see attached image.. this is with the default texture. the same happens on the rolled tarp. also happens with no texture at all. if rendered with poser 5 engine, the pictured occurs. poser 4 engine has much smaller black artifacts, but they are still there. happens even when I change material completely (i.e. to gold). tried reinstalling the chuckwagon, no change. odd fact: if I load the .obj of the tarp in bryce, I can see random triangles in the wireframe preview which seem to match up with the ones pictured.. however if the object is rendered in bryce, no visible artifacts. tried messing with the texture mapping settings, no change. without wagon, the artifacts appear brown instead of black. any ideas? no issues with any other probs, the wagon itself, or any other item, only the tarp.
