Aevyrie 8130b229be Transform Propagation Optimization: Static Subtree Marking (#18589) ... # Objective - Optimize static scene performance by marking unchanged subtrees. - [bef0209](bef0209de1) fixes #18255 and #18363. - Closes #18365 - Includes change from #18321 ## Solution - Mark hierarchy subtrees with dirty bits to avoid transform propagation where not needed - This causes a performance regression when spawning many entities, or when the scene is entirely dynamic. - This results in massive speedups for largely static scenes. - In the future we could allow the user to change this behavior, or add some threshold based on how dynamic the scene is? ## Testing - Caldera Hotel scene		2025-03-30 02:43:39 +00:00
