Actor Merge combine poly bug


we use UE 4.17.2

when we use Actor Merge tool.

static meshes are same material.

look fine. but wire frame view

1. inside polygon does not remove in mesh.


2. Use Landscape Culling flag not work too.

i try all actor merge option. it doesn’t work. :frowning:


The Merge Actor tool doesn’t remove polygons that overlap other static meshes. To do this you would need to use our HLOD tool to merge actors and reduce the poly count.

However, Landscape Culling does work correctly in 4.17.2. Make sure you select the Landscape in the level and enable the “Use Landscape for Culling Invisible HLODVertices”.
