Hello,
I rendered 3 different images to visualize the problem: The first one is frame 01 projected on the geo with occlusion on. The second is frame 150 (test) which I like to fill the the occlusion with. The third are the two blended together.
But you can already see in image one that outline from frame 1 around the occlusion. The same problem in the other example. The black lines in that example are also the outline from the buildings. The occlusion is somehow 1 pixel short...
Hope that helps
Best,
