Vehicle on a track simulator

I’m wanting to make a train simulator. I know how to model objects, but when it comes to actually creating a game I need to find some more specific tutorials.

For one, I’m not sure if I should even be doing this part in blender and should use blender for modeling then something like Unity3d or C4 for the engine portion.

The next part is creating huge above and underground worlds and the performance issues that come with that without dealing with loading screens or performance hits. Basically need something that will manage a view distance and load on the fly. But then unsure how I should store my “levels” or maps.

The final part would be an actual good vehicle tutorial on a train (or anything I could adapt) to follow a track.

I’m not looking for any hand outs, just to be pointed in the right direction.

I appreciate any help. Thanks!

If you want to make large worlds with a moderate to high amount of detail, you’ll probably need to implement dynamic loading, LoD system, or both. Blender can handle large worlds fine as long as you take the necessary steps to keep rendering and physics calculation times down.

As for the train physics, I’m not sure how well the Bullet engine will handle that since I’ve never tried. It really depends how you decide to design it and how complex you want it to be. If it doesn’t give you good results, it may be better to program the physics yourself in Python.
