ZitatI'm not a 3D modeling
expert, but isn't it possible to take this model and somehow convert it
to a lower poly model so it fits into train fever?
3 Things
No you can't reduce 500'000 polys to 10'000 without destroying the model or work for ages. It would take less time to make a new model than to try to use this high poly one.
But it also woun't be right to use this model since it is not @FLYNN own work. (Shame on you for that scam).
So this is out of qestion to use that model other than for render pictures.
Good day chaps
