I downloaded ViaducBusseau1,<kuid2:119452:136:4> and tried it in both TS2009 and TRS2004 and it won't show. There are no errors or missing dependencies. In CM2, I tried to edit in CCP and the mess doesn't show up there either. Something must be wrong with the mesh. The puzzling thing about this asset is the config.txt file says it's kind mospeedboard but the mesh looks like a very long pair of bridge guard rails.
