Unfortunately a voxel engine is poorly suited for rails. The rails wouldn't all be straight - you'd want turns and inclines as well. In order to not look ridiculous, those turns and inclines would need to be gentle, over a long distance, which doesn't line up with the rest of a voxel world split into cubic meter increments.
This is a clear reminder to report posts you think are trolling or fanboying instead of responding.
This is a clear reminder violations of the Steam Discussion forum rules, or this specific Game's forums rules will not be tolerated.
Thank you.
To those who do the right thing reporting such posts instead of interacting or providing vigilante justice commentary I would like to offer my thanks.
