From my tests so far, I've noticed that the 3d models from aerial imagery tend to be worst (much more triangulated), in version 091 than in version 090 (images attached), using the same parameters. The calculation must be different because the final number of polygons is very low for the same "0" value in the number of desired polygons. It seems that, by default, Photoscan optimizes or decimates the model instead of produce the maximum possible number of polygons. How do we use the same functionality of the last version to produce the biggest amount of polygons?
By the contrary, orthophotos are a lot lot better in 091 that in 090. Sometimes this difference is impressive!!
Considering the "Can't build model error", these are the Graphical Card specifications:

OpenGL Renderer: NVIDIA GeForce 9600M GT OpenGL Engine
OpenGL Version: 2.1 NVIDIA-8.0.61

And this is the error:

PS: I've just tested a new run and, if I put 10 000 000 faces in the "Face count" option the same 9 plus million faces, as in the previous version, are generated. It would be great to get these biggest possible amount using "0" in this option, as in the previous version or something a little more intuitive. In the case of this model I knew the maximum amount of faces in advance but, in a new project, the only option will be using a very big number to avoid guessing....
