I've noticed that in the current version of PhotoScan that I can get a bit more detail in my textures if I lower the texture size and increase the count (38,000 x 1 or more than c.30,000 x 2 seems to be the limits on my kit).
How can I use the texture UV maps in Blender? i.e.: how can more than one be mapped to the model and how does one go about it? I know how to map one image when I've imported the model into Blender, but two has me stumped...
