I have a scene that keeps getting stuck in the same spot with this in the log: 

[2012-08-14 16:34:34 Info: 0] Shape #85 (plymesh): Applying 1 levels of loop subdivision to 14960 triangles

[2012-08-14 16:34:34 Info: 0] Shape #85 (plymesh): Subdivision complete, got 59840 triangles

[2012-08-14 16:34:34 Info: 0] Shape #85 (plymesh): Applying displacement map to 31479 vertices

[2012-08-14 16:34:34 Warning: 43] Shape #85 (plymesh): Inconsistent shading normals in 175 triangles

Any idea what this is?  I narrowed down the object from this line "Shape #85 (plymesh): Loading PLY mesh file: 'reality_scene-Resources/objects/001-Harness_001-Harness_HChestStrap_130.ply'..." so I assume it's the chest haress causing problems but I don't know what.  I thought it was smoothing so I turned that off, and there's no subdivision.  Any ideas on how to trouble shoot this further?
