CameraFacingUpAxisOption Source code

The axis of the mesh to point up when camera facing the X-axis. CameraFacing_NoneUP No attempt to face an axis up or down. CameraFacing_ZUp Z-axis of the mesh should attempt to point up. CameraFacing_NegativeZUp Z-axis of the mesh should attempt to point down. CameraFacing_YUp Y-axis of the mesh should attempt to point up. CameraFacing_NegativeYUp Y-axis of the mesh should attempt to point down.

CastShadows Source code

If TRUE, has the meshes cast shadows

DoCollisions Source code

UNUSED (the collision module dictates doing collisions)

CameraFacing

bApplyParticleRotationAsSpin Source code

If TRUE, apply 'sprite' particle rotation about the orientation axis (direction mesh is pointing). If FALSE, apply 'sprite' particle rotation about the camera facing axis.

bCameraFacing Source code

If TRUE, then point the X-axis of the mesh towards the camera. When set, AxisLockOption as well as all other locked axis/screen alignment settings are ignored.

CameraFacingOption Source code

The camera facing option to use: All camera facing options without locked axis assume X-axis will be facing the camera. XAxisFacing_NoUp - X-axis camera facing, no attempt to face an axis up or down. XAxisFacing_ZUp - X-axis camera facing, Z-axis of the mesh should attempt to point up. XAxisFacing_NegativeZUp - X-axis camera facing, Z-axis of the mesh should attempt to point down. XAxisFacing_YUp - X-axis camera facing, Y-axis of the mesh should attempt to point up. XAxisFacing_NegativeYUp - X-axis camera facing, Y-axis of the mesh should attempt to point down. All axis-locked camera facing options assume the AxisLockOption is set. EPAL_NONE will be treated as EPAL_X. LockedAxis_ZAxisFacing - X-axis locked on AxisLockOption axis, rotate Z-axis of the mesh to face towards camera. LockedAxis_NegativeZAxisFacing - X-axis locked on AxisLockOption axis, rotate Z-axis of the mesh to face away from camera. LockedAxis_YAxisFacing - X-axis locked on AxisLockOption axis, rotate Y-axis of the mesh to face towards camera. LockedAxis_NegativeYAxisFacing - X-axis locked on AxisLockOption axis, rotate Y-axis of the mesh to face away from camera. All velocity-aligned options do NOT require the ScreenAlignment be set to PSA_Velocity. Doing so will result in additional work being performed... (it will orient the mesh twice). VelocityAligned_ZAxisFacing - X-axis aligned to the velocity, rotate the Z-axis of the mesh to face towards camera. VelocityAligned_NegativeZAxisFacing - X-axis aligned to the velocity, rotate the Z-axis of the mesh to face away from camera. VelocityAligned_YAxisFacing - X-axis aligned to the velocity, rotate the Y-axis of the mesh to face towards camera. VelocityAligned_NegativeYAxisFacing - X-axis aligned to the velocity, rotate the Y-axis of the mesh to face away from camera.

Mesh

bAllowMotionBlur Source code

Allow this mesh emitter to render using motion blur. This adds a velocity rendering pass

bOverrideMaterial Source code

If TRUE, use the emitter material when rendering rather than the one applied to the static mesh model.

Mesh Source code

The static mesh to render at the particle positions

MeshAlignment Source code

The alignment to use on the meshes emitted. The RequiredModule->ScreenAlignment MUST be set to PSA_TypeSpecific to use. One of the following: PSMA_MeshFaceCameraWithRoll Face the camera allowing for rotation around the mesh-to-camera vector (amount provided by the standard particle sprite rotation). PSMA_MeshFaceCameraWithSpin Face the camera allowing for the mesh to rotate about the tangential axis. PSMA_MeshFaceCameraWithLockedAxis Face the camera while maintaining the up vector as the locked direction.

Orientation

AxisLockOption Source code

The axis to lock the mesh on. This overrides TypeSpecific mesh alignment as well as the LockAxis module. EPAL_NONE - No locking to an axis. EPAL_X - Lock the mesh X-axis facing towards +X. EPAL_Y - Lock the mesh X-axis facing towards +Y. EPAL_Z - Lock the mesh X-axis facing towards +Z. EPAL_NEGATIVE_X - Lock the mesh X-axis facing towards -X. EPAL_NEGATIVE_Y - Lock the mesh X-axis facing towards -Y. EPAL_NEGATIVE_Z - Lock the mesh X-axis facing towards -Z. EPAL_ROTATE_X - Ignored for mesh emitters. Treated as EPAL_NONE. EPAL_ROTATE_Y - Ignored for mesh emitters. Treated as EPAL_NONE. EPAL_ROTATE_Z - Ignored for mesh emitters. Treated as EPAL_NONE.

Pitch Source code

The 'pre' rotation pitch (in degrees) to apply to the static mesh used.

Roll Source code

The 'pre' rotation roll (in degrees) to apply to the static mesh used.

Yaw Source code

The 'pre' rotation yaw (in degrees) to apply to the static mesh used.
