Cheers Paulo I overlooked the HD feature, and I assumed you needed to do this when creating a DAT, and not when "Creating Track From DAT".
But for me It smooths the inside of the lines but not the outside, If that has anything to do with the dat I'm going to have to hassle gildoorf, ( I can't make dats)
I know lo2k is developing this area, so maybe that's to come.
It's not much work in max to fix this tho' I'm just a stickler for precision
Oh.....the mesh I couldn't see had "track" in the name, I just renamed it and it shows fine now.
thx for the info
