LA4-7263: Crash On Reopen Project (asset Versioning)

Fixed a crash when a corrupted project file containing invalid asset version information.

Status: Done | Requesters: MPR

LA4-7247: Trigger Volume Node

Introduced a Trigger Volume node for spatial queries.- Inputs: Positions (vec3 array) and a Primitive (Box or Sphere). Selecting an incompatible object shows a warning.- Outputs: On Inside (fires continuously when at least one point is inside), On Enter (fires once when a new point enters), On Exit (fires once when the point count decreases), and Objects Inside (int count).- Behavior: Evaluates whether any provided positions are within the selected primitive, fully respecting the primitive’s position, rotation, and scale.

Status: Done

LA4-7229: Jumping To Previous Landmark/cues If Playmode == Playing

Fixed an issue where in Play mode, the previous-cue buttons only returned to the start of the current section and never to the actual previous cue, even with rapid presses. Restored the intended logic: if playback is within n seconds after a cue, jump two cues back; otherwise, jump to the nearest cue before the current time.

Status: Done

LA4-7228: Crossfade If One Of The Layers Exists Across Both Sections

Fixed an issue where, during crossfades (Dip/Hold) between sections, the exception layer rendered on top, leaving Color Grid above until Gradient/Checkerboard appeared abruptly. Crossfades now preserve background continuity: non-exception layers transition normally, while the exception layer is rendered to a texture on the source side and reused at the correct moment on the destination. Included in 4.16.1.
