All flora elements have spring, summer, autumn and winter versions. Also there are two versions of medium and big size trees (urban and forest). Urban versions are healthy trees that suitable for landscape gardening in urban areas or forest areas that are not dense. Forest versions are suitable for dense forest environments.
All branches and foliages have wind animation and also color variation depending on their position on the map. These can be adjust via material parameters.
For UE 5.1, all models support Nanite (except landscape grass). Trees, rocks, stones and outer meshes have high poly meshes.
For UE4.x and UE 5.0, all models have LODs. All big flora objects have four LODs (100%, ~40%, ~5%, billboard)
All models have collisions (trees have capsule, others have auto generated).
All winter rocks have dynamic snow layer.
All textures are set for PBR.
All terrain textures are photoscanned from same area and they have same texel density.
Also there is a road mesh with photoscanned footprint POM material for creating snowy road with footprints.
There are 7 example levels for 4 seasons and a showcase level for models.
Technical Details
Trees use 4 different photoscanned barks in two textures (2048×4096, 4096×4096), 1 tilable (1024×2048) and 1 branch texture (4096×2048) for each season.
For UE4.x and UE 5.0, trees have 4 LODs. For UE4.x, base LODs’ barks have tessellation. Last LODs are billboards. For UE 5.1 and above they use Nanite high poly meshes.
Example:”poplar_a_medium_c_forest” model’s LODs have 12694, 5153, 592, 6 triangles.
