Engine v4.5.1
May 23, 2026
A patch in the Surface Tension line.
what's new
- Ponds run much smoother without changing how they look.
- Plants and ground decorations now stay on the ground when you reshape terrain.
›technical notes
- Improved water rendering performance by rendering transparent double-sided water in a single pass and omitting inactive TSL viewport color/depth copy nodes from lightweight water material variants.
- Shares one viewport depth capture across rich-water depth samples, reducing duplicated full-screen depth resources during rendering and resize.
- Rebuilds water material viewport topology when depth, shoreline foam, or refraction features change so live edits retain the intended appearance.
- Keeps renderer resize at the same capped pixel ratio used during startup, preventing high-DPR screens from unexpectedly quadrupling full-screen water and post-processing work after resize.
- Fixed terrain decorations using stale height data after live terrain reshaping.
