Hello,
I got big problem with tree shadowing. Ive got billboard start parameter at 350 units, billboard fade 200 units.
Tree them self works great - they fade from billboard to normal mesh very good. But when my tree goes out of camera - but shadow is still viewable - i got this effect that tree going into billboard when i moving camera view target out of it.

Only solution I found is to turn up billboard start parameters to very high (but my fps drops very much) or set billboard fade to 0 units - and this way my trees pops without any fading into scene - its not nice.
I found out too - that this only happening on four cascades shadow - on 2 cascades all works great. But quality is not good for me so I must stick to 4-cascades shadows.
Any ideas? I try everything - i search forum for answers but nothing I found.
p.s I got this effect in editor too - not only player
