Mixing Scenery

Postby NormanLGibson » Sat Feb 17, 2018 11:14 pm

Following a suggestion by a forum member here https://www.prepar3d.com/forum/viewtopi ... 6&t=127412 I have resampled my Northern Territory Imagery files.

Following is a test video made using a lower LOD for 15m imagery scenery so that the higher resolution default or generic land class scenery would show at lower altitudes and the "real" imagery comes into view as you climb. A good color matching generic scenery would be best to minimise visual differences as you climbor descend where you can see both sceneries together. Perfect for airline flights.

The video is The Northern Territory of Australia. This scenery only uses 3GB of HD space as against I estimate around 300GB would be required for a high resolution imagery scenery for the whole state.

Here is another test video that I have made. With ORBX permission to make public comparisons, I have ORBX AU enabled in Prepar3d v4.2 and my 15m Imagery based scenery with an LOD such that you will see ORBX AU at lower levels and my 15m imagery show more as you climb and the reverse when descending. At the lower altitude at the beginning of the video ORBX is obvious with the autogen and high resolution textures showing. In the distance you will notice the 15m imagery mountains. There are times when you cannot differentiate between the two.

The benefits of this method of "dual scenery" are that you can have higher resolution landclass type scenery for lower flights and real scenery at higher cruise altitudes. Both these sceneries take up much less HD space than a single high resolution imagery based scenery and at a much reduced cost, especially in countries that have not any low cost high resolution imagery.

The video is in northern NSW in Australia.

It would be a good feature in any future Prepar3d release to have a blend at a certain altitude where the two sceneries can be seen together. At the moment the change is seen as blocky textures appearing and dissapearing in the distance.
