GT2 - Surface Types Demo (+bonus)

[@DatShepTho]

Ah yes, I remember when I stepped on some _INVALID SURFACE_ once

I actually love the rumble strip sound. It sounds so rubbery :)

These invalid surfaces have meme track potential

[@boomkittyFX]

what if you code a whole track to be invalid surface, would it crash?

[@submaniac93]

I've thought about it, but it's an impossible task with how many individual polygons i'd have to find and change. Doubt it would crash,it'd probably just be a game of pinball

[@laharl2k]

I never noticed the grass bumpiness was an "effect", i always thought it was caused by the geometry of the track in that section. I suppose theres a "bumpiness" variable that depending on the level its set to it randomly adds or substract acceleration to the car in some direction (not forward) depending on your speed, thats why the invalid surface types cause you to go flying backwards because the values are garbage though in theory it should also be possible to send you flying upwards if my theory is correct.

[@submaniac93]

It sounds plausible, sadly that behavior as far as i currently know is hardcoded, because nothing of the sort is in the surface data. 8n fact the only thing in the surface data is some kind of grip modifier. The entire file is 8 bytes long lmao

[@laharl2k]

@@submaniac93 Did they use the grip modifier anywhere? I imagine they would use something like that to fine tune each part of the tracks to convey different reaction types to each type of surface, say tarmac vs concreate or gravel. I guess they kept them separate to save memory or something. For what you describe i assume the terrain effect has no effect in the grip. (i cant notice grass doing much except for bumping the car around) May i suggest trying setting it to grass and maxing the grip mod variable? (if it works) or vice versa, normal road with 0 grip, for an "ice level" like experience?

[@submaniac93]

Those are global parameters, so they're never altered. I could only determine that they can increase the grip, not reduce, but in order to make them icy, it's the tire compounds that need editing.

[@darkmagicians62]

Mod idea: You could pick the Calibra Touring Car body and make the road Calibra 2.0 16v, changing its body and specs to the 2.0 16-valve model

[@submaniac93]

That's an idea but in practice it's nearly impossible. There's too much work to do with the current ways. It would need an entirely new body to make right.

[@NDR008]

Thanks! :)

[@PettyWingman]

No. 5 causes almost no speed loss, so sometimes it could be useful...

[@submaniac93]

The data for each surface points at 0 being at 100, 1-5-6 at 80, and 2-3-4 at 60. Increasing any of them increases the overall grip on the surface, however putting them at 0 barely reduces grip. So take those numbers however you want. One thing for sure, Asphalt is the only surface that's not doing anything to your car when you're on it.

[@PettyWingman]

submaniac93 Thank you for the detail info :)

[@karelpipa]

@@submaniac93 so what does the packed dirt on Laguna Seca to your speed and grip?

[@submaniac93]

@@karelpipa speed and grip are slightly reduced compared to asphalt, but not by much

[@reinaldosoraoktavian960]

Sorry can u make a code to enable ghost on replay just like gran turismo 4

[@Steventhe2nd]

you think that #7 could've been wet weather surface????

[@submaniac93]

No, 7 is nothing, just zeroes in the file. It's just that i wanted to show the effect that had

[@jean012mx6]

Ojalá ubiera un mod que de más REALISMO

[@submaniac93]

Small oopsie for value 7 where i forgot to change it at first :p

[@anaclarafraga758]

submanic93 você sabe me dizer porque os códigos do Gran turismo 2 disco 2 SCPS-10117 não funcionam tentei no cheat engine so que eu não sei mexer mas você pode me ajudar com os códigos e mas uma qousa que eu sei se você trocar os arquivos de de certas versões do Gran turismo 2 você obterá tracks aleatórios e até engraçado só que são tracks inacessíveis e não pressisa de código se for eu ate posso mandar um vídeo mostrando esses tracks alguns sao parecidos com dos gran turismo 3

[@tachyon3512]

what would happen if you made the entire track the 8+ surface type?

[@submaniac93]

Good question, I assume i'd evenually be sent flying either up or out of bounds.

[@laharl2k]

@@submaniac93 i can smell obstacles course for silly drift chalenges maybe? xD

[@submaniac93]

@@laharl2k Nah it's diffucult and needlessly long to edit an entire track. Each track is divided into dozens of parts. The blue area in the video is the entire length of the chunk i was editing and it includes the grass, wall, and the scenery as well. It would take a month to do something major to a track that way.

[@jean012mx6]

Es un mod muy interesante estará para epsxpe?
