build: Failed getting triangles. Submesh topology is lines or points.

[unitycoder]

meshconverter, 2020.2.7f1

errors in build:

Assertion failed on expression: 'subMesh.topology == kPrimitiveTriangleStrip || subMesh.topology == kPrimitiveQuads'
UnityEngine.GUIUtility:ProcessEvent (int,intptr,bool&)

Failed getting triangles. Submesh topology is lines or points.
UnityEngine.GUIUtility:ProcessEvent (int,intptr,bool&)

cause:
if you convert ply with Normals, those gameobjects have Batching static flag set. (which causes those errors in build)

solution:
after conversion, select meshes, disable static batching from the dropdown (for all meshes)
