OMG!

So near 1 month ago I was maling some new models with really cool engines, using realy epic pistons. They was very difficult, so to make it work perfect I spent a lot of time! But then I have some exams in June, so I got a brake for TPT until today....

And now, Im launching TPT, and see, that one little fix in patch broke all my models! This fix made a little thing: Imagine, that we have a piston, some particles on it (for example METL), and wall upside of piston. When piston moves up, it moves particles on it too. BUT! In early versions piston could moves up, until it smash all METL particles in wall (then piston meets wall and stop). METL particles disapears in wall then. It wasnt realistic, but when I was creating my engines, this property was main in my engines, because when we have some oil/gas in engine, and piston moves up - it looks like pistone compress the oil, and it looks like a real 4t engine.

Now when pistone moves up, it can not smash partices in wall, it moves up only until particles on piston meets wall, and then stopes. But!!!! Stop moving only parts of pistones, which have particles on it, which meet wall! Another parts of piston continue moving up, and piston brokes then!

So when oil/gas mix are in engine it becomes moves rapidly into pistone, so some particles can meet wall earlyer, then another, and piston breakes.

My english is not very good, but I hope, you understand me. For example look at this save, which was working perfect, when it was on FP. But now piston fix makes it work incorrect, and engine brakes down (especially, when you press acceleration).

Thanks for idea with absorb wall, but also I need to use standart E-walls as a valves in engine, and they cant absorb particles when closed :(

In this post caps doesnt mean angry crying, it just allocate main in text.
