Here is a copy of a bug report I just send.Maybe someone from community might have an idea.
Add foliage of a blueprint with hierarchical instanced mesh.
Some of them will disappear.
Maybe appear ? And a coffee ?
If you use the Linux editor with OpenGL, if you put a blueprint with hierarchical instanced meshes in the map, some of the instances will disappear. I will join screen shots as attachments. The weird thing is that some parts, a bit smaller and scaled just stopped disappearing, who knows why ?
The other weird thing is that if you use ES3 or Vulkan (Desktop), everything looks fine.
Additional Notes :
Too bad the editor often crashes and contextual texts are often illegible with Vulkan, because performances look great (1070gtx Nvidia-396)
The ground, here, is made of pre-fragmented “slabs”.
