tearing in scenes

so we did another test and re-processed the same scene again using the same images and you can see the tearing now in the textures as well. the first image is the original scene from +/- 4 months ago and the second image is the same scene re-processed just now. The only difference is the reduction to 20 mil polys… 

you can see very clearly the tearing in the textures here although the geometry is slightly better it also has many defects
