LogInLet's have a look at the latest version of UNIGINE.
The biggest thing is the new terrain system which has been in development for 2 years. It is based on the Sparse Virtual Texture (MegaTexture) approach with improvements and engine-specific tweaks (smart details caching, optimized culling techniques, and more).
"The terrain system is tightly integrated with Engine's advanced streaming subsystem, making it VRAM-efficient, and is designed from the ground up with multithreading approach in mind enabling it to utilize the advantages of multi-core systems and handle up to petabytes of data efficiently," noted the team.
Please note that it is available for both DirectX and OpenGL API. The team strongly recommends using a GPU with at least 4 GB of memory for optimum performance. It is worth noting that the practical limit for the new terrain up to 10000 x 10000 km.
Other updates:
- Improved C++ and C# API: simplified object management, improved thread safety, and stability, better code readability.
- UnigineEditor extensions: public API, plugin system.
- High-Level Car Physics System: wheeled vehicle simulation.
- Improved clouds: more types, better visuals.
- IG updates: adaptive quality management, better synchronization, easier configuration, API improvements.
- New Build tool for assembling standalone project builds.
- Texture Profiler tool for assets optimization.
