TDU 2 Physics

[Andriy242]

Maybe this has already been asked. I am not sure though but I might as well try.

 

Is it possible to transfer TDU1 physics to TDU2.

If not just transferring the file setup.

 

Why not just decrypt the TDU1 physics setup and copy that into the TDU2 physics setup.

Also edit the tire grip and acceleration linearity, etc.

 

any takers?

[Andreas¹]

It it was as easy as "just decrypting" the physics I think it would have been done already. I'm no programmer but I'd say that the physics are among the deepest buried secrets in any game. I don't think anybody can touch them except for the developers of the game.

well actually tdu1 had a bunch of community made physics editors.

I think the real problem is online verification really even if you figure out how to do it.

[Andreas¹]

Those editors changed the properties of the individual cars. Those still have to answer to the main physics engine of the whole game, which is what I was talking about and I guess the OP as well. I guess you could just copy and paste the physics of each car (i.e. the acceleration, top speed, bhp, etc. etc.) into TDU2 somehow but that wouldn't make it TDU1 as TDU2 has a whole new physics engine that treats those numbers so much different and does different things with them than the physics engine in TDU1.

[Andriy242]

Yea thats what I was talking about. Setting it up so that ther is some suspension travel and the cars can handle better.

 

Would this be any help?
