalar> emitr { 2 }
