Hi, in the old FPP times, there was the ability of applying tint over the images, this was partucullary very practical when you wanted to template and schema, so with the same graphics you could change the color of the template...
I think this must be not very difficult and very effective at the same time...
I think that you could only tint them once they had a white color...
Hope we can see that soon, between those great features that comes with the best pano tour software ever !!
