Product: iClone 8 (RTX Render Open Beta)
Beta Build: iClone8_RTX_Beta1_0725
Feature Area: Look At Camera / Look At Target (Animation constraint)
Category: Viewport refresh / RTX render engine

Summary
Look At Camera / Look At Target pose does not visually update in the RTX viewport when the constraint is set or changed. The correct pose only appears after manually scrubbing the timeline, it does not resolve on its own during playback or immediately after applying the setting.
Steps to Reproduce
Open a scene in RTX Render mode (iClone8_RTX_Beta1_0725).
Select a character and enable Look At Camera (or Look At Target) in the Animation panel.
Observe the viewport, the character's eyes/head do not update to the new Look At pose.
Scrub the timeline (drag the playhead back and forth).
The Look At pose now appears correctly.
Expected Behavior
The RTX viewport should reflect the Look At Camera/Target pose immediately once the constraint is applied or its target changes, without requiring a manual timeline scrub.
Actual Behavior
The pose change appears to compute correctly (it resolves once the timeline is scrubbed), but the RTX viewport does not redraw to reflect it until that manual scrub forces a frame re-evaluation.
Additional Notes
Not yet tested in DX11 mode on this scene to confirm whether the issue is RTX-specific or present in both render engines, happy to test and follow up if useful for triage.
This may be related to how the RTX viewport handles live constraint updates versus baked keyframe data, since RTX Render runs as a separate rendering/viewport path alongside DX11.
