Objects placed on the opposite side of the globe and configured to obey Unreal Engine gravity will “fall” into space! That’s probably not so bad for most applications, but by the time we get to the opposite side of the globe, the gravity direction is 180 degrees from what we expect it to be. A hundred kilometers away from the origin, the gravity direction will be “wrong” by about 1 degree. To be precise, the down direction changes by roughly 0.01 degrees for every kilometer we move from the origin. Click the Cesium3DTileset in the World Outliner, find the Cesium -> Tile Culling section in the Details panel, and uncheck Enable Frustum Culling.ĭue to Earth curvature, the farther we move away from the CesiumGeoreference origin location, the less the Unreal Engine minus Z direction is an accurate representation of the local “down” direction. To avoid these problems, we can disable view-frustum culling for tilesets that are important for physics, shadows, and other purposes. Similarly, a tall building will stop casting a shadow when you turn our back on it, because it truly ceases to exist in the Unreal Engine world. Suddenly the character is hovering over a void, and they start falling to their doom! The tile the character was standing on is no longer visible, and so it will be culled. Now you turn around so your back is to the character. Unreal Engine’s gravity simulation holds the character to the surface. Imagine a character in front of you, standing on the Cesium World Terrain surface.
They can’t cause any physics interactions. Culled tiles are not sent to Unreal Engine at all, which means: However, culling comes with an important caveat: if you don’t see it, it doesn’t exist. Culling these tiles means less data downloaded and less load on Unreal Engine to render the tileset, improving runtime performance and efficiency. A key form of culling is view-frustum culling, which excludes tiles that are behind the viewer or otherwise outside of its field-of-view. In broad terms, Cesium for Unreal selects high-resolution tiles for parts of the model that are close to the viewer, and lower-resolution tiles for parts that are farther away.Ĭulling means that we don’t load or render parts of the model that aren’t visible. Level-of-detail means that the complete tileset is broken into a multi-resolution pyramid of individual pieces, called tiles. They perform two functions that are essential for rendering datasets that can easily measure in the terabytes or larger: level-of-detail and culling. This, in turn, avoids a rendering artifact called “jitter”, where rounding errors in large coordinate values of a camera and another object near the camera cause the object to appear to “jump around” as either the camera or the object moves.Ĭesium for Unreal’s Cesium3DTileset actors stream massive datasets into your application in a view-dependent manner. This ensures that objects near the viewer have small coordinate values, and thus can be represented very precisely. When the OriginLocation is changed, the floating-point coordinate values of every object in the level are updated such that all objects are in the same position as they were before relative to each other, but now the newly-specified OriginLocation is the center (0, 0, 0) point of the game world.īy default, the CesiumGeoreference automatically rebases the world origin to be near the viewer as the viewer moves around the world. It works by keeping a separate OriginLocation as a set of integer (rather than floating-point) coordinate values. Origin rebasing is an Unreal Engine feature that helps preserve vertex precision in very large worlds. Player Info (Modify health, modify ammo, change outfit, teleport.
