I tried to track when this crash started to occur for me and then I
found out the crash started to occur at commit r44375, which added the
following:
--- a/blender/source/gameengine/Converter/BL_BlenderDataConversion.cpp
+++ b/blender/source/gameengine/Converter/BL_BlenderDataConversion.cpp
@@ -907,6 +907,7 @@ RAS_MeshObject* BL_ConvertMesh(Mesh* mesh, Object*
blenderobj, KX_Scene* scene,
return meshobj;
// Get DerivedMesh data
DerivedMesh *dm = CDDM_from_mesh(mesh, blenderobj);
+ DM_ensure_tessface(dm);
MVert *mvert = dm->getVertArray(dm);
int totvert = dm->getNumVerts(dm);
Does anyone know what's the role of the function DM_ensure_tessface?
Thanks,
Wander
