I have not much experience with the Unreal Engine and I didn’t understand the tutorial, so this is my question.
How and where do you create a vehicle, I would like the make a pirateship, or is there a place with free vehicle models?
You can download a model (give credits, or look what is need in the licence, to be a “good one”, if you are using the blendswapstuff), and modify it on your own. Blend Swap | All Blends
I would suggest you blender, because the community is great, a bit like in the UE forums. ^^ slimeattack ahead
Stay focused and decide, what to learn, depending on how much time you have to invest.
Start easy, if you want to understand the full potential of blender (export to UE working well).
