I am using speedtree (8.3.0) for my foliage. (UE 4.22)
The wind animation for the trees is done via World Position Offset.
Unfortunately, the raytraced shadow is being rendered beforehand and doesn’t take the World Position Offset into account.
That leads to two problems:
- the shadow is not animated.
- the self shadowing is showing really ugly artifacts (see thumbs), when animated.
I understand, where the errors are coming from and I wonder, if there is a way to render the shadows with Word Position Offset. May be by changing the order of tasks?
