So I am in the process of biting off more than I can chew and hope I might be able to get a little advise on more affective mastication.
I am looking at creating a landscape based on a real world location at 40km2. Only about a 20km x 4km strip will be playable. The reason I am importing a terrain so much larger than the playable area is so I have a reference for how the landscape will look in the distance. Once I have figured that out I will replace the distance landscape with much simpler terrain, art, possibly obscure it with fog, see which bits would never be visible to the play anyway etc.
At my disposal I have UE4, Houdini Indie and World Creator 2. I am able to get data on the area from terrain.party however the terrain data is not great.
Here is the process as I currently see it, though there might be much better options.
- Get the data from terrain party.
- Import it into wold creator at a 1 to 1 scale of 40km x 40km.
- Work into it in depth in world creator using the import as a guide for where there are rivers etc. This will be a fair bit of work but means I will get the geography correct.
- Export from World Creator 2 as tiles
- Import the tiles into UE4 using world composition.
What I am trying to confirm is if there are better options keeping in mind my intended goals, which are as follows.
1 . would like the distance between locations, river locations etc to all be correct, so I need to be working from an accurate map or imported data etc.
2. As Houdini and World Creator 2 have more sophisticated tools for making great looking landscape I would like to do all of base terrain world outside of UE4.
3. I would like to create some base masks for landspape textures layers so that my landscape starts with some good defaults. For examples cliff sides / banks etc already have a different texture to flat areas, areas with certain elevations have a different texture to areas of lower elevation etc.
4. Once in UE4 I can then make alterations to terrain as I add building, tweaks for performance, to hide certain areas, tweaks for gameplay etc.
This is obviously a pretty broad topic. Does the approach above seem realistic, reasonable, wise? Are there other better options? Any advise from those who have done this, or tried and failed?
