Modify Foliage transform failed in UE4.20 for shiping client

Dear friends:
In shipping package I call updateinstancetransform function to change foliage’s rotator,but It’s failed in rendering to update foliage’s rotator.
I have to call initperinstancerenderdata function after updateinstancetransform function to make it works in rendering.
But It may be not a good idea.
Is there any things I miss?

Hi Guys,I call HISM::updateinstancetransform . Please help me…
