I added effects.wdl to my level, and applied the envcube and envmirror effects to models. the skin has 24but tga with alpha channel -- with envcube I cannot selectively show the reflection; its either all env mapped or partially transparent. With envmirror its partially transparent or all white. What is the difference between cube and mirror?

How do I set up my skins and the script so I can have some metal on the car reflect the environment and some showing the vehicle paint?
