problem with new track

[monaco98]

Hi everyone getting there with a track iam working on. have made it trough all the steps and got it in to KRP and work reasonable. a few things to fix up. but there are 2 thing i cant figure out yet how to remove or hide. I have 3 objects sticking up around the track they look like a board they are named in 3dmax as sectors and xfinish. not sure what to do with them if to delete them or if they meed to be there how to hide them. i have attached a picture to show the problem..   the second one is with some of my tire barriers they have a grey shape of them i have attached a picture of that as well if any one has an idea on how to remoe them.

which tirewalls u use? tried with other tirewalls?

[monaco98]

not sure how the grass got on there but if i zoomed in on 3dsmax on the tyres then there is a small triangle on top of them, if i delete it then the grass goes away. problem fixed. not sure how or why it is there but is now gone.
thanks for all help.
