It is suitable for simulating vegetation a lot while keeping performance high. Mesh Clutter is an object used to scatter a large number of identical meshes across the world. UNIGINE provides additional objects to take full advantage of mesh batching: This is why sometimes it is reasonable to create Texture Atlases, so even objects using different textures could share the same material in order to be subject to batching.
UNIGINE performs DIP batching: all opaque surfaces are automatically grouped and rendered in batches according to materials assigned, thus decreasing the number of DIP calls and, therefore, increasing the performance.
You are rather accustomed to Merge Actor and use the Proxy Geometry tool as a way to reduce the number of draw calls by combining static meshes and materials they use. There is no Draw call batching in Unreal Engine as is. To learn more about configuring different types of shadows, follow the dedicated links: The shadow settings are available per each light source. World light source uses an advanced shadow mapping technique called Parallel-Split Shadow Mapping to handle shadows at large distances, it is pretty close to the Cascaded Shadow Maps technique the Directional light source uses in Unreal Engine. This is controlled by the Penumbra Mode and Filtering Mode parameters per each light source. You don't have to bake shadows to achieve the soft shadows effect. Use the Shadow Mode to decide whether the surface is static or dynamic. By using the Mixed mode you can combine baked shadows from static geometry and realtime shadows cast by certain dynamic meshes. The Mixed or Static Shadow Casting Mode of a light source filters the surfaces that cast shadows from it. Apparently, moving lights should be Dynamic, we can't precompute shadows cast from a moving light source.
All light sources can be either in Dynamic or Static mode according to which it is decided if shadow maps are computed in real time or saved in an asset, thus significantly reducing the number of polygons rendered each frame. Shadows are cast using a commonly used technique called Shadow Mapping. When it comes to light baking (including shadows), UE4 workflow implies using Lightmaps.Ĭonsidering the concept of realtime and precomputed shadows, UNIGINE provides both types of shadows from light sources. In UE4, light sources can be Static, Stationary, actors have the same modes. Show older versions >|Hide older versions << UNIGINE 2.16.1 (Latest) (Unsupported SDK).
