Unity crashes when enabling Mesh Renderer Lightmap Static
How to reproduce:
1. Open attached project "map"
2. In Hierarchy select TerrainBag/Default Terrain0/LowPolyTerrain
3. In Inspector tick Mesh Renderer/Lightmap Static checkbox
--------------------------------------
Observe crashing
Reproduced with: 2018.3.11f1
Could not reproduce with 2019.2 as the checkbox has been removed.
Does not reproduce with 2019.1, but ticking checkbox constantly produces these errors:
[PathTracer] Failed to add geometry; mesh is missing required attribute. Please make sure mesh contains positions, normals and texcoord0.
[PathTracer] AddGeometry job with hash: 66b0b10e164295898602f480784ec297 failed with exit code 1.

Sorry for question, but can you explain, what do you mean on "to make sure that the meshes used for baking (lightmap static objects) have positions, normals and texture coordinates"?
All objects have positions and texture coordinates (if they have UV map).
So I don't understand what i have to change to avoid PathTracer error? -

This has been fixed in 2019.1.
The workaround for earlier versions is to make sure that the meshes used for baking (lightmap static objects) have positions, normals and texture coordinates.

Resolution Note:
This has been fixed in 2019.1. The fix is not easily backportable. The workaround is to ensure that positions, normals and texcoords are available on meshes used for baking.
