All nodes have Tiling Mode set to "H and V Tiling" So essentially, we have 4 tiles exported from world machine, and I'm trying to make AO's and Normals based on the exported height maps. But we get these black seams inbetween each height map. The height maps themselves do not tile, but they certainly don't have these giant…
Thank you for the input! Made a similar discovery. I was able to get around it by forcing No Tiling on the AO node itself, and turning GPU optimization off, that got me a comparable AO that connects to the other tiles rather seamlessly.
