To run this track so you can see all the walls, and track pieces at once, 
make sure the 1st 6 lines on your metal.ini file (which is in your system 
folder, under the evo2 main folder open it with notepad)  The 1st six
lines need to be like so:

_________________________________________________________________________

; .INI file for Metal Crush 4

[Graphics]
gBigObjectVis=65
gBigGroundVis=80
bigVisFlag=1
useBumpMappedWater=1

_________________________________________________________________________

It may cause slower systems to lag, but it doesn't for me and I dont have the 
best PC in the world, o and one more thing, ENJOY!!
