on regular zoom on 2D map the arrow shows fine but from 1500m the arrow starts to crumble.
till its destroyed completely and there is only a line with side effect, I would upload an example but it doesn’t allow me to upload the pictures.
Would you be able to share a Sandcastle that replicates this issue?
this is 13meters above ground
and this is 2151m above ground
@nikitakogan I believe this may be another instance of this existing issue: Polyline with Arrow Material clamped to ground, the arrow head is choppy/glitchy. · Issue #7645 · CesiumGS/cesium · GitHub. Unfortunately, I don’t think we have any easy workarounds for this at the moment.
