terrain method for UE4

ArcaneLeo

hi, im creating a project, the world are not too big and not too small too,
and it have multiple island , and some area like forest are restrict for explore, so people focused exploring on main area that created for exploration
its semi open world but i should restrict some unnecesary area so player can focus on playing, and i can focus only
modelling and create a silhouette of specific area
i want to ask for opinion
should i use terrain or basic modeling for the terrain?

as i know, using terrain can produce so much of bug, the slope texture are look not good
take too much polygon

if use basic modelling, it took not too much polygon, it has more of creative freedom
it more controlable, but it hard to make a good natural organic shape

the wicher use terrain, and uncharted use basic modelling
and there should be a good reason why they choose what they choose

and i really confuse with methods i should adobt,

You can set landscape in unreal to stream in and out in chunks. If you use displacement you can also set it to tesselate based on distance. This will stop it from using up your polygon count. If you're concerned about polygon count using static meshes would be more difficult. https://docs.unrealengine.com/latest/INT/Engine/Landscape/TechnicalGuide/index.html#performanceconsiderations You might also want to look into world composition: https://docs.unrealengine.com/latest/INT/Engine/LevelStreaming/WorldBrowser/index.html

yeah im concerned a bit about the polycount
and whenever i use terrain, i confuse where to start, it so huge
and there a bit confuse about proportion
and sometime there uneccesary polygon all arount the place

thanks for the info sprunghunt, maybe i stick with the terrain method
