This knowledge was added a moment ago and deserves it's own thread. Finally a guide of how to use those missing materials.. I quote neteye:
hold your horses, i dont have time to write posts everytime im on the forum.
i never had problems removing one of my tracks tdf file. It seems that (my) race07 just ignores it, you can edit what you want in it, it had no effect. so i dont think that this is a key with the technic. race07 has a file called specialfx.tec in its archives in the locations folder where all materials are specified, which grip they have, bumps etc.
if you had opened the tracks with 3dSimed, you would have seen that its all about material names. the btb materials are not adapted to race07, so only very few of them work (the start/finish lights etc. arent either as you probably know, also because of the lack of adaption). but you can write your one materials in the field, so its quite easy if you know the material names.
first in the specialfx.tec base values are specified, which you easily can overwrite with your gdb file in every track by writing a different value after the variable, which are (with the base values behind):
RoadDryGrip=1.00
RoadWetGrip=0.75
RoadBumpAmp=0.0075
RoadBumpLen=5.0
RumbleDryGrip=0.98
RumbleWetGrip=0.75
RumbleBumpAmp=0.015
RumbleBumpLen=8.0
so we come to material names:
road : the most known oneuses entirely the "road..." variables.
lgroad: drygrip 0.95, wet 0.74, bump amplitude 0.020, wavelength 1.0
b1road: grip from roadvariables, amplitude 0.020, length 5.0, small bumps, has like a washboard effect
b2road: grip from roadvariables, 0.024, length 14.0, bigger and wider apart
b3road: grip from roadvariables, 0.030, length 18.0, much bigger, much wider apart
cutprevention when having paved run offs? just use...
marbles: drygrip 0.5, wet 0.48, small bumps. you already have problem starting without spinning, as the grip is damn low. try for example la source runoff in spa and try getting away after you braked to late
thats it with the tarmacs, so the next are rumblestrips and drains.
rmbl: well known, nothing really new here, except that it uses the rumblevariables from above
drain: same as rumblestrips, but griplevel is way lower: 0.80 dry and 0.60 wet
and lastly, the terrain ones:
gbrm: grassy berms or "flat lowgrip grass", has only griplevels 0.40/0.30, but lesser bumps than the normal grass. also has some resistance which makes you slower, similar to the marbles
gras: grip 0.60/0.40, think i dont have to say much about it, you should know it
grv: graveltrap, 0.70/0.70, about 3 times the resistance of grass, should be known also
bsand: 0.80/0.80, same resistance as graveltrap, but damn thats bumpy, bumpamp 10cm every meter. when i first tested it on a fast built track and ran into it i was shocked and shaken. you also have more problems getting out of it than in the normal graveltrap, despite the more grip.
twall for tirewalls, cwal for cementwalls, grdr for guardrails...
also in this file specified are the other effects like sparks when bottoming out, smoke form tires etc, raineffects, sprayscreen and dirtscreen, stonechips, everything which land on your windscreen
what i just... hate? with this specialfx.tec is... you cant edit it. every track acesses this file, and it is checked everytime you race online, so you will always have online mismatches, as far is i tested it. i tried once to build a snowy racetrack like the trophee andros ones, as a wintersurprise. but its nowhere satisfactory having black rubber lines on a snow texture, or green ones from the grass terrain if your using this one, having no clouds of snow behind the car (or brown ones....). all of that could be done with rfactor tracks, because it supports the tdf files, which is track specific.
so... hopefully this a satisfactory answer for your waiting time...
greetings,
Neteye
