HISM go to DrawDynamicPrimitives in profiler

Hello everyone! :slight_smile:
in my project i have a 150 BPs with HISM components (5-10 instaces in each BP) cause of occlusion reasons.
and then i rum profileGPU/statGPU or profile my project with intel GPA. I see in Base Pass - Dynamic drawing and it`s take at least - 70% of basepass time (even it less then 30% of drawcalls)
when i select dynamic in intelGPA for highlight object - it goes to foliage (material without moving) and my BPs, even all in blueprints is static :frowning: Why?
