I don't disagree with the fact that World Machine can help make awesome terrains(and quickly).  My point is more about the fact that the OP(going by the questions asked) is nowhere near needing that kind of quality yet.  The poster is asking about modelling software but then goes on to say that the models and textures(and music/sounds) are already covered, leading me to believe that this person is at the beginning of the journey and needs to learn the basics first.

I think I said most of them are covered, some have to be heavily modified and the main ones need to be made for scratch. So, World Machine would be great to focus on other things.

Oh, that is already covered, including the various model/texture assets.

That is the quote...doesn't say most anywhere.  Regardless...even if it is just some of the stuff that is covered, I still think you should worry about the basics first, before investing any money into anything.  Once you have worked the basics and done a few smaller projects, you then have a better idea what you actually need, and what you really have covered by your help(or wherever you have the assets "covered").

Yes, that's exactly right.

I'm currently into the nitty-gritty of UE4 and Maya 2018, and can already tell that Houdini would be a nice fit down the line. It even has a Maya and UE4 plugin!

And I'm very pleased with Maya; I already made a pretty great dynamic tank treads. Maya 2018 especially has a lot of potential for simulated and dynamic content.

That's good news, and basically the biggest recommendation you get when starting out......just pick something small, and do it.  You don't have to spend the money until later when you know you actually need something, and by that point you can really justify the spending.
