Stock Race 07 vs "Race ReMaster" Mod: Ghosts?

[newbert]

Now that I have the excellent "Race ReMaster" mod to run, I have only one puzzling question about it:

In Time Attack, how do I get the "opponent" (ie - my best lap) to appear transparent ( as a ghost)? The opponent is transparent (a ghost) in stock Race 07, but it's solid in Race ReMaster. This blocks the view of the track when you fall behind a bit.

As far as I can tell, I have all settings the same between my Race 07 install and my Race ReMaster install (but I certainly could have missed something).

Can anyone help me out with getting the "ghost" activated in Time Attack in Race ReMaster?

Thanks!
