GPUParticlesCollisionHeightField3D
A real-time heightmap-shaped 3D particle collision shape affecting GPUParticles3D nodes.
class GPUParticlesCollisionHeightField3DA real-time heightmap-shaped 3D particle collision shape affecting GPUParticles3D nodes.
Heightmap shapes allow for efficiently representing collisions for convex and concave objects with a single “floor” (such as terrain). This is less flexible than GPUParticlesCollisionSDF3D, but it doesn’t require a baking step.
GPUParticlesCollisionHeightField3D can also be regenerated in real-time when it is moved, when the camera moves, or even continuously. This makes GPUParticlesCollisionHeightField3D a good choice for weather effects such as rain and snow and games with highly dynamic geometry. However, this class is limited since heightmaps cannot represent overhangs (e.g. indoors or caves).

var followCameraEnabled: BoolIf
true, theGPUParticlesCollisionHeightField3Dwill follow the current camera in global space. TheGPUParticlesCollisionHeightField3Ddoes not need to be a child of theCamera3Dnode for this to work.var resolution: GPUParticlesCollisionHeightField3D.ResolutionHigher resolutions can represent small details more accurately in large scenes, at the cost of lower performance. If
updateModeis .always, consider using the lowest resolution possible.var size: Vector3The collision heightmap’s size in 3D units. To improve heightmap quality,
sizeshould be set as small as possible while covering the parts of the scene you need.var updateMode: GPUParticlesCollisionHeightField3D.UpdateModeThe update policy to use for the generated heightmap.
