I have a scene with some custom flower models (5, with different materials) scattered over a huge rock formation. I am using UV mode as the rock has a few overhangs, so XY mode wont put flowers under the overhang.
I have some slope restriction to make the flowers appear more in the flatter areas.
I have no camera clipping restrictions.
My problem is that when i render the sequence i see some flowers disappear\move slightly\change colour for a frame before returning to normal..
I see it exhibit a similar jittering in the viewport, but i am unsure if the same "problem" flowers are in the render or if its different ones.
The render is stable when XY mode is used.
My work around for now, is to break the geometry down so the overhangs are seperate, then have multiple forests on XY mode.. obviously this is not ideal.
