-Disable temporal effects: FSR, TAA, and motion blur. The Terrain3D mesh is constantly moving which causes Godot to unnecessarily generate motion vectors for the terrain. A way to fix this is making it's way through Godot and will be included in a later version. Until then, temporal effects are unreliable.
+Disable temporal effects: FSR, TAA, and motion blur. The Terrain3D mesh is constantly moving which causes Godot to unnecessarily generate motion vectors for the terrain. This has been fixed in the Godot 4.5 API, but Terrain3D is built against the 4.4 API. We're not ready to abandon 4.4 yet, so to use Terrain3D with TAA, FSR2, or Motion Blur you must:
+* [Build Terrain3D](building_from_source.md) from source using the godot-cpp 4.5 branch
+* Use the Godot 4.5+ engine binary
+
+Once we offer builds against the 4.5 API, building from source won't be necessary.
