Texture Quality Amazing for Small Area, Awful for Larger Area in the Same Dataset?

Thanks for your fast replies Steven and Götz, I’ll try today with the measured control points and see how that goes. Here’s some more details and screenshots of the scene. Same data set with two reconstruction areas; the small section, and the a larger defined reconstruction area. 

Large Area - Low Texture Quality

Small Area - Good Texture Quality 

Large Area - Mesh Quality 

Small Area - Mesh Quality

Large Area - Mesh Close Up

Small Area - Mesh Close Up

Maybe these screen shots will shed some more light on the issue. I will update soon with results from adding measured control points. 

Thanks again!
